Answers
Explanation:
a) limiting reactant
during the reaction when one reactant is consumed completely is known as limiting reactant .
b) molarity
it can be defined as the number of moles of his solute present in one litre of solution .
c) molality
it can be defined as the number of moles of solute present in 1 kg of solvent .
d) mole fraction
it can be defined as the ratio of moles of one component to the total number of moles present in the solution .
e) Precision and accuracy
closeness among the calculated result is known is precision while closeness to the actual value of a result is known as a Accuracy.
f) law of multiple proportion
according to this law when two elements combine to form two or more than two compounds then the different masses of an element which combines with the fixed mass of the Other element are in simple ratio of whole number .
g) gay lussac's law
according to this this law when the gases react to form the gaseous product they do show in the simple ratio of their volume .
