Question

Сколько протонов нейтронов и электронов содержится в: 3 атомах лития Li 3 сульфат-ионах SO4^-2 3 молях тетрагидроксоцинката Na2[Zn(OH)4]

Answer 1

1.3 атомах лития Li 9 p+ 12n° 9e
3 сульфат-ионах SO4^-2 80p+,80n°,82e
3 молях тетрагидроксоцинката Na2[Zn(OH)4] 264p+,285n°,264e

Answer 2

Lithium (Li)

3 atoms of lithium (Li) contain: - 3 protons - 3 neutrons - 3 electrons Each lithium atom has 3 protons, 3 neutrons, and 3 electrons.

Sulfate ion (SO4^2-)

3 sulfate ions (SO4^2-) contain: - 24 protons (3 * 8 protons in each SO4^2- ion) - 24 neutrons - 24 electrons Each sulfate ion has 8 protons, 8 neutrons, and 8 electrons. With 3 ions there are 24 of each.

Tetrahydroxozincate (Na2[Zn(OH)4])

3 moles of tetrahydroxozincate (Na2[Zn(OH)4]) contain: - 48 protons (3 * 16 protons in each [Zn(OH)4]^2- ion) - 48 neutrons - 48 electrons Each [Zn(OH)4]^2- ion has 16 protons, 16 neutrons, and 16 electrons. With 3 moles there are 3 * 16 = 48 of each.
