No links need real answer please. What is the number of mole equivalents of H2
produced by the reaction of 1 mole equivalent of
Mg (s) with H2SO4 (aq), according to the reaction
shown below?

Mg(s) + H2SO4 (aq) → H2 (g) + MgSO4 (aq)
mole(s)

the answer is a for sure mark brainliest i had got this right on usatestprep

ca has a crystalline lattice with positive ions (since it is a metal, metals are positively charged) and electrons flow freely in its structure since the ca atoms have a large nuclear radius so the electrons are not tightly held, therefore the electrons can flow freely since they are not being highly attracted by the nucleus. moreover, one of the properties of metals are that they are conductors of electricity, thus proving ca is the element.
