Question

Balance the following chemical equations:

1. 4 Fe +302 + moisture in air ------------→

2. MgO + H2O -----------→

3 Fe + 2HCI -----------→

4 Al + H2SO -----------→

5. CO2 + H2O -----------→​

Answer 1

$\huge\sf\colorbox{yellow}{Answer}$

1. 4Fe + 3O2 + 3H2O = 2FeO2.3H2O

2. MgO + H2O = Mg(OH)2

3. Fe+ 2HCL = FeCL2 + H2

4. Al + H2SO4 = Al(SO4) + H2

5. CO2 + H2O = CO2 +H2

Answer 2

Answer:

1. 4Fe + 3O2 + 3H2O = 2FeO2.3H2O

2. MgO + H2O = Mg(OH)2

3. Fe+ 2HCL = FeCL2 + H2

4. Al + H2SO4 = Al(SO4) + H2

5. CO2 + H2O = CO2 +H2
