- If I initially have a gas at a pressure of 379 mmHg, a volume of 467 mL, and a temperature of
31°C, and then I raise the pressure to 621 mmHg and increase the temperature to 49°C, what
is the new volume of the gas?

301.89 mL

Explanation:

- Use combined gas law formula

- Rearrange that formula to fit values then plug them in.

- Be sure to change C to K

Hope that helped! Let me know if you need further explanation.

"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."
