Answer: Answer:
21.03L
Explanation:
V1 = 456mL = 0.456L
T1 = 23°C = (23 + 273.15)K = 296.15K
P1 = 50atm
V2 = ?
T2 = 273.15K
P2 = 1.0atm
Note : P2 and T2 are at STP which are 1.0atm and 273.15K
To find V2, we have to use the combined gas equation,
(P1 × V1) / T1 = (P2 × V2) / T2
P1 × V1 × T2 = P2 × V2 × T1
V2 = (P1 × V1 × T2) / (P2 × T1)
V2 = (50 × 0.456 × 273.15) / (1.0 × 296.15)
V2 = 6227.82 / 296.15
V2 = 21.029L
Final volume of the gas is 21.03L

Explanation:
The electrolysis of nickel(II) iodide yields nickel solid and iodine gas.
In the oxidation half equation;
2I^-(aq)-------> I2(g) + 2e
In the reduction half equation;
Ni^2+(aq) + 2e -----> Ni(s)
These are the half equations of the process;
The overall equation is;
Ni^2+(aq) + 2I^-(aq)-------> NiI2
Three ways water reaches from earth to atmosphere are
1. direct evaporation from the water bodies like sea,river,oceans
2. moisture from the land(you must have seen land dries out)
3.moisture from the plant(small capillaries from the plants sucks water from land n goes to atmosphere in form of vapour from leaves)
