What is diabetes? How does it disrupt normal cellular activities? What are the overall consequences for your body?
Vlad1618 [11]

Answer:

Diabetes is a group of diseases that affect how your body uses blood sugar (glucose). Glucose is vital to your health because it's an important source of energy for the cells. Cells are everywhere including the blood, bones and muscles. When you have diabetes, you don’t have enough insulin in your blood (an organ in your body called the pancreas makes insulin). Insulin controls the movement of blood sugar into the cells of the body.

The Ksp for CaF2 is 3.9 x 10-11 at 25oC. What is the solubility?
nevsk [136]

We have to know the solubility of CaF₂.

The solubility of CaF₂ is: (c) 2.1 x 10-4 Molar

The general expression of solubility product of any sparingly soluble salt (having solubility S) with formula A_{x} B_{y} is: x^{x} y^{y} S^{x+y}.

For the compound, CaF₂, x=1, y=2 So, K_{sp}=1^{1}2^{2}S^{1+2}=4S³= 3.9 x 10-11  (Given)

S³=\frac{3.9 X 10^{-11} }{4}

S³=9.75  X 10^{-12}

S= 2.1 X 10^{-4} Molar
