Consider the following reaction: 3NO 2 ( g ) + H 2 O( l ) ? 2HNO 3 ( l ) + NO( g

Question

Consider the following reaction:
3NO2(g) + H2O(l) ? 2HNO3(l) + NO(g)
How many moles of NO2 are required to react with 1.50 moles of H2O to form 3.00 moles of HNO3? Answer                              A. 3.00 mol                 B. 9.00 mol                 C. 1.50 mol                 D. 4.50 mol                 E. 4.00 mol Consider the following reaction:
3NO2(g) + H2O(l) ? 2HNO3(l) + NO(g)
How many moles of NO2 are required to react with 1.50 moles of H2O to form 3.00 moles of HNO3? 3.00 mol 9.00 mol 1.50 mol 4.50 mol 4.00 mol                 A. 3.00 mol                 B. 9.00 mol                 C. 1.50 mol                 D. 4.50 mol                 E. 4.00 mol

Explanation / Answer

3NO2(g) + H2O(l) ------ > 2HNO3(l) + NO(g)

3moles of NO2 produce 2 moles of HNO3
moles of NO2 req=(3/2)*3= 4.5 moles

option D is correct
