Question

8) Give chemical equation for
i) Burning of magnesium
ii) When lead nitrate react with
pottasium iodide
iii) Quick lime is dissolve in water.
iv) Metal react with dit. acid.
v) Metal carbonate read with
dil. acid.​

Answer 1

Chemical equations for

i ) Burning of magnesium ,

• 2 Mg + O2 → 2 Mg O

ii ) Lead nitrate react with potassium iodide ,

• Pb( NO3 )2 + 2 KI → 2 KNO3 + PbI2

iii ) Quick lime dissolved in water ,

• CaO + H2O → Ca ( OH ) 2

iv ) Metal react with dilute acid ,

• Metal + Dilute acid → Salt + Hydrogen gas

v ) Metal Carbonate react with Dilute acid ,

• Metal Carbonate + Dilute acid ( Say HCL ) → Metal Chloride ( salt ) + H2O + CO2 (g)
