Chemistry test tommorow balancing word equations

[Hellohi]

Homework Statement

O.k so, I am kinda noob to chem to. We got a test tommorow on Balancing Chemical equations and I need help (I would be grateful!). I can balance the number and letter ones example: 2al+H2SO4 --> Ak2(SO4)3 + H2

I can do those ones but I can't do these ones (no matter how easy they are:( )

Mercury + oxygen --> Mercuric oxide

Ferric oxide + hydrogen --> iron + water

Please I'd be very grateful if I got a quick detailed response.

Btw I am not in university yet so please make it just a bit simple, thank you very much:D

Homework Equations

none.

The Attempt at a Solution

I really don't know how to do these kinds, only the kinds I was talking about at the top.

Please I'd be very grateful if I got a quick detailed response.

You study and learn how to name and what are elements, compounds, and atoms. You use this knowledge to understand what is being given in word-given reactions.

Mercury plus oxygen giving mercuric oxide would be understood as mercury as a metal plus oxygen as the diatomic gas; and mercuric oxide would be the higher "oxidation" state of mercury ion.
