<u>Answer:</u> The final temperature of the gas is -220.6°C
<u>Explanation:</u>
To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,

where,
are the initial pressure and temperature of the gas.
are the final pressure and temperature of the gas.
We are given:
![P_1=6atm\\T_1=-33^oC=[273-33]K=240K\\P_2=1.31atm\\T_2=?](https://tex.z-dn.net/?f=P_1%3D6atm%5C%5CT_1%3D-33%5EoC%3D%5B273-33%5DK%3D240K%5C%5CP_2%3D1.31atm%5C%5CT_2%3D%3F)
Putting values in above equation, we get:

Converting the temperature from kelvins to degree Celsius, by using the conversion factor:


Hence, the final temperature of the gas is -220.6°C
(4) covalent is your answer.
Answer:
F. a dark solid formed on the zinc.
-Is because when the solid is formed it is called the "precipitate", which is commonly know as chemical reaction.
Its chemical formula H2O, indicates that each of its molecules contains one oxygen and two hydrogen atoms, connected by covalent bonds. The hydrogen atoms are attached to the oxygen atom at an angle of 104.45°. "Water" is the name of the liquid state of H2O at standard conditions for temperature and pressure.
