+1







B.
-1







C.
+2







D.
-2

Answers

Answer 1
Answer: the electrical charge is +2 (positive)
Answer 2
Answer:

Answer:

+2

Explanation:

Calcium also has a positive charge of 2. In the case of calcium ion, we have a calcium element with a positive charge of 2.

Which salt would be the most soluble in ice water?

Answers

Answer:

the answer to the question is calcium

Final answer:

Calcium chloride is the most soluble salt in ice water due to its ability to lower the freezing point of water more than other salts.

Explanation:

When it comes to solubility in ice water, the most soluble salt would be the one that can lower the freezing point of water the most. Sodium chloride (NaCl) and its analogs calcium chloride (CaCl₂) and magnesium chloride (MgCl₂) are often used to melt ice on roads and sidewalks because they have lower freezing points than pure water. Among these salts, calcium chloride would be the most soluble in ice water. The group 2 metal salts, such as calcium chloride, dissociate to yield three particles per formula unit and provide a larger depression of the freezing point compared to sodium chloride, which dissociates to yield only two particles per formula unit.

Answers

Answer:

In contrast, wind turbines produce no greenhouse gases when generating electricity. We should note that both noise and visual pollution are environmental disadvantages of wind turbines. However, these factors don't have a negative impact on the earth, water table or the quality of the air we breathe.
