Answer:
383.90K
Explanation:
P1 = 851mmHg
T1 = 330K
T2 = ?
P2 = 990mmHg
To solve for P2, we have to use pressure law which states that the pressure of a fixed mass of fixed is directly proportional to its temperature provided that volume remains constant
Mathematically,
P = kT, k = P/T
P1 / T1 = P2 / T2 = P3 / T3 =.......=Pn / Tn
P1 / T1 = P2 / T2
T2 = (P2 × T1) / P1
T2 = (990 × 330) / 851
T2 = 383.90K
The final temperature of the gas is 383.90K

Explanation:
Chlorine is a member of the halogen family known as a toxic yellowish green gas. Inhalation of chlorine for a prolonged period of time leads to pulmonary edema. If a person comes in contact with compressed liquid chlorine the person may experience frostbite of the skin and eyes.
However chlorine is very useful in water disinfection and is preferred in water treatment because it provides residual disinfection of the treated water.
Chlorine gas may be dissolved in NaOH to form oxochlorate I which is used as a bleach in cleaning.
Give me a thanks I been helped a lot of people and non of them is thanks me.
<span>Gold have a single outer electron. This seems disadvantageous, energy-wise, until you look at the orbitals the electrons are in. The lone electron is in an S-orbital. This orbital is thus half full (since s-orbitals can contain 2 electrons), whereas all the other inner orbitals in silver and gold are filled, and hence exceptionally stable. After a full orbital, the next most stable orbital is a half full one. </span>
