Answer: There are 20 carbons atoms, 62 oxygen atoms and 44 carbon atoms on the left side of the equation.
Explanation:
In the given chemical reaction:
[tex]2C_{10}H_{22}(l)+31O_2(g)\rightarrow 20CO_2(g)+22H_2O(g)[/tex]
Reactants side = Left side
Number of atoms =
Coefficient × Number of atoms of an element in a unit molecular formula
Number of carbon atoms = 2 × 10 = 20
Number of oxygen atoms = 31 × 2 = 62
Number of hydrogen atoms = 2 × 22 = 44
