Answer:propanoic acid

Explanation:

Carboxylic acids contain the COOH group. This group is capable of hydrogen bonding leading to association of the molecules. Cyclobutane is a cyclic alkane and acetone is a ketone. Non of these compounds posses a polar -OH bond which is necessary for the occurrence of hydrogen bond. Hydrogen bonds only occur in carboxylic acids and alcohols. Hydrogen bond leads to molecular association and high boiling points.

Answer:

The answer is: b. propanoic acid

Explanation:

The hydrogen bond or the hydrogen bridge is characterized by being a weak force that lies between a hydrogen atom and an electronegative atom. In pure substances, such a hydrogen bridge is possible, as long as there is a link between the electronegative atom and hydrogen, for example, in propanoic acid, the hydrogen bridge is possible because there is a link between oxygen and hydrogen. .

Stolb23 [73]
The freezing point constant means that the temperature depression when adding one mole of the solute. The mole number of the solute is 10.20/180=0.0567 mol. So the answer is 1.86*0.0567=0.105 ℃.

A sample of Ammonia gas at 650mmHg and 15 degree has a mass of 56.8g.calculate the volume occupied by the gas. Take N=14, H=1,R=
avanturin [10]

Answer:

The first thing we have to do is change and state all the units so that we can use our ideal gas law equation (PV = nRT).

650 mmHg is a pressure unit, we have to convert this to kiloPascals. We know that 760 mmHg gives us 101 kPa.

650 \ mmHg \ * \ \frac{101kPa}{760 mmHg} = 86 \ kPa

P = 86kPa

T = 15°C + 273K = 288K

R (Gas constant) = 8.31 kj/mol  

Molar mass of Ammonia (NH_{3}) = (1 x 3) + (14) = 17g/mol

n (moles) = \frac{mass}{molar \ mass} = \frac{56.8}{17} = 3.34 mol

V = ?

Rearrange the equation to solve for Volume:

V = \frac{nRT}{P}

Substitute the values inside:

V = \frac{(3.34)(8.31)(288)}{(86)} = 93 L (rounded)

<u>Therefore 93 L of volume is occupied by the ammonia gas.</u>
