Answer 1

\(1.Fe_3O_4+4H_2\underrightarrow{t^o>570}3Fe+4H_2O\)

2. \(Fe\left(OH\right)_3+3HCl\rightarrow FeCl_3+3H_2O\)

3. \(2CO+O_2\underrightarrow{t^o}2CO_2\uparrow\)

4. \(Na+\dfrac{1}{2}Cl_2\underrightarrow{t^o}NaCl\)

5. \(2AgNO_3\underrightarrow{t^o}2Ag+2NO_2\uparrow+O_2\uparrow\)

6. \(2Fe+3I_2\rightarrow2FeI_3\)

7. \(4Fe_xO_y+\left(3x-2y\right)O_2\rightarrow2xFe_2O_3\)

8. \(xFe_2O_3+\left(3x-2y\right)H_2\rightarrow2Fe_xO_y+\left(3x-2y\right)H_2O\)

9. \(M_xO_y+2yHCl\rightarrow xMCl_{\dfrac{2y}{x}}+yH_2O\)

Answer 2

\(1,Fe_3O_4+3H_2\rightarrow3Fe+3H_2O\)

\(2,Fe\left(OH\right)_3+3HCl\rightarrow FeCl_3+3H_2O\)

\(3,2CO+O_2\rightarrow2CO_2\)

\(4,2Na+Cl_2\rightarrow2NaCl\)

\(5,2AgNO_3\rightarrow2Ag+2NO_2+O_2\)

\(6,2Fe+3I_2\rightarrow2FeI_3\)

\(7,2Fe_xO_y+\left(x-2y\right)O_2\rightarrow xFe_2O_2\)

\(8,Fe_2O_3+\left(3-\dfrac{2y}{x}\right)H_2\rightarrow\dfrac{2}{x}Fe_xO_y+\left(3-\dfrac{2y}{x}\right)H_2O\)\(9,M_xO_y+2yHCl\rightarrow xMCl_{\dfrac{2y}{x}}+yH_2O\)

\(10,C_xH_y\left(COOH\right)_2+\dfrac{2-4x+y}{4}O_2\rightarrow\left(x+2\right)CO_2+\dfrac{y+2}{2}H_2O\)
