Understanding Physics Motion in a Straight Line

Understanding Physics Motion in a Straight LineFor students to be successful in their studies, they have to understand the physics motion in a straight line. The best way to get a grasp of physics is to study the subject in its elementary form - first with reference to the laws of physics and then with the help of the concepts. Now the student is required to learn this subject in a way that suits his/her interest. Here are some of the interesting ways of learning the science.There are many advantages associated with the subject and one of them is that it can be easily understood by the child. There are no harsh words that are not clear to the child. Instead, a simple explanation can make the child relate to the subject better. Now a child is learning about physical phenomena like gravity, motion, force and energy. These elements of physics help the child in their future pursuits.Students need to study in high school if they want to know the subject well. This is because science subje cts are compulsory for all schools and colleges. Though it is easy to learn in the junior classes, in the seniors' courses, students are often asked to study harder. Hence, the students have to learn the subject in a way that is suitable to their level of learning.The organic chemistry tutor can guide the students in the subject. For example, the teacher can show the students the difference between thermodynamics theory. This will make the students understand what they are studying and what they are learning. At the same time, the teacher can explain to the students why different reactions are possible. This makes the students understand the physics motion in a straight line.The organic chemistry tutor can also teach the students about the details of the reactionprocess. He/she can discuss with the students the different types of reactions and also the difference between the different reactions. The discussion helps the students to learn the subjects thoroughly. This is a great idea to help the students learn the subjects. They are normally given challenges in order to help them improve their knowledge.The organic chemistry tutor can help the students in better understanding the chemical reactions. Once the students understand the theory, they can try different things in practice. For example, they can use the chemical reagents and then try to observe the reactions on a petri dish. Sometimes, they can do experiments with the help of machines and chemicals. This will help them better understand the properties of chemical reactions.The organic chemistry tutor can help the students in the subject. He/she can show the students the value of the materials they use in the reaction. For example, if the student makes up a certain compound, he/she will have to try out various reactions to see if the compound works. The student can talk to the teacher and find out how the reaction goes. In fact, the teacher will even advise the student if the compound works.The organic c hemistry tutor can help the students in the theory. Sometimes, the teacher does the work on the students. The teacher also gives the student feedback on the reactions. This helps the student in understanding the properties of the reaction. The feedback from the teacher is also helpful in terms of motivation as the students can now learn how to produce different substances.

Understanding the Brain Chemistry of Schizophrenia

Understanding the Brain Chemistry of SchizophreniaOne of the many important and often overlooked aspects of schizophrenia is its brain chemistry. The truth is that there is no research study that has yet to demonstrate a definitive link between schizophrenia and brain chemistry. However, schizophrenia itself and the genes that increase the risk of this condition are well documented in literature and mainstream media reports.Researchers have found that schizophrenics are more likely to develop Alzheimer's disease, stroke and develop dementia than individuals without this disorder. There is also speculation that an individual with schizophrenia may have an increased incidence of heart disease, seizures and certain types of cancer. All of these conditions are associated with what is known as the dopamine system, and while researchers are not yet sure exactly how it interacts with the rest of the brain or why one person develops all of these conditions at a different rate than another pe rson, they do know that the exact biochemical makeup of this system is similar to that of a normal healthy brain.Schizophrenia itself is a serious neurological disorder. It has been shown that the symptoms of schizophrenia can actually progress and become worse if not treated properly. Therefore, although the biological and genetic factors do not yet seem to be linked with the treatment, there are a number of measures that can be taken to help to reduce the chances of developing schizophrenia.One of the most important treatments for schizophrenia is natural remedies. The most important component of natural remedies for schizophrenia is the use of garlic. Garlic has been shown to control many of the symptoms of schizophrenia, including those related to depression, anxiety and paranoia.Garlic is known to be a powerful herb that contains a compound called allicin, which is known to decrease anxiety. Moreover, it has been shown to reduce the activity of dopamine, which is known to contr ibute to negative feelings in people. As this ingredient is found in large amounts in the brain, you will find that the brain's chemical balance will actually begin to improve when you begin to use garlic regularly. Allicin has been found to promote an improvement in the integrity of neurons, which is a key part of how it improves the chemicals that enter and leave the brain.Natural remedies for schizophrenia can provide a significant advantage over medications when used in conjunction with cognitive therapy. Cognitive therapy is a form of psychological therapy that attempts to change your thought processes. It involves the assessment of both current and past beliefs, patterns of thought and behavior, which is conducted in an attempt to understand why these things happen in the first place. Cognitive therapy can provide many benefits for patients suffering from schizophrenia.It is important to recognize that while natural remedies for schizophrenia provide a number of benefits, it i s never recommended that you try to treat yourself without consulting a professional. Natural remedies for schizophrenia should only be used under the supervision of a licensed healthcare provider.

Molality

Molality Molality The concept of molality arises while studying solutions. Molality is also called as molal concentration. A solution is formed when a solute is dissolved in a solvent. Solute is a substance which is dissolved in another substance during the formation of a solution. Solute are usually in smaller quantities. The solvent is a substance which dissolves solute in itself during the formation of the solution. The solvent is usually in larger quantities when compared to the solute. For example, salt is dissolved in water here salt is the solute and water is the solvent. Sugar dissolve in juice, here sugar is the solute and juice is the solvent. Hence when a solute dissolves in a solvent a solution is formed. The solutions in which the solute is evenly distributed throughout the solvent is called as a homogeneous solution. The amount of solute dissolved in the solvents, and the solution formed can all be expressed in terms of concentrations. There are different ways in which the concentration is estimated such as molarity, molality, formality, percent composition and many more. Molality definition: The amount of solute dissolved in one kilogram of the solvent is defined as the molality of the solution. The amount of solute is expressed in moles. Therefore the molal concentration of a solution is the moles of solute in kilogram of the solvent. To find the Molality the required information is Moles of the solute used to form a solution. Amount of the solvent expressed in kilograms. Hence the formula for Molality can be expressed as follows: Units and symbol: The molality of a solution is expressed as m. The units for expressing the molality equals moles/kilograms or mol/kg. Question: Find the molality of 5 moles of Nacl mixed in 2000 grams for the solvent? Here the moles of the solute = 5 moles. The amount of the solvent = 2000 grams. Expressing the solvent in Kilograms = 2000/1000 = 2Kg. Hence using the formula for calculating Molality gives: Simplifying the calculation, Molality = 2.5 m. Question: Find the number or moles of FeO dissolved in 1.5 kg of solvent, if the molality of the solution if 0.3m. Here, the amount of the solvent = 1.5 Kg. Molality of the solvent used = 0.3 m. Hence rearranging the Molality formula for calculating the moles of the solute: This gives Moles of solute = 0.3 x 1.5 = 4.5 moles of Feo. Question: Find the amount of the solvent if 0.24 moles of the solute is dissolved to obtain a molality of 0.48m? Here, the number of moles of the solute = 0.24. The molality of the solution = 0.48 m. Hence rearranging the molality formula for calculating the mass of the solvent gives: The amount of the solvent = 1/2Kg = 0.5 Kg. Finding the moles of the solute: In a few questions the amount of the solute is given, in such cases the moles of the solute need to be calculated before using the molality formula. Here is how the moles of the solute can be calculated: Question: Calculate the molality when 20 grams of KCl is dissolved in 400 gm of the solvent? Mass of solute = 20 grams. Molar mass or molecular weight of KCl = Atomic mass unit of (K + Cl) = 39.0983 + 35.453 = 74.5513 g/mol = 74.6 g/mol (approx.) Moles of KCl = 20/74.6 = 0.27 moles. Amount of solvent in Kg = 400/1000 = 0.4 Kg. Using the molality formula: Therefore, molality of the given solution = 0.27/0.4 = 0.675 m Question: What is the molality of the solution when 15 grams of Na2CO3 is dissolved in a 0.25 kg of solvent to form a solution? Given is the mass of Sodium Carbonate = 15 grams. The number of moles of Na2CO3 is required for finding the molality of the solution. The Molar mass of Sodium Carbonate Na2CO3 = 2 (Na) + C + 3 (O). Refer the periodic table for the atomic mass unit for Na, C and O. Molar mass of Na2CO3 = 2 (22.989770) + 12.0107 + 3 (15.9994) = 105.98844 g/mol = 106 g/mol (approx.) Moles of Sodium Carbonate Na2CO3 = 15/106 = 0.14 Using the Molality formula Hence the molality = 0.14/0.25 = 0.56 m Difference between Molarity and Molality: Molarity and molality are both used to express the concentrations of a given solution. Molarity is the number of moles of solute dissolved in one liter of the solution. Molarity is also called as the molar concentration of the solution. Molarity of a substance gives the concentration with respect to the total solution whereas the molality gives the concentration with respect to the amount of solvent. The units for expressing molarity is mol/L or M. The formula used to calculate the Molarity of a solution is: Another very useful measuring unit used while solving questions related to concentrations is density. Density of a given solution is mass of the substance per unit volume. The units for expressing density are g/ml. The formula for calculating density is: Following are very unique and useful solved examples involving molality and molarity. Question: The molality of a solution formed by dissolving NaCl in a solvent is 0.56m. The density of the solution is 1.8g/ml. What is the molar concentration of the solution formed? The molality of the solution = 0.56m. This implies 0.56 moles of a solute NaCl is dissolved in 1 kg of the solvent. Moles of NaCl = 0.56; Molar mass of NaCl = Atomic weight of (Na + Cl) = (22.989770 + 34.453) = 58.44277 g/mol = 58.44g/mol (approx.) Using the moles formula, mass of NaCl dissolved = 0.56 x 58.44 = 32.73 gm (approx.) Mass of solution = Mass of Solute + Mass of Solvent = 32.73 grams + 1000 grams = 1032.73 grams Density of the solution given = 1.8g/ml. Using the density formula . Volume of the solution = 1.8 x 1032.73 = 1858.91 ml = 1.85891 L = 1.86 L (approx.). Using the molarity formula: Therefore, Molarity of the solution = 0.56/1.86 = 0.30 M Question: The molality of a solution formed by dissolving KI in a solvent is 1.2m. The density of the solution is 2.5 g/ml. What is the molar concentration of the solution formed? The molality of the solution = 1.2m. This implies 1.2 moles of a solute KI is dissolved in 1 kg of the solvent. Moles of KI = 1.2; Molar mass of KI = Atomic weight of (K + I) = (39.0983 + 126.90447) = 166.00277 g/mol = 166.00g/mol (approx.) Using the moles formula, mass of KI dissolved = 1.2 x 166.00 = 199.20 gm Mass of solution = Mass of Solute + Mass of Solvent = 199.20 grams + 1000 grams = 1199.20 grams Density of the solution given = 2.5g/ml. Using the density formula . Volume of the solution = 2.5 x 1199.20 = 2998 ml = 2.998 L. Using the molarity formula: Therefore, Molarity of the solution = 1.2/2.998 = 0.40 M
