What would be the immediate product of neutron absorption by Ag 107
Novosadov [1.4K]

The immediate product of neutron absorption by Ag-107 is silver atom with a mass of 108, Ag-108.

<h3>What is radioactivity?</h3>

Radioactivity is the spontaneous emission of radiation as wall as particles and energy l by the nucleus of elements due to their disintegration.

The radioactive particles that are usually emitted include:

  • alpha particles
  • beta particles and
  • neutrons

The neutron has a mass of 1.

When silver isotope having a mass of 107 absorbs a neutron, the silver isotope produces will have a mass of 108, Ag-108.

What is this balanced?<br> Al2O3---&gt; Al+O2
saveliy_v [14]

The balanced equation :

<em>2Al₂O₃⇒ 4Al+3O₂</em>

<h3>Further explanation</h3>

Given

Reaction

Al₂O₃⇒ Al+O₂

Required

Balanced equation

Solution

A chemical reaction is said to be balanced if the number of elements involved in the reaction is the same (either the reactants or the products)

The reaction above is said to be unbalanced because the number of elements Al and O in the reactants and products is not the same.

The balancing step

1. Give a coefficient

Al₂O₃⇒ aAl+bO₂

2. Make an equation

Al, left = 2, right = a⇒a=2

O, left = 3, right = 2b⇒2b=3⇒b=3/2

The equation becomes :

Al₂O₃⇒ 2Al+3/2O₂ x2

<em>2Al₂O₃⇒ 4Al+3O₂</em>
