Write balanced equations for each of the following.

Question

Write balanced equations for each of the following. Remember to use a good approach: think about what kind of chemicals are involved, what type of reaction they may be involved, what the products may be (if not given) and then write a balanced chemical equation.

a. The elements sulfur and chlorine combine to produce sulfur tetrachloride.

b. CaSO3 (s)?------>

???? c. C12H22O11 (sucrose) undergoing combustion

d. Lead azide is Pb(N3)2. It explosively decomposes to solid lead and nitrogen gas.

e. Na(s) + H2(g) ---->

Answer 1

S8 + 16 Cl2 --> 8 SCl4

 

CaSO3(s) + heat --> CaO(s) + SO2(g)

 

C12H22O11 + 12 O2 --> 12 CO2(g) + 11 H2O(g)  (assuming complete combustion)

 

Pb(N3)2 --> Pb + 3 N2

 

2 Na + H2 --> 2 NaH
