The volume of a gas at 6.0 atm is 2.5 l. what is the volume of the gas at 7.5 atm at the same temperature?

The answer is:

The new volume is:

Since the temperature keeps constant, we need to use the Boyle's Law in order to solve the problem.

The Boyle's Law states that:

Where,

P is the pressure of the gas.

V is the volume of the gas.

From the statement we know that:

Let's substitute the values into the equation:

So, the new volume is:

Have a nice day!

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

the answer is barium and copper bromide
