Question

Balance the following equations:
(i) Zn(s) + O2(g) → ZnO(s)
(ii) Fe(s) + Cl2(g) -> FeCl2(s)
(iii) Li(s) + O2(g) - Li2O(s)
(iv) H2(g) + O2(g) -> H2O(g)
(v) Mg(s) + CO2(g) → MgO(s) + C(s)

Plz help me I am having exams tomorrow​

Answer 1

Answer:

i. 2Zn(s) + O2(g) -> 2ZnO

ii. Fe(s) + Cl2(g)->FeCl2(s)

iii. 2Li(s)+ O2-> Li2O(s)

iv. 2H2(g)+ O2(g) -> 2H2O(g)

v. 2MG(s) + CO2(g)-> 2MgO (s)+ C(s)

Answer 2

Answer:

i. 2Zn(s) + O2(g) -> 2ZnO

ii. Fe(s) + Cl2(g)->FeCl2(s)

iii. 2Li(s)+ O2-> Li2O(s)

iv. 2H2(g)+ O2(g) -> 2H2O(g)

v. 2Mg(s) + CO2(g)-> 2MgO (s)+ C(s)
