<span>B) A group of gas particles will have an average kinetic energy based on energy of the gas particles </span>
Answer:

Explanation:
No of electrons, n = 20
We need to find the total charge. We can use quantization of electric charge in this case.
Net charge,
q = ne
e is charge on an electron

So, there are
of charge in 20 electrons.
Answer:
what is the question then we can help you out
6.0m(mol/kg) of HCl
125mL H2O = 0.125kg
6mol/kg = n mol/0.125kg, n = 0.75mol
When 0.75mol of HCl reacts, 0.75/2=0.375mol of H2 is produced. H2 = 2g/mol
So, 0.375mol H2 = 0.75g
I think it’s going to be a
