4. You have a very concentrated solution (12 M) of potassium chloride (KCI). You need it to be at the least concentration possib
Alenkinab [10]

Answer:

C. 2.4 M

Explanation:

Because you started with 12M solution of KCl, that means that there was a concentration of 12 mols of KCl per Liter of solution. (12mol/1L =12 M). Since there was only 0.5L of solution, there was only 6 mols of KCl because there is only 12 mols per 1 Liter, so half of that volume would have half the amount of solute to keep that true. (6mol/.5L = 12 M). With the new water added, the formula becomes (6mols KCl/ 2.5L of water =2.4 M)

What features form when rocks bend?
bezimeni [28]
When the sedimentary layers of rocks are soft and under pressure they can be bent into curved structures called geosynclines. One theory is that heat partially melts the sedimentary layers of rocks allowing them to be bent into the curved shapes.

Hope this helps :)!

Is straining cooked pasta from water a physical or chemical separation
Leviafan [203]
It is a physical separation.

Only chemical separation involves the changing of substances and their bondings, which usually involves the use of heat or electricity. Meanwhile, physical changes does not require breaking the bonds of substances or changing a substance to another, common examples of physical separations are such as filtration or distillation.

Since straining pasta from water does not require breaking the pasta or water to other substances, plus heat and electricity is not involved, therefore this is a type of physical separation.
