Mass of H₂ produced = 12 g
<h3>Further explanation</h3>
Given
32 grams of CH₄
Required
mass of H₂
Solution
Reaction
CH₄ + H₂O (+ heat) → CO + 3H₂
mol CH₄(MW= 16 g/mol) :
= mass : MW
= 32 g : 16 g/mol
= 2
From the equation, mol ratio CH₄ : H₂ = 1 : 3, so mol H₂ :
= 3/1 x mol CH₄
= 3/1 x 2
= 6
Mass H₂(MW = 2 g/mol) :
= mol x MW
= 6 x 2
= 12 g

A- The type of bread. some breads can become moldy faster than others.
B water and a little sugar because the sugar is going to stay there
Out of the choices given, the correct answer would be chlorine. It is the atom with the strongest attraction for electrons in a bond formation. This is because it has the highest electronegativity among the choices.
