Answer:
The potential wrt. calomel is 1.254 V
Explanation:
Given:
Potential wrt. silver chloride
V
Potential wrt. saturated silver chloride
V
Potential wrt. SCE
V
Now potential wrt. hydrogen is given by,
V
And we find for potential wrt. calomel,
potential wrt. hydrogen + potential wrt. SEC

V
Therefore, the potential wrt. calomel is 1.254 V
Answer:
energy
Explanation:
Those are all forms of energy
3NF3 + 5H2O → HNO3 + 2NO + 9HF
Nitrogen fluoride reacts with water to produce nitric acid, nitric oxide, and hydrogen fluoride. The reaction slowly takes place in a boiling solution.
CH2CH2 + H2O → CH3CH2OH
Ethylene is a hydrocarbon with water that creates ethanol and ethanol is an alcohol
Answer:
mass PbI₂ formed = 1383 grams
Explanation:
Pb(NO₃)₂ + 2NaI => 2NaNO₃ + PbI₂(s)
6 mol NaI => 1/2(6 mol) PbI₂ = 3 mol PbI₂ x 461.01 g/mol = 1383.03 grams ≅ 1383 grams (4 sig. figs.)
