Among the following options, a valid Lewis structure of __________ cannot be drawn without violating the octet rule.

Murrr4er [49]

Answer:

d. IF3

Explanation:

The Octet rule posits that atoms gain, atom lose, or share electrons in order to have a full valence shell of 8 electrons. This statement occurs when atoms also combine to form molecules until they attain or share eight valence electrons either by losing or gaining eletrons.

From the given options, a valid Lewis structure that cannot be drawn without violating the octet rule is IF3

The volume of a gas held at constant temperature varies indirectly as the pressure of the gas. If the volume of a gas is 1200 cu

kvasek [131]

Answer:

Volume of the gas at 500 mm Hg pressure is 960 $cm^{3}$

Explanation:

Let's assume the gas behaves ideally.

According to combined gas law for an ideal gas-

$\frac{P_{1}V_{1}}{T_{1}}=\frac{P_{2}V_{2}}{T_{2}}$

Where $P_{1}$ and $P_{2}$ are initial and final pressure of the gas respectively. $V_{1}$ and $V_{2}$ are initial and final volume of the gas respectively. $T_{1}$ and $T_{2}$ are initial and final temperature of the gas in kelvin respectively.

Here $T_{1}$ = $T_{2}$ , $V_{1}$ = 1200 $cm^{3}$ , $P_{1}$ = 400 mm Hg, $P_{2}$ = 500 mm Hg

So, $V_{2}=\frac{P_{1}V_{1}T_{2}}{T_{1}P_{2}}$

Hence $V_{2}=\frac{400\times 1200}{500}[tex]cm^{3}$ =960 $cm^{3}$ [/tex]

Hence volume of the gas at 500 mm Hg pressure is 960 $cm^{3}$
