Help me with balancing chemical equations please?

I have two questions on my homework that i'm not sure what the answer is, the wording is a little confusing and it's due tomorrow. Can someone help me get the answers?

1. For each of the reactants and type of reaction listed, write out the correctly balanced chemical equation. Silver nitrate and sodium sulfide in a double displacement reaction.

2. For each of the reactants and type of reaction listed, write out the correctly balanced chemical equation. Aluminum metal and silver nitrate react in a single replacement reaction.

Thanks in advance for any help you can give.
