Question

Write the balanced chemical equation for the following and indentify the type of reaction in
each case
a) Calcium hydroxide +Nitric acid
→ Water + Calcium nitrate
b) Magnesium + Iodine
→ Magnesium Iodide.
c) Magnesium, + Hydrochloric acid → Magnesium chloride
+ Hydrogen
d) Zinc + Calcium chloride
→ Zinc Chloride
+ Calcium
​

Answer 1

Ca(OH)2+2HNO3=2H20+Ca(NO3)2

2Mg+I2 =2MgI

Mg+2HCl=MgCl2+H2

Zn+CaCl2=ZnCl2+Ca
