give me full notes on stoichiometry
Answers
Answer:
Introduction:
Basically, the stoichiometry may be regarded as the branch of chemistry and chemical engineering which deals with the quantities of substances which enter into and are produced by chemical reactions. Stoichiometry gives the quantitative relationship between reactants and products in a chemical reaction. It can be utilized in microbial technology also.

Introduction:
Basically, the stoichiometry may be regarded as the branch of chemistry and chemical engineering which deals with the quantities of substances which enter into and are produced by chemical reactions. Stoichiometry gives the quantitative relationship between reactants and products in a chemical reaction. It can be utilized in microbial technology also.
Stoichiometry can be classified into two main categories:
ADVERTISEMENTS:
1. Composition Stoichiometry:
Deals with mass relationships of elements in compounds
2. Reaction Stoichiometry:
Involves mass relationships between reactants and products in a chemical reaction
ADVERTISEMENTS:
In ideal Stoichiometry – All reactants are converted into products.
Common Methods for solving all Stoichiometry Problems:
Mass-Mass Problems:
1. Start with a known mass of reactant or product and find an unknown mass of another reactant or product.
2. All other stoichiometry problems are derivations (shortened versions) of this larger solution:
Steps for solving problems:
1. Start with a correctly balanced chemical equation.
2. Use key words in the problem statement to identify substances as either reactants or product
3. Determine what units you’ve been given and what you are being asked to find.
4. Label each step with the correct units the units from the numerator of the first step become the units in the denominator of the next step, and so forth.
5. Stop when you have an answer with the units that you are searching for.
