Answer: In simplest case mass of reactants is same as mass of products.
Without thinking this question deeper, mass of ZnCl2 would be 49, but..
Explanation: Reaction should be Zn + 2 HCl ⇒ ZnCl2 + H2
Amount of zinc is 5 g / 65,38 g/mol = 0,076476 mol and amount
of Hydrogen Chloride is 50 g / 36.458 g/mol = 1,371 mol.
Althought HCl is needed 0.152 moles, zinc is an limiting reactant.
So it is possible to produce only 0.076476 mol Hydrogen and its mass
is 0.154 g. Mass of ZnCl2 would be 0.076476 mol · (65.38 + 2·35.45) =
10.42 g

Explanation:
The open spaces in water's crystal structure make it possible for <span>aquatic life to exist at the north pole.
It is good to know that, at the north pole, when the temperature drops below zero, only the top layer of the water freezes. Underneath this freezing layer, water remains in its liquid form, thus, allowing marine life to exist. As for oxygen, it is also trapped underneath the ice layer. </span>
