Answer:

The compound which are boh soluble in water and hexane is

B. Ethanol and 1-propanol

Explanation:

The compounds ethanol and 1-propanol are soluble in both hexane and water.

It is soluble in water as both consists of polar end due to hydrogen bonding present in the -OH functional group.

and both are soluble in hexane as they contain a non polar end and the alliphatic hydrocarbon chain in them.

The solubility of alcohols varies in increasing order as the hydrocarbon chain increases. And becaue of this it becomes more non polar.

Non polar properties decreases for branched molecules.

so, the correct option is ethanol and 1-propanol.

A coke has a ph of 3.5. this means that it has an excess of _______ ions and would be called a(n) _____.

Anuta_ua [19.1K]

PH (potential of hydrogen) is a numeric scale that is used to show the acidity or basicity of an aqueous solution. It tells how acidic or alkaline a substance is . The pH values ranges from 0 to 14, such that acidic solutions have values between 1 to 6.9 with most acidic having a pH value of 1 and those that are basic have values from 7.1 to 14, with most acidic having a value of 14. Acidic compounds contain replaceable hydrogen ions while basic compounds contain hrdroxyl ions. In this case, a coke has a pH of 3.5 (acidic) which means that it has an excess of hydrogen ions (H+) and would be called an acid.

Gennadij [26K]

<u>Answer:</u> The volume of the gas when the pressure and temperature has changed is 0.811 L

<u>Explanation:</u>

To calculate the volume when temperature and pressure has changed, we use the equation given by combined gas law.

The equation follows:

$\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}$

where,

$P_1,V_1\text{ and }T_1$ are the initial pressure, volume and temperature of the gas

$P_2,V_2\text{ and }T_2$ are the final pressure, volume and temperature of the gas

We are given:

Conversion factor used:

1 L = 1000 mL

1 atm = 760 mmHg

$P_1=1.00atm=760mmHg\\V_1=790mL=0.790L\\T_1=37^oC=[37+273]K=310K\\P_2=695mmHg\\V_2=?L\\T_2=18^oC=[18+273]K=291K$

Putting values in above equation, we get:

$\frac{760mmHg\times 0.790L}{310K}=\frac{695mmHg\times V_2}{291K}\\\\V_2=\frac{760\times 0.790\times 291}{310\times 695}=0.811L$

Hence, the volume of the gas when the pressure and temperature has changed is 0.811 L

Ionic compounds generally have lower boiling and melting points than covalent compounds.

Anuta_ua [19.1K]

Answer:

The given statement is false.

Explanation:

Ionic bond is formed by strong electrostatic attraction between two atoms having large difference in their electronegativity.This strong electrostatic attraction provide structural stability to the ionic compounds.For example NaCl.

The ionic compounds generally are solid in nature.As a result their melting point and boiling point are higher that covalent compounds as covalent compounds exist in liquid of gaseous state.
