Answer:
A = 1.6
B = 3
Explanation:
When you are dividing exponents, you subtract them:
10^12 / 10^9 = 12 - 9 = 3
10³ would be the exponent
5.6/3.5 = 1.6
So, 1.6(10³) would be your answer.
1. A - atoms
2. B - protons electrons and neutrons

Answer: the chemical changes.
Explanation:
We understand by composition of a substance to the proportion (ratio or percentage) of each element (type of atoms) that makes up the same, as well as the way in which these elements are linked (chemical bonds).
A chemical change is a process, also called a chemical reaction, in which one or more substances are converted into different substances.
The resulting substances are different because their composition is different, since some chemical bonds have been broken and others have been formed, giving rise to a new structure. The chemical formula of each compound product of the chemical change will present a different combination of atoms, in ratio or structure.
The factors that limit a technological design can be physical and social. The physical limitations are constraints due to nature itself. They include natural laws and properties of materials.
Social limitations on the other hand are limitations that arise as a result of the society we are living in and include the ease of use, safety, attractiveness, and cost.
