___________ would albumin expect to dissociate into individual ions and increase the number of osmols/mol in solution.

Lubov Fominskaja [6]

Answer: Check explanation please.

Explanation:

Before diving into the question,let us consider some important facts and definitions.

WHAT IS OSMOLARITY? Osmolarity is the number of OSMOLES of solute per litre of the solution. The unit of osmolary is OSMOLE. Nowadays, osmolarity has become a term used in the past, now osmolarity is called osmotic concentration.

OSMOLARITY can be calculated using; Σ(osmotic coefficient × number of ion × the solute molar concentration).

BACK TO THE QUESTION; ALBUMIN is a PROTEIN. Protein is a large molecule and it contributes an insignificant amount to osmolarity(around 0.6 Mosmole/litre).

Also, if we have the osmotic coefficient to be between zero and one, there is going to be great DISSOCIATION.

What is the empirical formula for a compound that contains 10.89% magnesium 31.77% chloride and 57.34% oxygen

Blizzard [7]

Answer: $Mg_{1}Cl_{2}O_{8}$

Explanation:

If percentage are given then we are taking total mass is 100 grams.So, the mass of each element is equal to the percentage given.

Mass of Mg = 10.89 g

Mass of Cl = 31.77 g

Mass of O = 57.34 g

Step 1 : convert given masses into moles.

Moles of Mg= $\frac {\text{ given mass of Mg}}{\text{ molar mass of Mg}}= \frac {10.89g}{24g/mole}=0.45moles$

Moles of Cl = $\frac {\text{ given mass of Cl}}{\text{ molar mass of Cl}}= \frac {31.77g}{35.5g/mole}=0.89moles$

Moles of O = $\frac {\text{ given mass of O}}{\text{ molar mass of O}}=\frac {57.34g}{16g/mole}=3.58moles$

Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.

For Mg = $\frac {0.45}{0.45}=1$

For Cl = $\frac {0.89}{0.45}=2$

For O= $\frac {3.58}{0.45}=8$

The ratio of Mg :Cl : O= 1 : 2 : 8

Hence the empirical formula is $Mg_{1}Cl_{2}O_{8}$

Which substance contains bonds that involved the transfer of electrons from one atom to another?

Ivanshal [37]

The transfer of electrons is an ionic bond, therefore, we need to determine which substance includes an ionic bond.

CO2, is a covalent bond, which is the sharing of electrons, not transfer.
KBr, is an ionic bond, because (k) loses an electron to bromine.

So, our final answer is:- <span>(3) KBr</span>
