Answer:
If the color of the light in the environment changes, then the number of light red kidney beans increases because the red light makes the light red kidney beans more difficult to see.
Explanation:
Just did it this is the sample answer
- C2H4 + H20 --> C2H5O
- <span>C3H8 + Cl2--> C3H7Cl +HCl
- </span><span>C2H2+Br2 --> C2H2Br2</span>
- C4H10+Br2 --> C4H10+HBr
- <span>C3H6 + BR2 --</span>> C3H6BR2
Answer:
b. Two moles of thiosulfate anion needed to react with one mole of hypochlorite anion.
Explanation:
1. Hypochlorite with iodide
2I⁻ ⟶ I₂ + 2e⁻
<u>ClO⁻ + 2H⁺ + 2e⁻ ⟶ Cl⁻ + H₂O </u>
2I⁻ + ClO⁻ + 2H⁺ ⟶ I₂ + Cl⁻ + H₂O
2. Thiosulfate with iodine
2S₂O₃²⁻ ⟶ S₄O₆²⁻ + 2e⁻
<u> I₂ + 2e⁻ ⟶ 2I⁻ </u>
2S₂O₃²⁻ + I₂ ⟶ S₄O₆²⁻ + 2I⁻
3. Sum of the reactions
2I⁻ + ClO⁻ + 2H⁺ ⟶ I₂ + Cl⁻ + H₂O
<u> 2S₂O₃²⁻ + I₂ ⟶ S₄O₆²⁻ + 2I⁻ </u>
2I⁻ + ClO⁻ + 2S₂O₃²⁻ + 2H⁺ ⟶ I₂ + Cl⁻ + S₄O₆²⁻ + H₂O
4. Molar ratio
S₂O₃²⁻:ClO⁻ = 2:1
