The acceleration on an object is proportional to the resultant force and inversely proportional to the mass of the object
<h3>Further explanation </h3>
Newton's 2nd law explains that the acceleration produced by <em>the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object </em>
∑F = m. a

F = force, N
m = mass = kg
a = acceleration due to gravity, m / s²
Newton's equation shows that the greater the net force applied to an object, the greater the acceleration, conversely the greater the mass of the object, the smaller the object's acceleration.

Answer:

Explanation:
You must convert the mass of B₄H₁₀ to moles of B₄H₁₀, then to molecules of B₄H₁₀, and finally to atoms of H.
1. Moles of B₄H₁₀

2. Molecules of B₄H₁₀

3. Atoms of H

In chemistry and physics, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
