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.
Balancing of chemical equation is essential because of the law of conservation of mass, which states that the mass of a system can not be created or removed.
The second equation is balanced
This is because the number of elements of each atom in the product side equal the number of elements of each atom on the reactant side.
The first equation is not balanced
This is because there is 1 molecule of on reactant side as compared to 3 molecules of
To balance the equation we add a coefficient of 3 on sulphuric acid () and a coefficient of 3 on hydrogen (
)
