Concept explainers
(a)
Interpretation:
Product formed by
Concept Introduction:
Nuclear reaction: A nuclear reaction in which a lighter nucleus fuses together into new stable nuclei or a heavier nucleus split into stable daughter nuclei with the release of large amount of energy.
Balancing nuclear reaction equation: The balanced nuclear reaction should conserve both mass number and atomic number.
- The sum of the mass numbers of the reactants should be equal to the sum of mass numbers of the products in the reaction.
- The sum of
atomic numbers (or the atomic charge) of the reactants should be equal to the sum of atomic numbers (or the atomic charge) of the products in the reaction.
(b)
Interpretation:
The process that releases more energy has to be determined using given information.
Concept Introduction:
Nuclear binding energy: It is the energy that requires for the breaking one mole of nuclei of an element to its individual nucleons.
It can be calculated using the given formula,
Change in mass of a given reaction can be determined as given,

- 1. 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.
