Answer:
MnO- Manganese Oxide
Explanation:
Empirical formula: This is the formula that shows the ratio of elements
present in a
compound.
How to determine Empirical formula
1. First arrange the symbols of the elements present in the compound
alphabetically to determine the real empirical formula. Although, there
are exceptions to this rule, E.g H2So4
2. Divide the percentage composition by the mass number.
3. Then divide through by the smallest number.
4. The resulting answer is the ratio attached to the elements present in
a compound.
Mn O
% composition 72.1 27.9
Divide by mass number 54.94 16
1.31 1.74
Divide by the smallest number 1.31 1.31
1 1.3
The resulting ratio is 1:1
Hence the Empirical formula is MnO, Manganese oxide

Almost all fusion taking place in the Sun is hydrogen fusing to helium, So A Helium-4 I think that the best choice.
You are only allowed to Add coefficients
Answer:
A chemical reaction can release chemical energy stored in batteries, natural gas, and even coal. The main advantage of chemical energy is that it is abundant in nature. Chemical energy can be produced by many organic materials.
