Stoichiometry gas problems involves different categories and also involve gas stoichiometry, but the approach used same. There is a step-by-step way of solving stoichiometry problems which is still the same for stoichiometry involving gases. What’s gas stoichiometry? Gas stoichiometry is the simply the particular stoichiometry concept that deals with gases in a balanced chemical equation….
There are certain pieces of apparatus in used in chemistry laboratory that we need to always remember their structure and uses. This is very important because it will enable us to properly function well in the laboratory. So i have laid down the tabular form of the uses of pieces of apparatus and their descriptions….
Stoichiometry problems involving mole to mole calculations by using balanced chemical equations to determine the amount of one substance (in moles) required to react with a certain amount of another substance (also in moles). In addition, every stoichiometry problem can be solved from the angle of mole-to-mole stoichiometry problem tips. In mole-to-mole stoichiometry, there is need to…
Mole ratio in Stoichiometry is basically the guiding principle used in calculating Stoichiometry problems. It is important to recall that mole concept is the Stoichiometry principle used in calculating Stoichiometry questions. Moreover, in calculating stoichiometry problems you need to first relate the use the mole ratio and then be able to compare the substances and…
A reaction could occur very fast or very slowly depending on a lot of factors like temperature, pressure, concentration etc. It is pertinent to understand the basic chemistry of Chemical Kinetics Rate of reaction is defined as the amount of reactants converted to products per unit time.During a chemical reaction, the amount of reactants decreases…
What is quantum chemistry? Quantum chemistry is the branch of theoretical chemistry that applies quantum mechanics to study the behavior and properties of sub-particles of an atom, especially the electron. What is an orbital? An orbital is a region where there is a high probability of finding an electron. There are basic principles that determine…
Hints on how to calculate the theoretical yield of products are essential and can’t be over-emphasized due to the errors students do in exams. Theoretical yield is the amount of product based on stoichiometry calculation while the experimental yield (practical yield) is the amount of product gotten from the experiment. Actually, to get the theoretical…
How to to deduce the valency of elements? To deduce the valency of elements, there is a need to understand the atomic numbers of elements if we can really predict the valency of elements. Valency is the number of electrons gained or lost in order to form ions. Valence electrons can be deduced from the…
Cambridge IGCSE Chemistry guide has a lot of specifics commonly used in Cambridge Chemistry. The terms used in Cambridge Chemistry have proper definitions. These definitions are commonly used in Cambridge IGCSE Chemsitry. 1. Define the term proton number: The number of protons in the nucleus of an atom 2. Define the term acid: A proton…
What is true about all uranium atoms? Uranium is an element that has some specifics or special properties for example it was the first element used by Alert Einstein in the nuclear bomb production. Yes, it is radioactive but is that all we know about uranium atoms? Not really, I am going to show you…
