Answer: -

Oxidation, Oxygen

Explanation: -

Burning of magnesium gives us magnesium oxide.

The chemical symbol of magnesium is Mg.

The chemical symbol of magnesium oxide is MgO.

So, the balanced chemical equation is

2Mg + O2 – 2 MgO.

We see that the element added is O Oxygen. So, the reaction is oxidation.

In oxidation always, oxygen is the common element involved in all chemical reactions of this kind.

The given reaction can be represented as,

2Mg (s) + O_{2}(g) ---> 2MgO (s)

In this reaction, two elements (Mg and O_{2}) combine to form a single compound, MgO. Hence, this reaction is an example of chemical combination or synthesis. Here as the element Mg is oxidized in the presence of O_{2} to form MgO. This is referred to as combustion reaction. In combustion reaction, elements or compounds react with oxygen to give their respective oxides.

What is the value of n?
Softa [21]
M = n/V

M = 1.51
V = 0.730

1.51 = n/0.730

To solve this, multiply both sides by the V.

1.1023 = n

n = 1.1023 mol

Not all of the water falls as rain, snow,or sleet evaporates. What happens to the rest of the water?
Bumek [7]
Hi there! All of the water returns to the atmosphere, it's called evapotranspiration and condenses. And then the water falls back to the Earth's surface and starts the cycle all over again. If you don't know what I mean, it's the Water Cycle.

What do you think might be different between fat molecules and carbohydrate and protein molecules?
dimulka [17.4K]

Answer:

Long answer

Proteins are the building blocks of the body, each and every organ muscle and skin and cells are made of proteins. They can also be used for providing energy to the body in a state where other energy sources aren't available.

Fats are stored energy blocks which can be used by the body at its own convenience whenever there is a deficit of energy in the body. They can also be directly burnt to give energy in cases where energy needs of the body are not met by dietary intake

Carbohydrates are the most convenient and preferable source of energy in the body and are easily converted to give out immidiate energy to the body, excess carbohydrates can be converted into fats and stored for later usage as and when required by the body.

Proteins, fats and carbohydrates have many secondary functions and roles in the human body. If you are keen to know anything more specific feel free to ask.

<h3>Short answer :</h3>

Fats are used for energy after they are broken into fatty acids. Protein can also be used for energy, but the first job is to help with making hormones, muscle, and other proteins.
