Answer:
AgNO₃(aq) + NaCl(aq) ⇄ AgCl(s)↓ + NaNO₃(aq) Kps
2K₃PO₄(aq) + 3MgCl₂(aq) ⇄ 6KCl (aq) + Mg₃(PO₄)₂ (s)↓ Kps
Explanation:
In the first reaction (1) we have:
Silver nitrate and sodium chloride as the reactants. Then the products will be, silver chloride (s) and sodium nitrate.
We know that all the salts from the nitrate are soluble, so the chloride will react to the silver cation to make the precipitate, an insoluble salt.
AgNO₃(aq) + NaCl(aq) ⇄ AgCl(s)↓ + NaNO₃(aq) Kps
For the second reaction (2), the reactants are:
Potassium phosphate and magnessium chloride
Phosphate salts are insoluble, except for the group 1. The same as chloride that makes soluble salts with the elements from the group 1.
The equation that makes the precipitate is.
2K₃PO₄(aq) + 3MgCl₂(aq) ⇄ 6KCl (aq) + Mg₃(PO₄)₂ (s)↓ Kps
Answer: combining
Explanation: I did the quiz
This is the answer for my quiz so don't say it's wrong because it worked for mine.
Best Answer:<span> </span><span>Sorry its kind of hard to explain, you just need to study hesslaw, practice makes perfect, keep studying!
A. REACTION 2 IS MULTIPLIED BY 3 (HESS LAW)
ΔH2= -6129 j
B. IF REACTION IS REVERSED YOU FLIP THE SIGN OF ΔH
ΔH = 92.3 kJ
C. KIND OF HARD TO EXPLAIN, BUT I CAN TRY AND SHOW YOU
EQUATION 1 (FLIP) CH4 --> C + H2
EQUATION 4 (FLIP AND MULTIPLY BY 2) H2O(g) --> H2O(l)
ΔH = -890.7</span>
