Write balanced chemical equation for the following
a) Potassium iodide and chlorine
Answers
Answer:
(a) Potassium bromide(aq) + Barium iodide(aq) → Potassium iodide(aq) + Barium bromide(s)
2KBr
(aq)
+BaI
2
(aq)
→2KI
(aq)
+BaBr
2
(s)
In this reaction, both the reactants exchanges ions to for two new products, hence, it is a double displacement reaction
(b) zinc carbonate(s) → Zinc oxide(s) + Carbon dioxide(g)
ZnCO
3
(s)
→ZnO
(s)
+CO
2
(g)
In this reaction, a single substance yields two different product. hence, it is a decomposition reaction
(c) Hydrogen(g) + Chlorine(g) → Hydrogen chloride(g)
H
2
(g)
+Cl
2
(g)
→2HCl
(g)
In this reaction, two different reactants react with each other to form a single product. Hence, it is called a combination reaction
(d) Magnesium(s) + Hydrochloric acid(aq) → Magnesium chloride(aq) + Hydrogen(g)
Mg
(s)
+2HCl
(aq)
→MgCl
2
(aq)
+H
2
(g)
In this reaction, more reactive Mg is replacing less reactive H. Hence, it is displacement reaction
Explanation:
Answer:
2Kl + Cl 2 is equal to 2Kl + l. 2
Explanation:
Potassium iodide react with chlorine to produce potassium chloride and iodide.
