Answer:
Proton & neutron
Explanation:
electrons only affect the charge. neutrons affect the mass and stability of an atom.
Four half lives have passed because the amount is cut in half each time
Answer:
When a solution of silver nitrate is added to a solution of sodium chloride, the silver ions combine with the chloride ions to form a precipitate of silver chloride. The sodium and the nitrate ions are nonparticipating spectator ions. ... Like all equations, net ionic equations must be balanced.

A- The type of bread. some breads can become moldy faster than others.
In the given heating curve, Particles of the substance have the most kinetic energy when the substance is (a) 1. A gas. The part of the graph that represents where the substance has the least amount of potential energy is labeled (b) 1. Solid.
<h3>What is Heating curve ?</h3>
The heating curve is the relationship between the heating system supply temperature and the outside air temperature.
Gas molecules have the highest average velocities among the three states of matter so gas has the highest kinetic energy.
During freezing, a substance loses a lot of potential energy so solid has the least potential energy.
Hence, In the given heating curve, Particles of the substance have the most kinetic energy when the substance is (a) 1. A gas.
The part of the graph that represents where the substance has the least amount of potential energy is labeled (b) 1. Solid.
