Homework Help: Chemistry

Posted by Lisa on Saturday, December 9, 2006 at 8:44pm.

Hi,
I was given the reactants for the chemical reaction and I am supposed to write the product. The equation must be balanced. Can someboy please check my work? Thanks :-)

3NaOH + Fe(NO3)3 --> Fe(OH)3 + 3Na(NO3)

2NH3 --> N2 + 3H2

2H2 + o2 --> 2H2O

4Mg + H2SO4 --> 4MgO + H2S

On the last, active metals and acids yield hydrogen gas and the metallic salt(Magnesium sulfate in this example).
Others are ok.

So the last one would be then

Mg + H2SO4 --> MgSO4 + H2

This is single-replacement reaction, right?

thank you :-)

right, single replacement.
