Question

REX Balance the following chemical equations: A
a) MgO+H20
Mg(OH)2
B) Al + H20
H2 + Al2O3
o AgNO3+ Cu
Cu (NO3)2 + Ag​

Answer 1

Answer:

1. It is completely balanced
2. 2Al+3H2O→3H2+Al2O3
3. 2AgNO3+Cu→Cu(NO3)2+2Ag

Answer 2

Answer:

a) this equation is already balanced.

MgO + H2O => Mg(OH) 2

b) 2Al + 3H2O => 3H2 + Al2O3

c) 2AgNO3 + Cu => Cu(NO3)2 + 2Ag
