On what law is stoichiometry based, and how do the calculations support this law?

Answer 1

#"Garbage in equals garbage out."#

See this old answer and links.

Every chemical reaction that HAS EVER BEEN PERFORMED obeys conservation of mass. You start with #1*g#, #10*g#, #1*kg#, #10*"tonnes"# of reactant from all sources and at most you are going to get #1*g#, #10*g#, #1*kg#, #10*"tonnes"# of product.

In practice, you are not even going to get that. Losses invariably occur on handling. And note that this is an experimental result, that is rationalized by our particle view of chemical reactivity. We don't have to rely on calculations; we do have to rely on experiment.

Answer 2

Stoichiometry is based on the law of conservation of mass. The calculations involve balancing chemical equations and using mole ratios to determine the quantitative relationship between reactants and products in a chemical reaction, ensuring that mass is conserved. The mole ratios derived from balanced equations are crucial for converting between reactants and products in stoichiometric calculations.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
