Atomic mass number is the number of protons and neutrons. Subtract 80-35=45 is the number of protons. Because the atom is neutrally charged, the number of protons must equal the number of electrons, so there are 45 electrons.

Answer:

45 electrons.

Explanation:

mass number = 80

no. of neutrons = 35

Given that it is a neutrally charged atom,

no. of electrons = mass no. - no. of neutrons

                          =    80 - 35

                          =      45 electrons.

If 40.0 g of HCl react with an excess of magnesium metal, what is the theoretical yield of hydrogen?
lyudmila [28]

The balanced reaction is:<span>

Mg (s) + 2HCl (aq) --> MgCl 2 (aq) + H 2 (g) 

We are given the amount hydrochloric acid to be used for the reaction. This will be the starting point of the calculation.

40.0 g HCl ( 1 mol HCl / 36.46 g HCl) (1 mol H2 / 2 mol HCl) (2.02 g H2 / 1 mol H2) = 1.11 g H2</span>
