Question

What is the value of delta ng
CH4 2O2gives CO2 2H2O

Answer 1

Answer:

-2

Step-by-step explanation:

∆ng = no. of moles of gaseous products - no. of moles of gaseous reactants.

In this ques, gaseous products is CO2 (not H2O)

and gaseous reactants are CH4 and O2.

∆ng = 1-(1+2)

=1-3 = -2
