Question

_____ grams of hydrogen are required to react with 36 grams of carbon to form methane (CH4)​

Answer 1

In CH₄

2 H₂ is required to react with 1 Carbon

∴ 2 x 2 = 4 g of Hydrogen is required to react with 12 g of carbon

∴ Hydrogen required to react with 36 gram of Carbon

$\sf {{\dfrac {36}{12} \times 4 }} \\\\ \implies {\sf 3 \times 4 = 12~g}$

Answer 2

Answer:

12

Explanation:

Gram atomic mass of carbon=12 g

Gram atomuc mass of hydrogen = 1 g

or , 1 mole of CH⁴,so the carbon to hydrogen ratio is 12:4 i.e. 3:1.

3 grams of carbon require 1 gram of hydrogen gas to form methane .

so ,36 grams of carbon require .

36/3 × 1 = 12 g of hydrogen gas
