Answer: The pressure of the gas in atmospheres is 1.76
Explanation:
According to ideal gas equation:
P = pressure of gas = ?
V = Volume of gas = 70.0 L
n = number of moles =
R = gas constant =
T =temperature =
Thus the pressure of the gas in atmospheres is 1.76
The question is incomplete, the question is;

D) drawing (4) C) drawing (3)
Answer:
B) drawing (2)
Explanation:
In Chemistry, the direction of dipole is shown from positive end to negative end.
The image that contains the options in the question asked has been attached.
We can see in image 2 that the oxygen atom was correctly designated as the negative end of the dipole while the carbon and hydrogen atoms were each designated as positive ends of the dipole in accordance with the magnitude of electronegativity difference between the two atoms. The net dipole moment is now taken in the direction shown in image 2. This is the correct answer.
