2 Ca₅(PO₄)₃F + 7 H₂SO₄ → 3 Ca(H₂PO₄)₂ + 7 CaSO₄ + 2 HF
Explanation:
To balance the chemical reaction the number and type of atoms entering the reaction have to be equal to the type and atoms leaving the reaction.
In our case we have:
10 Ca entering the reaction and 10 Ca leaving the reaction
6 PO₄ groups entering the reaction and 6 PO₄ groups leaving the reaction
2 F entering the reaction and 2 F leaving the reaction
7 SO₄ groups entering the reaction and 7 SO₄ groups leaving the reaction
14 H entering the reaction and 14 H leaving the reaction

Answer: those are the best questions to answer kfnmbysjghfbs they are literally so unnecassary, but the teaaaaaaa
Explanation:
I did this question before and the answer is Magnesium and silicon, B.
If we have in mind the following procedure:
BACo3(s) + H +1 -> Ba +2 + HCO3 -1
CO3 - 2 + H+1 -> HCO3 -1
As nitric acid is added then {CO3 -2 } decreases meaning that more BaCo3 can dissolve. The graph you need to use is the one that the curve goes down and closer to solubility and goes up on conc.
