Answer:
2. 110.
Explanation:
- Kindly find the attached image.
From the solubility curve, you can find that at 45°C to make a saturated solution of this salt, you should add 110 g of NaNO₃.
- So, the right choice: 2. 110.
Answer:
0.5667 M ≅ 0.57 M.
Explanation:
It is known that the no. of millimoles of a solution before dilution is equal to the no. of millimoles of the solution after the dilution.
It can be expressed as:
(MV) before dilution = (MV) after dilution.
M before dilution = 1.5 M, V before dilution = 340 mL.
M after dilution = ??? M, V after dilution = 340 mL + 560 mL = 900 mL.
∴ M after dilution = (MV) before dilution/(V) after dilution = (1.5 M)(340 mL)/(900 mL) = 0.5667 M ≅ 0.57 M.
Answer:
false
Explanation:
it's false because im big brain
Answer: From the reaction, we can conclude the following about equilibrium;
The reaction will favour the reactants because ammonia is a stronger base compare to the sulphate ion.
