Answer:
Internal energy
Explanation:
Particles have two main energies that scientists acknowledge.
- The energy that is associated with their movement which we call kinetic energy. It is worth noting that particles have different kinetic energy, however the average kinetic energy that they have is directly proportional to temperature.
- The energy that is due to the interactive forces (attraction or repulsion) between particles is called potential energy
When these two types of energies are considered collectively, we call that internal energy
It would be polymer !!!!!
1. The formula of the hydrate is FePO₄•4H₂O
2. The name of the hydrate is Iron(iii) phosphate tetrahydrate.
1. Determination of the formula of the hydrate
- H₂O = 32.3%
- FePO₄ = 67.7%
- Formula =?
The formula of the hydrate can be obtained as follow:
Divide by their molar mass
H₂O = 32.3 / 18 = 1.794
FePO₄ = 67.7 / 151 = 0.448
Divide by the smallest
H₂O = 1.794 / 0.448 = 4
FePO₄ = 0.448 / 0.448 = 1
Therefore, the formula of the hydrate is FePO₄•4H₂O
The name of the hydrate is Iron(iii) phosphate tetrahydrate

The statement which is true about the reactivity of element with 1S²2S²2P⁶3S¹ is
it is reactive because it has to lose one electron to have a full outermost energy level.
<u><em>Explanation</em></u>
- <u><em> </em></u>Element with 1S²2S²2P⁶3S¹ electron configuration is a sodium metal.
- sodium has one electron in the outermost energy level.
- for sodium to have a full outermost energy level ( 8 electrons) it loses the 1 electron in 3S¹ to form a positively charged ion. (Na⁺)
