Please give me balanced chemical equations for the following reactions.?

Question

1- sodium + water ----> sodium hydroxide + hydrogen
2- Magnesium + steam ----> magnesium oxide + hydrogen
3- Hydrogen + mitrogen ----> ammonia
4- Magnesium + carbon dioxide ---> magnesium oxide+carbon

Answer 1

Here's the equations with state symbols, where (s) means solid, (l) means liquid, (g) gas, (aq) aqueous
1. 2Na (s) + 2H2O (l) -----> 2NaOH (aq) + H2 (g)
2. Mg (s) + H2O (g) -------> MgO (s) + H2 (g)
3. 3H2 (g) + 2N2 (g) --------> 2NH3 (g)
4. Mg (s) + CO2 (g) ---------> MgO (s) + C (s)

Answer 2

2 Na + 2 H2O ---> 2 NaOH + H2

Mg + H2O ---> MgO + H2

3H2 + N2 ---> 2NH3

2 Mg + CO2 ---> 2 MgO + C

Answer 3

Am I doing your homework? ;-)

2Na + H2O --> 2NaOH + H2

Mg + H2O --> MgO + H2

3H2 + N2 --> 2NH3

2Mg + CO2 --> 2MgO + C

Answer 4

Please remember the factor is iron,(Fe) ,not iron(II), Fe+2. additionally the reaction between iron and fluorine produce iron(III)fluoride. The equation for this reaction is: 2Fe(s) + 3F2(g) --> 2FeF3 (s)

Answer 5

Na+H2O --> NaOH+H
Mg+H2O--> MgO +2H
3H + N --> NH3
2Mg + CO2 --> 2MgO + C
