balance the equation and tell what kind of reaction it is.\n3. zns (s) + o₂ (g) → zno (s) + so₂\n4. cac₂ (s) + h₂o (l) → c₂h₂ + ca(oh)₂ (aq)
Answer
Explanation:
Step1: Balance equation 3
We start by balancing the sulfur and oxygen atoms. $2ZnS(s)+3O_2(g)\rightarrow 2ZnO(s) + 2SO_2(g)$
Step2: Identify reaction type for equation 3
This is a redox reaction as sulfur in $ZnS$ is oxidized and oxygen in $O_2$ is reduced.
Step3: Balance equation 4
We balance the calcium, carbon, hydrogen and oxygen atoms. $CaC_2(s)+2H_2O(l)\rightarrow C_2H_2(g)+Ca(OH)_2(aq)$
Step4: Identify reaction type for equation 4
This is a hydrolysis reaction as $CaC_2$ reacts with water.
Answer:
- Balanced equation: $2ZnS(s)+3O_2(g)\rightarrow 2ZnO(s) + 2SO_2(g)$, Reaction type: Redox reaction
- Balanced equation: $CaC_2(s)+2H_2O(l)\rightarrow C_2H_2(g)+Ca(OH)_2(aq)$, Reaction type: Hydrolysis reaction
