Answer:
The standard potential, E cell, for this galvanic cell is 0.5670V
Explanation:
Ni²⁺(aq) + 2e⁻ → Ni(s) E red = - 0.23V ANODE
Cu²⁺(aq) + 2e- → Cu(s) E red = + 0.337V CATHODE
ΔE° = E cathode - E anode
ΔE° = 0.337V - (0.23V) = 0.5670 V
Sodium reacts with water to form a colorless solution of sodium hydroxide and hydrogen gas.
Answer:
Breaker A
Explanation:
Because the temperature is cooler in A then the rest
This might be wrong,but im pretty sure its 0.10 m
