NEED HELP ASAPP!!
(If you could show any work that was needed to to this problem that would be greatly appreciated)
1. Interpret the following balanced chemical equations in terms of particles, moles, and
mass. Show that the law of conservation of mass is observed.
a. N2(g) + 3H2(g) → 2NH3(g)
b. HCl(aq) + KOH(aq) → KCl(aq) + H200
c. 2Mg(s) + O2(g) → MgO(s)
2. Challenge for each of the following, balance the chemical equation; interpret the
equation in terms of particles, moles, and mass, and show that the law of conservation
of mass is observed.
a.
Na(s) + H2000 - NaOH(aq) + H2(g)
b. Zn(s) + HNO,(aq) - Zn(NO)2(aq) + N2O(g) + H2001
