The nuclear reactions involves the nuclei of the atoms, large amount of energy will be involved and some of the mass is converted into energy.

Explanation

Nuclear reactions are reactions which leads to change in the nuclei of the atoms.

The nuclear reaction occur between the nuclei of two atoms or between nuclei and other particles of two atoms.

The product formed will be different from the reactants.

The difference in the mass of the products and reactants are generally converted into energy.

In some nuclear reactions like nuclear fusion reaction, large amount of energy is required to collide the nuclei of two heavy elements to undergo nuclear chain reaction.

A nuclear to thermal and radiant

Explanation:

Nuclear fission is the disintegration of the force that holds the nucleus of the atom together, creating two different but lighter nuclei.

In nuclear fission, it seeks to break the force of attraction or nuclear force that joins the protons and neutrons that form the nucleus of an atom. Neutrons without electric charge are used against the nucleus of the atom to produce enough excitation energy to deform the nucleus into two halves.

Find the number of moles in 3.30 g of (NH4)2SO4?
Vesnalui [34]

Hey there!

Molar mass ( NH4)2SO4 =  132.1395 g/mol

So:

1 mole  ( NH4)2SO4 ---------------- 132.1395 g

moles (NH4)2SO4 ----------------- 3.30 g

moles (NH4)2SO4 = 3.30 * 1 / 132.1395

moles (NH4)2SO4 = 3.30 / 132.1395

=> 0.0250 moles of (NH4)2SO4

Answer A


Hope that helps!

PLEASE HELP MEEEEE!!!
ololo11 [35]

Answer:

Increasing temperature increases the solubility of most salts, but not all. The reason for the differences is that dissolution involves three steps: breaking bonds of salt in the lattice; forming cavities in water the same size as the ions; interacting the salt with water in the cavity.
