Answer:

Water decomposes into hydrogen and oxygen on passing electric current through acidulated water. Therefore, it is a decomposition reaction.

Explanation:

When an electric current is passed through acidulated water, it will produce a reaction called electrolysis. If an electric current is passed through acidified water, then bubbles of oxygen gas(O2) and hydrogen(H2) gas are produced at the two electrodes immersed in it.

When electric current is passed through acidulated water , then it split into hydrogen and oxygen molecule that is H2 and O2 

Chemical equation for above reaction :-

2H20 on electrolysis given 2H2 + O2

This spilliting of water due to electricity is called electrolysis .

In electrolysis, H2 moves towards cathode as it forms positive ions whereas O2 moves towards anode as it forms negative ions .

When the volume of a gas is changed from 11.5 cm3 to ?cm the temperature will change from 415 K to 200 K

Sonja [21]

Assuming that the gas acts like an ideal gas, we can calculate for the final volume using the ideal gas law:

PV = nRT

Where P = pressure, V = volume, n = number of moles, R = gas constant, and T = temperature

Assuming that P, n, and R are constant throughout the process, we can define another constant K:

V / T = K where K = nR / P

Equating the initial and final states:

Vi / Ti = Vf / Tf

Substituting the given values:

11.5 cm^3 / 415 K = Vf / 200 K

Vf = 5.54 cm^3

If sufficient acid is used to react completely

Juli2301 [7.4K]

Solution,

Mass of Mg - 21gm

molar mass of Mg - 24gm

moles = Given mass/ Molar mass

moles = 21/24 = 0.875

1 mole of Mg produce 1 mole of H2 gas

so 0.875 mole of Mg will produce 0.875 moles of H2 gas

One mole of H2 gas = 22.4 litre

0.875 mole of H2 gas = 0.875×22.4

0.875 mole of H2 gas = 19.60 litre

So the nearest ANSWER is Option four 19.37 litre.
