Answer:
15.9 grams of copper is produced
Explanation:
Step 1: Data given
Volume of hydrogen = 5.60 L ( at STP)
Step 2: The balanced equation
CuO (s) + H2 (g) → Cu (s) + H2O (g)
Step 3: Calculate moles H2
22.4 L = 1 mol
5.60 L = 0.25 moles
Step 3: Calculate moles Cu
For 1 mol CuO we need 1 mol H2 to produce 1 mol Cu and 1 mol H2O
For 0.25 moles H2 we'll have 0.25 moles Cu
Step 4: Calculate mass Cu
Mass Cu = moles Cu * molar mass Cu
Mass Cu = 0.25 moles * 63.546 g/mol
Mass Cu = 15.9 grams
15.9 grams of copper is produced

I believe in what USA was and is able to achieve, and trust the nation in many but every ways. What really made it a developed nation is the things that happened in the last 3 Centuries, some of which are;
#1 CULTURAL TOLERANCE & IMMERSION
#2 TECHNOLOGICAL INVENTIONS & ADVANCEMENT IN THE FIELD OF SCIENCE
#3 FAST FOOD CULTURE
#4 HOLLYWOOD
#5 INTEGRITY & PATRIOTISM
#6 MASS CONSUMERISM
