Question

TOPIC: Chemical Reactions

Select the two (2) chemical reactions that are balanced.
OC2 H4 (g) + O2 (g)
OC2 H4 (g) + 302 (g)
Mg(s) + HCL(g)
Mg(s) + 2HCL(g)
CO2 (g) + H₂ O(1)
-> 2CO2 (g) + 2H₂O (1)
-> MgCl2(aq) + H2(g)
-> MgCl2(aq) + H2(g)

Answer 1

C2H4(g) + 3O2(g) ----> 2CO2 + 2H2O(l)

Mg(s) + 2HCL(l) ----> MgCl2(aq) + H2(g)
