Thank you for your help!

I just had a question..
is BaO barium oxide a precipitate? or if I combine MgO with Ba(NO3), will I get BaO and is this a solid?

BaO is barium oxide. It is soluble in water forming Ba(OH)2 just as MgO is somewhat soluble in water forming Mg(OH)2.

I don't think you will see a reaction between MgO and Ba(NO3)2.

You're welcome! I'm here to help.

To determine if BaO (barium oxide) is a precipitate, we need to consider the reaction it is involved in. In this case, you mentioned combining MgO with Ba(NO3)2. Let's break down the reaction:

MgO + Ba(NO3)2 → BaO + Mg(NO3)2

From this balanced equation, we can see that BaO is indeed formed as a product. However, the state of BaO depends on the reactivity of barium and oxide ions. Barium oxide (BaO) is a white solid at room temperature and is typically encountered as a solid.

If you have any other questions or need further clarification, feel free to ask!
