In the following equation, how many atoms of oxygen are in the products?
C2H8 + 4 O2 → 2 CO2 + 4 H2O
a
8
b
6
c
4
d
2
The number of oxygen atoms in the products is given by the coefficient in front of CO2 and H2O. In this equation, the coefficient in front of CO2 is 2, and the coefficient in front of H2O is 4.
So, there are 2 oxygen atoms in CO2 and 4 oxygen atoms in H2O.
Therefore, the total number of oxygen atoms in the products is 2 + 4 = 6.
The correct answer is b) 6.
