Write Balanced Chemical Equations for the Following (including ALL physical states)

Question

7. Cobalt(III) bromide (aq) reacts with chlorine gas forming liquid bromine and cobalt(III) chloride (aq).

8. Silver metal reacts with sulfur powder (S8 ) to form solid silver sulfide. [S8 is a naturally occurring form of sulfur]

9. When ammonia gas and oxygen gas react, they form gaseous nitrogen monoxide and liquid water

Answer 1

7. Cobalt(III) bromide (aq) reacts with chlorine gas forming liquid bromine and cobalt(III) chloride (aq).

2Co(Br)3(aq) + 3Cl2(g) ==> 3Br2(l) + 2CoCl3(aq)

8. Silver metal reacts with sulfur powder (S8 ) to form solid silver sulfide. [S8 is a naturally occurring form of sulfur]

2Ag(s) + S(s) ==> Ag₂S

9. When ammonia gas and oxygen gas react, they form gaseous nitrogen monoxide and liquid water

4NH3(g) + 5O2(g) ==> 4NO(g) + 6H2O(l)
