Answer:
Explanation:
Potassium ion will be formed when potassium atom loses one electron to become positively charged
K₁₉ →→ K₁₉⁺ + e⁻
Bromine ion is formed by gain of electron
Br₃₅ + e⁻ → Br₃₅⁻
A. fusion
A fusion reaction is when two smaller molecules join to form a larger molecule and energy is relased

Answer:
A. Chemical
- AA battery contains chemical energy
Answer:
The correct option is: A. 0.168 M
Explanation:
Chemical reaction involved:
5 Fe²⁺ (aq) + MnO₄⁻ (aq) + 8 H⁺ (aq) → 5 Fe³⁺ (aq) + Mn²⁺ (aq) + 4 H₂O
Given: <u>For MnO₄⁻ solution</u>-
Number of moles: n₁ = 1, Volume: V₁ = 20.2 mL, Concentration: M₁ = 0.0250 M;
<u>For Fe²⁺ solution</u>:
Number of moles: n₂ = 5, Volume: V₂ = 15 mL, Concentration: M₂ = ?M
<u><em>To find out the concentration of Fe²⁺ solution (M₂), we use the equation:</em></u>




<u>Therefore, the concentration or molarity of Fe²⁺ solution: </u><u>M₂ = 0.168 M</u>
