Question

Write word equation and balanced chemical equation for the following reactions.
1. Formation of hydrogen chloride from hydrogen and chlorine gas.
2. Lead nitrate solution reacts with potassium iodide solution to give lead iodide and pottasium nitrate.
​

Answer 1

Answer:

1. word equation: hydrogen(g) + chlorine(g) -> hydrogen                                                                                               chloride(g)

    balanced chemical equation:  H₂+Cl₂ -> 2HCl

2. word equation: lead nitrate(aq)+ potassium iodide(aq) ->

                              lead iodide(s) + potassium nitrate(aq)

  balanced chemical equation: Pb(NO₃)₂ + 2KI -> PbI₂ +2 KNO₃

Answer 2

Answer:

1. H2 + CL2  =2HCL

Explanation:

H  =2                H =1 *2 =2

CL   =2             CL=1 *2 =2

2 .PB(NO3 )2+ 2KI =   2KNO3 +PBI2
