Concept explainers
(a)
Interpretation: To write the balanced chemical equation for the reaction.
Concept Introduction:
Chemical equation is way of representing the
To the reaction arrow, reactants are always on the left-hand side and products on the right-hand side.
(b)
Interpretation: To determine the mass of O2 required to react with 2.50 g of H2S.
Concept Introduction:
A
Let’s say we have a chemical reaction as:
If above reaction is well-balanced then,
‘a’ moles of A reacts with ‘b’ moles of B to produce ‘c’ moles of C and ‘d’ moles of D.
(c)
Interpretation: To determine the mass of SO2 produced from 38.5 g of O2.
Concept Introduction:
A stoichiometric coefficient of a well-balanced chemical equation tells about the relative relation between moles of reactants used and moles of products formed.
