0.050 moles of hydrogen gas are liberated when a given quantity of charge liberates 0.050 moles of lead.
<h3>What amount in moles of hydrogen will be produced?</h3>
The amount in moles of hydrogen produced when the same quantity of electricity is passed through different electrolytes is inversely proportional to the charge on the ions.
The charge on the Lead ion is +2.
The charge on the hydrogen ion is +1.
2 atoms of hydrogen gives one molecule of hydrogen gas.
Hence, equal charge liberates equal amounts in moles of lead and hydrogen gas.
Therefore, 0.050 moles of hydrogen gas are liberated when a given quantity of charge liberates 0.050 moles of lead.

Answer:
Nuclear fission power plants have the disadvantage of generating unstable nuclei; some of these are radioactive for millions of years. Fusion on the other hand does not create any long-lived radioactive nuclear waste. A fusion reactor produces helium, which is an inert gas.
<span>Mass of CH2 = 12 + 2 = 14 g/mol
The number of CH2s there are.
So since the total mass is 84.2 g/mol.
The solution is
84.2/14 = 6.012 thus the answer is 6
There are 6(CH2)
So the molecular formula is C6H12</span>
<h3><u>Answer;</u></h3>
= 3.12 moles of NaNO3
<h3><u>Explanation</u>;</h3>
The equation for the reaction is;
Pb(NO3)2+Na2CrO4 → PbCrO4+2NaNO3
Molar ratios in the reaction are ; 1 : 1 : 1 : 2
Which means; One mole of (Na2CrO4) produces two moles of (NaNO3)
We can calculate the number of moles of Na2CrO4,
Moles (na2CrO4) = 253g /162
= 1.56 moles
Moles of NaNO3 will be;
= 1.56 moles x 2 = 3.12 moles
Therefore, the moles of NaNO3 that will be produced will be 3.12 moles
