E. Also the equilibrium constant should not have units.
>(7.5 * 10^23) molecules / (6.022 * 10^23 molecules / mole) = 1.2 mol H2SO4 Third multiply moles H2SO4 by molar mass of H2SO4.<
KCl + H2O
because acid + base gives salt and water

Answer:
11
Explanation:
Data obtained from the question include:
Mass number = 23
Neutron = 12
Atomic number =.?
Next, we shall determine the number of protons present in the element.
This can be achieved by doing the following:
Mass number = Proton + Neutron
Mass number = 23
Neutron = 12
Proton =...?
Mass number = Proton + Neutron
23 = Proton + 12
Collect like terms
Proton = 23 – 12
Proton = 11
The atomic number of an element is equal to the proton number.
Atomic number = proton number
Proton number = 11
Atomic number = proton = 11
Therefore, the atomic number is 11.
