What is the ration of H2O:O2? 2H2 + O2 → 2H 20

Explanation:

What are the mole ratio and the mass ratio for H2O to O2 in the reaction 2H2 + O2 → 2H2O? Mole ratio of H2O to O2 in the given reaction is H2O : O2 = 2 : 1. Mass ratio of H2O to O2 in the given reaction is H2O : O2 = 36 : 32 = 1 : 1.1.

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year

i think that the answer is c
