Answer: 7.98 grams of
are produced if 10.7 grams of
are reacted.
Explanation:
To calculate the number of moles, we use the equation:
.....(1)
Putting values in equation 1, we get:
The chemical equation for the reaction is
By Stoichiometry of the reaction:
2 moles of
produce = 1 mole of
So, 0.100 moles of
produce=
of
Mass of
=
Hence 7.98 grams of
are produced if 10.7 grams of
are reacted.
6g of hydrogen gas is my answer. I'm sorry if I'm wrong.
