Answer:

Option D. 2. 19. 12. 14.

Explanation:

Look at the oxygens, which can be disbalanced. The other chioices does not balance the atoms so if we take account the last option we see that we have 38 atoms of O. 14 from water and 24 from CO2, so in reactant side it is logical to have 19 moles of O2 (the dyatomic molecule). In order to follow with C and H, we have 28 H and 12 C in both sides.

C3Hg + 02 → CO2 + H2O
fredd [130]

Answer:

4

Explanation:

The following equation, which depicts the combustion of propane, is given in this question as follows:

C3H8 + 02 → CO2 + H2O

However, this equation is not yet BALANCED because the number of atoms of each element is not the same on the reactant and product side. To balance the equation, we make use of COEFFICIENT to ensure that the number of atoms of each element on both side correlates.

The balanced equation is as follows:

C3H8 + 502 → 3CO2 + 4H2O

Therefore, the coefficient for water (H2O) after balancing the equation is 4.
