Problem
Carbon dioxide is produced according to the reaction below.
ZnO + CO ➞ Zn + CO2 (Eq 1)
The carbon monoxide used above is prepared from
2C + O2 ➞ 2CO (Eq 2)
If 87.5 g of C reacts with excess of oxygen gas, and ZnO is in excess, how many grams of Zn can be obtained?
This problem can be solved by any of the strategies below.
Strategy 1
Calculate moles of CO produced on Eq 2 ➡ go to Eq 1 and determine moles of Zn ➡ calculate grams of Zn
Strategy 2 Determine the net chemical equation for the production of Zn ➡ determine moles of Zn ➡ calculate grams of Zn
Click here for details about how to find the net chemical equation.
