Chapter 4 - Stoichiometry Flashcards
1
Q
What information do balanced chemical equations provide?
A
- The reactants/reagents
- The products
- The physical states
- The number of molecules or atoms
- The moles (reactant atoms) / moles (product atoms)
- The grams of the reactants / products
2
Q
What is stoichiometry?
A
Calculating quantities of reactants and products in a chemical reaction
- Stoichiometry is based on the Law of Conservation of Matter
3
Q
What can the amount of another substance in a chemical reaction be determined by?
A
It can be determined from the amount of just one substance
4
Q
What is theoretical yield?
A
Calculated - the maximum amount of product that can form during a reaction
5
Q
What is actual yield?
A
Observed - the amount of product physically isolated
6
Q
How do you solve for percent yield
A
Percent yield = actual yield / theoretical yield x 100%
