Limiting reactants

Front

What is a limiting reactant?

Back

The reactant that determines how much product can be made.

Front

Use the equation 2 Al + 3 Cl2 -> 2 AlCl3. If 2 moles of aluminum and 2 moles of chlorine are reacted, identify the limiting reactant.

Back

Cl2

Front

What is the balanced equation for the reaction of sulfur dioxide and phosphorus pentachloride?

Back

SO2 + PCl5 -> SOCl2 + POCl3

Front

How do you determine the limiting reactant in a chemical reaction?

Back

By comparing the mole ratio of the reactants used in the balanced equation to the moles available.

Front

What is the molar mass of SO2?

Back

64.07 g/mol

Front

If you have 16.2g of SO2 and 13.7g of PCl5, how much SOCl2 is produced?

Back

7.87g

Front

What is the configuration for Carbon?

Back

1s2 2s2 2p2

Front

1s2 2s2 is which element?

Back

Beryllium

Front

What is the role of excess reactant in a chemical reaction?

Back

It is the reactant that remains after the limiting reactant is completely consumed.

Front

What happens to the limiting reactant during a chemical reaction?

Back

It is completely consumed when the reaction goes to completion.
