Question

List the number of each type of atom on the left side of the equation C5H12(g)+8O2(g)→5CO2(g)+6H2O(g) C 5 H 12 ( g ) + 8 O 2 ( g ) → 5 C O 2 ( g ) + 6 H 2 O ( g ) Enter your answers separated by commas (the order of the numbers is the same as the order of the elements on the left side of the equation).

Answer 1

Answer:

Carbon=5, hydrogen=12, oxygen=16

Explanation:

Carbon=5, hydrogen=12, oxygen=16

In order to effectively count the number of atoms, we look at the equation closely and take note of the stoichiometric coefficients of each reactant as this influences the number of atoms of that element present.

For instance, oxygen is diatomic and has a stoichiometric coefficient of 8. This implies the there are sixteen atoms of oxygen altogether.

Note that the left hand side refers to the reactants side.

Answer 2

Answer:

Explanation:

Equation of the reaction:

C5H12(g) + 8O2(g) → 5CO2(g) + 6H2O(g)

1. Ensure the equation of the reaction is balanced properly.

2. Pick any side of the reaction a d List the atoms present.

Carbon, C = 5 atoms

Oxygen, O = (8 × 2)

= 16 atoms

Hydrogen, H = 5 atoms
