Unit 10: Stoichiometry Escape Room Blizzard

Front

What is stoichiometry?

Back

Stoichiometry is the branch of chemistry that deals with the calculation of reactants and products in chemical reactions based on the conservation of mass.

Front

What is the molar mass of a compound?

Back

The molar mass of a compound is the mass of one mole of that compound, typically expressed in grams per mole (g/mol).

Front

How do you convert grams to moles?

Back

To convert grams to moles, use the formula: Moles = Mass (g) / Molar Mass (g/mol).

Front

What is the balanced equation for the combustion of glucose (C6H12O6)?

Back

C6H12O6 + 6 O2 → 6 CO2 + 6 H2O.

Front

How many moles of CO2 are produced from 1 mole of C6H12O6?

Back

6 moles of CO2 are produced from 1 mole of C6H12O6.

Front

What is the stoichiometric ratio?

Back

The stoichiometric ratio is the ratio of the coefficients of reactants and products in a balanced chemical equation.

Front

How do you determine the limiting reactant in a reaction?

Back

To determine the limiting reactant, calculate the number of moles of each reactant and compare the mole ratios from the balanced equation.

Front

What is the molar mass of O2?

Back

The molar mass of O2 is 32.00 g/mol.

Front

How many grams of KCl can be produced from 2 moles of KBr?

Back

From the reaction Cl2 + 2KBr → Br2 + 2KCl, 2 moles of KBr produce 2 moles of KCl.

Front

What is the molar mass of KBr?

Back

The molar mass of KBr is approximately 119.00 g/mol.
