It would be a gas because gases have the highest amount of kinetic energy and takes the shape/volume of it's container.
Hope this helps(;
It has a decrease in oxidation number
The process of reduction is when the oxidation number of a chemical specie is lowered, or when the specie gains electrons. A chemical specie undergoing reduction will act as an oxidizing agent, because it will oxidize the other reactant by itself getting reduced.
The electrons in an atom that are in orbits away from the nucleus are called valence electrons. Nitrogen: 5, Silicon: 4, Oxygen: 6, Magnesium: 2.
<h3>What exactly is a positive electron and why is it significant?</h3>
Valence electrons are the electrons that reside in an atom's outermost shell. The role of valence electrons in controlling an atom's reaction makes them crucial. By writing an octet, you'll be enabled see how many protons fill the highest amount of energy.
<h3>What is valence defined simply?</h3>
In chemistry, valence, sometimes called valency, is a characteristic of an element who establishes how many other atoms of the element each atom can interact with. The phrase, which was first used in 1868, is used to represent both the broad capability of pairing of an element and its numerical value.

25.9 kJ/mol. (3 sig. fig. as in the heat capacity.)
<h3>Explanation</h3>
The process:
.
How many moles of this process?
Relative atomic mass from a modern periodic table:
- K: 39.098;
- N: 14.007;
- O: 15.999.
Molar mass of :
.
Number of moles of the process = Number of moles of dissolved:
.
What's the enthalpy change of this process?
for . By convention, the enthalpy change measures the energy change for each mole of a process.
.
The heat capacity is the least accurate number in these calculation. It comes with three significant figures. As a result, round the final result to three significant figures. However, make sure you keep at least one additional figure to minimize the risk of rounding errors during the calculation.
When you consume proteins, carbs, and fats they are chemically changed into energy.
