Answer:
Electrons
Explanation:
The breaking and forming of bonds between atoms in substances results in changes in the number of electrons in the substance.
- Atoms combined in order to share, gain or lose electrons for it to be stable.
- The noble gases have a set up configuration which makes them stable.
- All atom tend to mimic the noble gases.

Answer:
2.5 mL of 1.0 x 10⁻⁴ M solution needs to be added
Explanation:
M₁ (Molarity after dilution) = 1.0 x 10⁻⁵ M
V₁ (volume after dilution) = 25.0 mL
M₂ (molarity before dilution) = 1.0 x 10⁻⁴ M
dilution equation is written as M₁V₁ = M₂V₂
Making V₂ the subject of formula
V₂ = M₁V₁ / M₂
Substitute the parameters in the equation,
V₂ = 1.0 x 10⁻⁵ x 25.0 / 1.0 x 10⁻⁴
= 2.5 mL
Volume of the solution before dilution is 2.5 mL
Repeat same step for the next
A is the answer. A gas never has a fixed volume or shape
