Question

chemistry gr 7 BALANCE THE FOLLOWING EQUATIONS: 1)FeCl3 + H2O⇒ Fe(OH)3 + HCl 2)PbS + PbSO4 ⇒Pb + SO2 3)HNO3 + Ca(OH)2⇒ Ca(NO3) 2 + H2O NEED URGENT HELP.WILL MARK AS BRAINLIEST.

Answer 1

1)FeCl3 + H2O⇒ Fe(OH)3 + HCl

= FeCl3 + 3H2O⇒ Fe(OH)3 + 3HCl

2)PbS + PbSO4 ⇒Pb + SO2

= PbS + 2PbSO4 ⇒3Pb + 2SO2

3)HNO3 + Ca(OH)2⇒ Ca(NO3) 2 + H2O

= 4HNO3 + 2Ca(OH)2⇒ 2Ca(NO3) 2 + 3H2O
