As early as 1938, the use of NaOH was suggested as a means of removing CO2 from the cabin of spacecrafts according to the unbalanced reaction:
NaOH+CO_2->Na_2CO_3+H_2O
This is the number of moles of NaOH needed to react with the average daily CO2 discharge of a person, 925.0 g CO2.
What is 42.04 mol NaOH?
2NaOH+CO_2->Na_2CO_3+H_2O
925.0g CO_2*(1 mol CO_2)/(44.01g CO_2)*(2 mol NaOH)/(1 mol CO_2)=42.04 mol NaOH

Coal gasification is a process that converts coal into methane gas(CH4) by the following reaction:
2C(s)+2H_2O(l)->CH_4(g)+CO_2(g)
If 710. g of methane is actual produced, this is the percent yield given that 1250 g of carbon were reacted.
What is 85.0%?
1250 g C*(1 mol C)/(12.01 g C)*(1 mol CH_4)/(2 mol C)*(16.05 g CH_4)/(1 mol CH_4)= 835g CH_4
710/835*100=85%

If 2.50 mol Cu and 5.50 mol of AgNO3 react by single replacement, this is the limiting reactants and the moles of each product formed.
Please use Copper(ii) when determining the formulas for the products
What is Cu and 2.50 mol Cu(NO3)2 and 5.00 mol Ag?
Cu+2AgNO_3->Cu(NO_3)_2+2Ag
2.50 mol Cu/1 = 2.5
5.50 mol AgNO_3/2=2.75
Limiting reactant is Cu
2.50 mol Cu*(1 mol Cu(NO_3)_2)/(1 mol Cu)=2.50 mol Cu(NO_3)_2
2.50 mol Cu*(2 mol Ag)/(1 mol Cu)=5.00 mol Ag
