Answer:
Heating a substance increases the speed at which molecules move.
Explanation:
C. The law that was used to determine the relationship between the volume and the number of moles is Avogadro’s law.
<h3>What is Avogadro’s law?</h3>
Avogadro's law states that equal volumes of any gas contain the same number of molecules at the same temperature and pressure.
V ∝ n
where;
- V is volume of the gas
- n is number of moles
Thus, the law that was used to determine the relationship between the volume and the number of moles is Avogadro’s law.

Explanation:
NH₄F+ AICI₃, → NH₄CI + AlF₃
NH,F: in ionic form
NH₄⁺ + F⁻ = NH₄F
AICI in ionic form:
Al³⁺ + Cl⁻ = AlCl₃
NH Cl in ionic form:
NH₄⁺ + Cl⁻ = NH₄Cl
Al F in ionic form:
Al³⁺ + F⁻ = AlF₃
NH₄F+ AICI₃, → NH₄CI + AlF₃
Now we have to balance the equation with respect to the atoms:
aNH₄F+ bAICI₃, → cNH₄CI + dAlF₃
for N: a = c
H: 4a = 4c
F: a = 3d
Cl: 3b = c
let a = 1
c = 1
b =
d =
Therefore we can imply that:
a = 3, b = 1 , c = 3 and d = 1 if we multiply through by 3
3NH₄F+ AICI₃, → 3NH₄CI + AlF₃

Answer: 28.4 g of aluminum oxide is produced by the reaction of 15.0 g of aluminum metal
Explanation:
To calculate the moles :
The balanced chemical equuation is:
According to stoichiometry :
4 moles of produce == 2 moles of
Thus 0.556 moles of will produce= of
Mass of
Thus 28.4 g of aluminum oxide is produced by the reaction of 15.0 g of aluminum metal.
