There are priority rules in order to determine whether a molecule is of the R-configuration or S-configuration. 1) Atoms with the higher atomic number have higher priority. For example, Nitrogen has a higher atomic number than Carbon so it gets priority. 2) If a decision cannot be reached (because both atoms attached to the central…
Suppose you have a gas that you can reliably assume is an ideal gas, and that there is only one species present. You know the mass of the sample, and you have it confined at a known pressure, volume, and temperature. What is the molecular weight of the unknown gas?
Adding or removing a product or reactant will shift the equilibrium of a reaction by Le Chatelier’s Principle. Adding or removing energy will have the same effect. Endothermic reactions take in energy, while exothermic reactions give off heat. Therefore, in an endothermic reaction, energy can be thought of as a reactant, and in an exothermic,…
When dealing with acid/base chemistry some of the quantities can seem difficult to comprehend and even redundant. Try your hand at some of these relations!
Molarity as well as the units that make up molarity are used indefinitely in chemistry, so fully understanding the concept is crucial. Some people do not realize that the idea of molarity extends past solutions and can be applied to pure substances (only the solvent). It is fun to get the science community thinking!
Gas law problems are very useful in everyday life, so it is nice to be able to navigate them and all their possibilities.
indian unioun for pure and applied chemistry its a full form of IUPAC its a general name of organic compound.
We are given mass in grams of a particular compound. We need to convert it into moles of that compound given the ratio formula and the masses of individual elements.
The Metric System is based on the fundamental units of measure for length, volume, and mass. Length: meter (m) Volume: liter (L) Mass : gram (g) Base units in the Metric System can be converted into units that are more appropriate for the quantity being measured by adding a prefix to the name of the…
