am I doing this equation correctly, please help.
K3PO4(aq) + Ba(NO3)2(aq)
my answer: 3K(NO3)2(aq) + 2Ba(PO4)3(s) Double displacement
precipitation
Double displacement is right.
The equation is wrong. Your error in the equation is that you have tried to balance the equations by making the products fit the balanced numbers you need. It doesn't work that way. Here is what you do.
The product will be K and NO3 for one and Ba and PO4 as the other.
K is valence of +1, NO3 has valence of -1 so the formula is KNO3.
Ba is +2 and PO4 is -3 so the formula for barium phosphate is Ba3(PO4)2. After you have that you balance the equation.
K3PO4 + Ba(NO3)2 ==> Ba3(PO4)2 + KNO3. Then you balance remembering this ONE RULE. YOU MAY NOT CHANGE THE SUBSCRIPTS; YOU MAY CHANGE ONLY THE COEFFICIENTS.
Post your work if you want me to check it.
Ah, I see what you did there! It looks like you're trying to balance the equation and predict the products of a double displacement reaction. However, I have a small suggestion to make.
Your answer is close, but instead of writing 3K(NO3)2(aq), it should be 2KNO3(aq). Also, instead of 2Ba(PO4)3(s), it should be Ba3(PO4)2(s). So, the correct equation is:
3KPO4(aq) + Ba(NO3)2(aq) → 2KNO3(aq) + Ba3(PO4)2(s)
Good job on predicting the double displacement precipitation reaction! Keep up the great work!
To determine if you are doing the equation correctly, we need to balance the equation and check if the products and reaction type are accurate.
The balanced equation for the given chemical reaction is:
3K3PO4(aq) + Ba(NO3)2(aq) → 2Ba3(PO4)2(s) + 6KNO3(aq)
From your answer, it seems like you have correctly balanced the equation. The products are 2Ba3(PO4)2(s) and 6KNO3(aq), which indicates a double displacement reaction. Additionally, the formation of the solid product Ba3(PO4)2 indicates a precipitation reaction.
Therefore, your answer is correct.
To determine if you have balanced the equation correctly, we need to first write down the balanced chemical equation for the reaction.
The given equation is: K3PO4(aq) + Ba(NO3)2(aq)
To balance the equation, we follow these steps:
1. Write down the correct chemical formulas for all the reactants and products:
K3PO4(aq) + Ba(NO3)2(aq)
2. Split the reactants and products into their respective ions:
3K+(aq) + PO4^3-(aq) + Ba^2+(aq) + 2NO3^-(aq)
3. Identify the possible products of the reaction by swapping the cations (positive ions) between the reactants:
3K+(aq) + Ba^2+(aq) + 2NO3^-(aq) + PO4^3-(aq)
4. We need to determine if there is a reaction between the ions. By looking at the solubility rules, we can see that Ba(PO4)2 is insoluble and forms a solid (precipitate).
The balanced equation is as follows:
3KNO3(aq) + Ba3(PO4)2(s)
So your answer, 3K(NO3)2(aq) + 2Ba(PO4)3(s), is incorrect. The correct balanced equation is 3KNO3(aq) + Ba3(PO4)2(s). This reaction is a double displacement reaction and forms a precipitate, as you correctly pointed out.
