    Thank you for posting your question to the Ask Me Help Desk.

    Here are some steps to help you.

    1. Use the general equation for this type of reaction to help you in finishing the equation.

    AB + CD --> AD + CB

    2. Remember that all oxidation numbers must zero out when writing the formulas.

    3. Balance using the proper rules.

    Let me know what you come up with.

    Im pretty sure you need to know what that yeilds... is it a double replacement if so.. you get NaOH + NiCl2 --> NaCl2 NiOH... I think...

    Never mind actually you can't balance that because there is no reaction... OH molecules are insoluble... read solubility rules...

    Ummm... no.

    You need to understand the rules a little better.

    Yes most hydroxides are insoluble... but NaOH isn't. Anyone who has taken chem lab has most likely used aqueous sodium hydroxides.. . now, many other OH salts are insoluble... its true, and relevant to this question. But your post makes it sound like the reagent isn't soluble.

    Please make sure you know the answer before you post.

    2NaOH + Ni(Cl)2 -> 2NaCl + Ni(OH)2

    First of all it would be NiOH that is the product. And this is insoluble. If it's insoluble it means there is a precipitate which means there was a reaction.

Chem answer [ 2 Answers ]

I not sure if I did it right, but I got 15.9. here is the question- If 40.0 grams of H3PO4 reacts with 60.0 grams of MgCO3 according to this reaction, 2H3PO4 + 3MgCO3 —> Mg3 (PO4)2 + 3CO2 + 3H2O (already balanced) Then calculate the volume of carbon dioxide gas produced at STP.
