CaCl_{2} is the substance that one would anticipate lowering water's freezing point the most.

This makes use of the freezing point depression theory. When dealing with this problem, we employ the equation shown below:

T = iKfm, which is rendered as follows in English:

Vant Hoff factor times molal freezing point depression constant * Solution molality equals the change in freezing point.

The quantity of molecules, not their composition, determines the freezing point depression because it is a colligative feature.

Now that we are certain that Kf and molality will remain constant, the Van't Hoff factor, also known as "i" is our sole remaining unknown.

The number of atoms that separate from each particular molecule is known as the Van't Hoff factor. The freezing point will be more depressed the greater the Van't Hoff factor.

NaCl will dissociate into Na+ and Cl-, therefore it has I = 2 CaCl2 will dissociate into Ca2+ and 2 Cl-, so it has I = 3. Sugar (C12H22O11) has I = 1.

Choice B is the appropriate response as a result.

You are instructed to create 900. mL of a 0.29 M phosphate buffer with a pH of 7.8. You have phosphoric acid and the sodium salt
Aleksandr [31]

Answer:

B and C

Explanation:

When we have to do a buffer solution we always have to choose the reaction that has the <u>pKa closer to the desired pH value</u>. When we find the pKa values we will obtain:

pKa_1=-Log[6.9x10^-^3]=2.16

pKa_2=-Log[6.2x10^-^8]=7.20

pKa_3=-Log[4.8x10^-^13]=12.31

The closer value is pKa2 with a value of 7.2. Therefore we have to use the second reaction. In which  H_2PO_4^-^1 is the <u>acid</u> and HPO_4^-^2 is the <u>base</u>. Therefore the answer for the first question is B and the answer for the second question is C.

Summarize the relationship between an electron's energy level and its location in an atom
FromTheMoon [43]

Answer:

The further an electron is from the nucleus. the greater its energy level.

Explanation:

When an electron is close to the nucleus, it is at as low an energy level as it can get.

We must put energy into an electron to pull it away from the attraction of a nucleus.

So, electrons that are further from the nucleus are at higher energy levels.

How to know that it has a high boiling point based on the question
otez555 [7]

Answer:

The relative strength of the four intermolecular forces is: Ionic > Hydrogen bonding > dipole dipole > Van der Waals dispersion forces. ...

Boiling points increase as the number of carbons is increased.

Branching decreases boiling point.

What is the percent composition HCN?
kupik [55]

Answer:

see calculations in explanation

Explanation:

percent = part/total x 100%

part = ∑ atomic mass of element

  • hydrogen = 1.008 amu (atomic mass units)
  • carbon = 12.011 amu
  • nitrogen = 14.007 amu

total = ∑ molecular mass of compound

       = H amu  +  C amu +  Namu

       = 1.008 amu + 12.011 amu + 14.007 amu

       = 27.026 amu

%H = (1.008amu/27.026amu)100% = 3.730%

%C = (12.011amu/27.026amu)100% = 44.442%

%N = (14.007amu/27.026amu)100% = 51.827%

Check results ∑%values = 100%

3.730% + 44.442% + 51.827% = 99.999% ≅ 100%
