Elements from 57 to 71 are Lanthanoids and from 89 to 103 are Actinoids. Simply I would say Actinoids have less similarity in chemical properties than Lanthanoids. On the other hands, Actinoids have randomized chemical strutural bonds.

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.

The final solution had a volume of 1.0L and a molarity of 0.925. How many moles of Nickel (II) chloride were present in the solu
Llana [10]

Answer:

0.925 moles of Nickel (II) chloride

Explanation:

Now, we know that the number of moles in a solution is given by;

n=CV

n= number of moles

C= molar concentration of solution = 0.925 M

V= volume of solution= 1.0 L

So having known all the parameters except the unknown (number of moles of Nickel (II) chloride) we can now proceed to find the unknown.

n= 0.925M ×1.0L

n= 0.925 moles of Nickel (II) chloride
