Question

Given:

CH4+2O2 - CO2 + 2H2O

in chemical reaction, if 10 moles of H2O are produced, ___?___ moles of CO2 are also produced.

Answer 1

it depends on what kind of reaction it is. it could be 10 moles too, but it can be less, for example, if the products looked like this
CO2+2 H2O the answer would be:

x mol CO2 - 10 mol H20
1 mol CO2 - 2 mol H2O


`x = (1 * 10)/(2) = 5 \: mol`
