Answer:

b. halogens

Explanation:

The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. Halogens are very reactive these elements cannot be found free in nature. Their chemical properties are resemble greatly with each other. As we move down the group in periodic table size of halogens increases that's way fluorine is smaller in size as compared to other halogens elements. Their boiling points also increases down the group which changes their physical states.

A common anesthetic in dentistry known as nitronox consists of a mixture of dinitrogen oxide, n2o, and oxygen gas, o2, which is

Nesterboy [21]

Anesthetic in dentistry consists of a mixture of dinitrogen oxide (N₂O) and oxygen gas (O₂), which is administered through an inhaler over the nose. Total pressure of the mixture ( $P_{total}$ ) is sum of partial pressure of N₂O ( $p_{N_{2}O }$ ) and partial pressure of O₂, ( $p_{O_{2} }$ ).

$P_{total}=p_{N_{2}O } + p_{O_{2} }$

$P_{total}= 740 mmHg, p_{O_{2} }$ =370 mmHg

So, $p_{N_{2}O }$ = (740-370) mmHg= 370 mmHg=370 torr

Hence, partial pressure of N₂O is 370 torr.

As, 1mmHg= 1 torr.

20 mL of a gas at 200K is heated until the new volume is 55 mL. What is the final temperature of the gas?

Lostsunrise [7]

Answer:

550 K

Explanation:

Given the following data;

Original Volume, V1 = 20mL

Original Temperature, T1 = 200K

New Temperature, V2 = 55mL

To find new temperature T2, we would use Charles' law.

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles is given by;

$VT = K$
