During an experiment 1,8g of magnesium reacts with excess dilute hydrochloric acid to produce hydrogen gas STP.
Mg + 2 HCl(aq) + MgCl2(aq) + H2 (g).
Calculate:
1. Mass Of the Ha produced
3. Volume in (dm³) of H(aq) produced
3. Mass in grams of MgCl2 produced
4. Number of Chlorine atoms present in MgCl2
