<span>Boyle's Law or Boyle-Mariotte's Law: Under constant temperature, the volume occupied by a given fixed mass of a gas is inversely proportional to its pressure.

Formula:
</span>\frac{ P_{1} }{ P_{2} } = \frac{ V_{2} }{ V_{1} }
Product of extremes equals product of means
P_{1} * V_{1} = P_{2} * V_{2}

Data:
P_{1} = 235\:kPa
V_{1} = 9.65\:L
P_{2} = 98\:kPa
V_{2} = ?

Solving:
P_{1} * V_{1} = P_{2} * V_{2}
235*9.65 = 98*V_{2}
2267.75 = 98V_{2}
98V_{2} = 2267.75
V_{2} =  \frac{2267.75}{235}
\boxed{\boxed{V_{2} \approx 23.14\:L}}\end{array}}\qquad\quad\checkmark

Answer:

Option C

CH₃CH₂CH₂COOH

Explanation:

Carbonxylic acids are compounds which has the general formula

R–COOH where R is an alkyl group.

Considering the options given in the question above,

For A:

CH₃CH₂OCH₂CH₃ is an ether compound with general formula ROR' where R and R' are both alkyl group.

For B:

CH₃CH₂CH₂CH₂OH is an alcohol with general formula ROH where R is an alkyl group.

For C:

CH₃CH₂CH₂COOH is a carbonxylic acid with general formula R–COOH where R is an alkyl group.

For D:

CH₃CH₂C=OCH₂CH₃ is a ketone compound with general formula RC=OR' where R and R' are both alkyl group

For E:

ClCH₂CH₂CH₂CH₂CH₂CH₂Br is simply an Alkyl halide with general formula XRX where X is an halogen (i.e F, Cl, Br or I) and R is an alkyl group.

From the above illustration, only option C contains a Carbonxylic compound.

Which of the following covalent bonds is the most polar?
Bezzdna [24]

Answer:

D.) H-O

Explanation:

Polarity is determined based on the difference in electronegativity of the atoms. The greater the difference, the more polar the bond. The general trend is that the atoms in the top-right corner of the periodic table are the most electronegative.

A.) is incorrect because H-H has no electronegativity difference, making it nonpolar.

B.) and C.) are incorrect because their electronegativity differences are not the greatest.

D.) is correct because the electronegativity difference between the H and O is the greatest.
