4 Fe (s) + 3 O2 (g) → 2 Fe2O3 (s)

How many moles of iron will react if 12 moles of oxygen gas reacts?

4Fe(s)+3O2(g)-->2Fe2O3(s)

How many moles of iron will react with excess amount of oxygen to form 3.00 moles of iron(III) oxide? How many moles of iron(III) oxide will be produced from 30.2 g of oxygen reacting with excess iron?

Fe2O3(molar mass=159.7 g/mol) reacts with CO(molar mass=28.0g/mol) according to the equationFe2O3(s)+3CO(g)>>>> 3CO2(g)+2Fe(s)
When 116g of CO reacts with excess Fe2O3, how many moles of iron will be produced?

1)Consider the decomposition of hydrogen peroxide into liquidwater and oxygen gas:

2 H202 (AQ) -> 2H20 (L) + 02 (G)

A) HOW MANY OF EACH OF THE PRODUCT MOLECULES WILL BE FORMED FROMTHE REACTION OF TWO DOZEN MOLECULES OF H202? 4 DOZEN?

B) HOW MANY OF THE PRODUCT MOLECULES WILL BE FORMED FROM THEREACTION OF 2 MILLION MOLECULES OF H202? 4 MILLION?

C) HOW MANY OF EACH OF THE PRODUCT MOLECULES WILL BE FORMED FROMTHE REACTION OF 2 MOLES OF H202? 4 MOLES? 15 MOLES?

D) WHAT IS THE RELATIONSHIP AMONG YOUR ANSWERS TO THE QUESTIONSABOVE? EXPLAIN WHY THIS RELATIONSHIP EXISTS.

2) BALANCE THE EQUATION C3H80 (L) + 02 (G) --> CO2 (G) + H20(G)

A) HOW MANY MOLES OF C3H80 WILL REACT WITH 2.500 MOLES OF OXYGENGAS?

BALANCE THE EQUATION FE (S) + 02 (G) --> FE203 (S)

A) HOW MANY MOLES OF IRON WILL REACT WITH 8.40 MOLES OF OXYGENGAS?
