Question

I. Balance the equations given below:

 

1)  N2      +    H2   ->    NH3

2)  KClO3   ->    KCl +   O2

3)  NaCl   +    F2  ->   NaF +    Cl2

4)  P    +   O2 ->    P2O5

5) CH4     +   O2 ->   CO2 +   H2O

II. Write the word equations below as chemical equations and balance:

 

1) Zinc and lead (II) nitrate react to form zinc nitrate and lead

.

2) Aluminum bromide and chlorine gas react to form aluminum chloride and bromine gas.

 

3) Sodium phosphate and calcium chloride react to form calcium phosphate and sodium chloride.

 

4) Potassium metal and chlorine gas combine to form potassium chloride.

 

5) Aluminum and hydrochloric acid react to form aluminum chloride and hydrogen gas.​

Answer 1

Answer:

n2+3h2___2nh3

2KCLO3 = 2KCL+ 3O2

2NACL +F2 = 2NAF + CL2

P4 + 5O2 = 2P2O5

CH4 + 2O2 = CO2+ 2H2O

Answer 2

Answer:

1. N2+3H2 = 2NH3

2.2KCLO3 = 2KCL + 3O2

3.2NaCL + F2  =2NaF + CL2

4.2P + 3O2 = P2O5

5.LAST OE IS REDUCTION  AND OXIDATION REATION IT CANNOT BE BALANCED

2.1 .2 Zn + Pb(NO3)2 → 2 ZnNO3 + Pb

2.2 2 Al + 6 HCI → 3 H2 + 2 AICI
