(a)
Interpretation:
The terms ideal, actual, and percentage yield are to be distinguished in the scientific terms.
Concept introduction:
The conversion of the reactants to the products is called a reaction. The amount of product obtained from a reaction is known as yield. The extent of conversion of reactant to the product introduces the terms ideal and percentage yield.
(b)
Interpretation:
The terms limiting reactant, excess reactant are to be distinguished in the scientific terms.
Concept introduction:
The chemical equation of a reaction represents the stoichiometry with which the reactants are reacting with each other and stoichiometry of the product obtained with respect to that reaction.
(c)
Interpretation:
The terms heat of reaction, enthalpy of reaction are to be distinguished in the scientific terms.
Concept introduction:
The heat absorbed or given off from a reaction is known enthalpy of reaction. If the heat is absorbed than the enthalpy of reaction is taken a positive value. If the heat is given away then the enthalpy of reaction is taken as a negative value.
(d)
Interpretation:
The terms chemical equation, thermochemical equation are to be distinguished in the scientific terms.
Concept introduction:
The chemical equation is the representation of the
(e)
Interpretation:
The terms stoichiometry and thermochemical stoichiometry are to be distinguished in the scientific terms.
Concept introduction:
Stoichiometry is one of the very important parts of chemical equation problems. The stoichiometric ratio of the reactant and products is very useful in chemical equation problem-solving.
(f)
Interpretation:
The terms joule and calorie are to be distinguished in the scientific terms.
Concept introduction:
One calorie is defined as the amount of energy required to raise the temperature of one gram of water by one degree Celsius. A calorie is one of the units of energy just like joule. Joule is the SI unit of energy. The relation between a calorie and joule is

- Please correct answer and don't use hand rating and don't use Ai solutionarrow_forward1. For each of the following statements, indicate whether they are true of false. ⚫ the terms primary, secondary and tertiary have different meanings when applied to amines than they do when applied to alcohols. • a tertiary amine is one that is bonded to a tertiary carbon atom (one with three C atoms bonded to it). • simple five-membered heteroaromatic compounds (e.g. pyrrole) are typically more electron rich than benzene. ⚫ simple six-membered heteroaromatic compounds (e.g. pyridine) are typically more electron rich than benzene. • pyrrole is very weakly basic because protonation anywhere on the ring disrupts the aromaticity. • thiophene is more reactive than benzene toward electrophilic aromatic substitution. • pyridine is more reactive than nitrobenzene toward electrophilic aromatic substitution. • the lone pair on the nitrogen atom of pyridine is part of the pi system.arrow_forwardThe following reactions are NOT ordered in the way in which they occur.
