Chemical Reactions and Stoichiometry

Front

What is a chemical reaction?

Back

A chemical reaction is a process in which substances (reactants) are transformed into different substances (products) through the breaking and forming of chemical bonds.

What is stoichiometry?

Back

Stoichiometry is the calculation of reactants and products in chemical reactions based on the conservation of mass and the mole concept.

Define limiting reagent.

Back

The limiting reagent is the reactant that is completely consumed in a chemical reaction, limiting the amount of product that can be formed.

Front

What is theoretical yield?

Back

Theoretical yield is the maximum amount of product that can be produced from a given amount of reactants, calculated based on stoichiometric ratios.

How do you calculate moles from grams?

Back

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

What is the molar mass of potassium (K)?

Back

The molar mass of potassium (K) is approximately 39.10 g/mol.

Front

What is the molar volume of a gas at STP?

Back

The molar volume of a gas at standard temperature and pressure (STP) is 22.4 L.

Front

How do you determine the limiting reagent in a reaction?

Back

To determine the limiting reagent, calculate the moles of each reactant and compare the mole ratios required by the balanced equation.

What is the balanced equation for the combustion of butane (C4H10)?

Back

The balanced equation for the combustion of butane is: @@2 ext{C}_4 ext{H}_{10} + 13 ext{O}_2 ightarrow 8 ext{CO}_2 + 10 ext{H}_2 ext{O}@@.
