Answer 1

Answer: hope u it help u

Explanation:

1. zn+2agno3------zn(no3)2+2ag
2. n2+3h2-------2nh3
3. 3mg(oh)2+2h3po4-------->4h2o+mg(po4)2
4. 2hno3+ni-------ni(no3)2+h2
5. it is already abalanced equation
6. bacl2+na2so4-------2nacl+baso4
7. al2(co3)3-------al2o3+3co2
8. ca+2h2o-----ca(oh)2+h2
9. 2lihco3------>li2co3+h2o+co2
10. 2n2+5o2-------->2n2o5
11. mgbr2+2koh-------->2kbr+mg(oh)2
12. mn+2cucl------->2cu+mncl2
13. 8zn+s8------->8zns
