Mass of liquid reactant A is 11g.
as we know that,
reactant = product
from conservation of mass
so, liquid reactant A + liquid reactant B = liquid product + solid product
substituting the values, we get,
liquid reactant A + 9 = 8 + 12
liquid reactant A + 9 = 20
liquid reactant A = 20 - 9
liquid reactant A = 11g
Hence, mass of the liquid reactant A is 11g.
what is a reactant ?
A reagent, also known as an analytical reagent, is a substance or compound that is added to a system in chemistry to bring about a chemical reaction or check to see whether one happens. Although the terms "reagent" and "reactant" are frequently used synonymously, "reactant" refers to a material that is consumed during a chemical reaction.
