Molar mass:

O₂ = 16 x 2 = 32.0 g/mol    

C₃H₈ = 12 x 3 + 1 x 8 = 44.0  g/mol

Balancing chemical equation :

<span>C</span>₃<span>H</span>₈<span>+ 5 O</span>₂<span> = 3 CO</span>₂<span> + 4 H</span>₂<span>O
</span>
44.0 g C₃H₈ ------------- 5 x 32.0 g O₂
94.4 g C₃H₈-------------- ( mass of O₂)

mass of O₂ = 94.4 x 5 x 32.0 / 44

mass of O₂ = 15104 / 44

= 343.27 g of O₂

hope this helps!

Minchanka [31]

Answer:

The acid will be neutralized overtime

Explanation:

The presence of the pyrites leads to the leaching of large amounts of sulphuric acid, however the basic carbonates neutralizes the acid according to the reaction equation;

CaCO3 + H2SO4 ---> CaSO4 + CO2 + H2O.

This will prevent all the deleterious consequences associated with the leaching of the acid in the abandoned coal mine.
