Question

1. Balance the following equations and write word equation for each.

1. Al + Fe2 O3 -------- Al2O3

2. AgNo3 + Cu -------- Cu(No3)2 +Ag

3. H2 +N2-------- NH3

4. NaoH + Co2----------- Na2Co3 +H2)

5. Ca +HCl ----- CaCl2 + H2

6. Na +H2O ------- NaOH = H2

7. NaOH +H2So4 ------ Na2So4 +H2O

Answer 1

2) 2AgNO3 +Cu ----------Cu(NO3)2+2Ag
3) 3H2+N2 ----------2NH3
4) 4NaOH +CO2 ----------- 2Na2CO3+2H2
5) Ca+ 2HCl----------CaCl2 +H2
6)2Na+2H2O---------2NaOH+H2
7)2NaOH+H2SO4----------Na2SO4+2H2
