Here is the Answer I Hope this Helps:-

The closer the electrons are to the nucleus, the more tightly they are bound, thus increasing the electronegativity of the atom.

A sample of gas in a closed container at a temperature of 76°c and a pressure of 5.0 atm is heated to 399°c. What pressure does

NikAS [45]

Answer: The pressure that the gas exert at high temperature is 9.63 atm

Explanation:

To calculate the final pressure 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,

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

where,

$P_1\text{ and }T_1$ are the initial pressure and temperature of the gas.

$P_2\text{ and }T_2$ are the final pressure and temperature of the gas.

We are given:

$P_1=5.0atm\\T_1=76^oC=[76+273]K=349K\\P_2=?\\T_2=399^oC=[273+399]K=672K$

Putting values in above equation, we get:

$\frac{5.0atm}{349K}=\frac{P_2}{672K}\\\\P_2=9.63atm$

Hence, the pressure that the gas exert at high temperature is 9.63 atm

An atom of which of these elements most likely forms an anion? A. AI B. Br C. Ca D. Mg

Papessa [141]

The answer is B. A good way determine this is how far right the element is on the periodic table. The further right the element is, the more electronegative it is meaning it is more willing to accept an electron. This can be explained using the valence electrons and how many need to be added or removed to complete the octet. The further right you are, the easier it is for the element to just gain a few electrons instead of loose a bunch. Noble gases are the exception to this since they don't normally react though.
