<h3>What is scientific knowledge?</h3>
The process by which scientists obtain information and establish knowledge is;
Observation ---> hypothesis ------> experiments ------> Theory -------> Law.
Thus after the process of observation what we have is merely a scientific hypothesis that needs to pass through the process of rigorous experimentation before it is proven to be true.
Thus the words that complete the blanks are hypothesis and experimentation.

The general properties of matter result from its relationship with mass and space. ... Because it occupies space, all matter has volume and impenetrability, since two objects cannot occupy the same space simultaneously.
The answer is Thermal Energy :)
Answer:
The change in concentration of H+ ions is -9.99×10⁻⁵
Explanation:
When pH rises, we talk about neutralization and, there is a decline in proton's concentration.
pH lower than 7 is acid
pH higher than 7 is basic
Protons are neutralized by hydroxides to make water as this:
H₃O⁺ + OH⁻ ⇄ H₂O
pH = - log [H₃O⁺]
[H₃O⁺] = 10^-pH
In conclussion: [H₃O⁺]₁ = 10⁻⁴ → 1×10⁻⁴
[H₃O⁺]₂ = 10⁻⁷ → 1×10⁻⁷
1×10⁻⁷- 1×10⁻⁴
The change in concentration of H+ ions is -9.99×10⁻⁵
