What is the pressure of a gas in torr if its pressure is 305 kPa?
FromTheMoon [43]

Answer:

the pressure of the gas in torr is 2280 torr

Explanation:

The pressure of a gas in torr can be calculated by converting its pressure in kPa to atmospheres and then converting the atmospheric pressure to torr.

One atmosphere is equal to 101.325 kPa. Therefore, the pressure of the gas in atmospheres is 305 kPa / 101.325 kPa/atm = 3.00 atm.

One torr is equal to 1/760 of an atmosphere. Therefore, the pressure of the gas in torr is 3.00 atm * 760 torr/atm = 2280 torr.

Therefore, the pressure of the gas in torr is 2280 torr

Anettt [7]

Answer:

V_2 = \frac{5V}{8}

Explanation:

I am assuming you are saying what is the final volume of the gas

Known :

Initial volume (V1) = V

Initial temperature (T1) = T

Final temperature (T2) = 5/4 T

Initial pressure (P1) = P

Final pressure (P2) = 2P

<u>Wanted: Final volume (V2)</u>

<u />

<u />\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}\\\frac{PV}{T} = \frac{(2P)V_2}{(5/4)T}\\\frac{V}{1} = \frac{(2)V_2}{5/4}\\5/4V = 2V_2\\\\V_2 = \frac{5V}{8}

qaws [65]

Answer:

2-Methyl-5-nitrothiophene  

Explanation:

The 2- and 5-positions of thiophene are the most susceptible to electrophilic aromatic substitution.

Thus, the major product from the reaction of 2-methylthiophene with HNO₃ in acetic acid is 2-methyl-5-nitrothiophene.
