Explain why you get a basic solution when you dissolve NaF in water.

SashulF [63]

Answer:

That's because in water NaF will dissolve to produce Na+,the conjugate base of a strong acid which will not react with water.however F- will behave like a bronsted base, and accept a proton from water.this is called hydrolysis reaction, because a molecule of water is broken up.

a conjugate base is what I leftover after an acid loses a hydrogen ion.

I hope this helps

Milk of magnesia has the chemical formula Mg(OH)2. What is the mass of 3.2 moles of milk of magnesia? The molar Mass of magnesiu

GenaCL600 [577]

To calculate the mass of milk of magnesia given, we need certain data like molar mass of the compound which needs the atomic mass of the atoms in the compound. We calculate as follows:

Molar mass of Mg(OH)2 = 24.3 g/mol + (2 x (16 + 1.0)) = 58.30 g/mol

Mass = 3.2 mol (58.30 g/mol) = 186.56 grams

When a person in the hospital is given fluids intravenously, the fluid is typically a saline (salt) solution with about the same

Sati [7]

Answer:

Swelling of the red blood cells occurs.

Explanation:

Distilled water makes the blood hypotonic ,. that is a less concentrated solution, to the body tissues including the red blood cells.
Therefore the water will enter the red blood cells and may cause them to lyse or swell.
Additionally , water will enter the tissue spaces and cause sweling.
But in the case of a hypertonic solution , ( a salt or saline solution ) , This swelling does not happen because the concentration of the saline will be equal or more than the blood. 
Thus the water will flow only from the blood to the solution. This will not cause swelling.
But too much of salt is also not recommended.
