At a pressure of 780.0 mm Hg and 24.2 °C, a certain gas has a volume of 350.0 mL. What will be the volume

of this gas under STP?

The new volume of the gas at stp is 367mL

Explanation:

Using general gas equation:

P1V1 / T1 = P2V2/ T2

P1 = 780mmHg

V1 = 350mL = 0.000350L

T1 = 24.2°C = 24.2 + 243= 297.2K

At stp that is standard temperature and pressure, P2 = 760mmHg

T2 = 273K

V2 = ?

To calculate V2 :

V2 = P1V1T2 / P2T1

V2 = 780 * 0.000350 * 273 / 760 * 297.2

V2 = 74.529 / 203072

V2 = 0.000367L

V2 = 367mL

question: which statement best describes the different properties of metals?

answer: they are shiny and bend without breaking.

since metals have certain characteristics properties, they include the following: they are ductile, malleable, shiny, hard, lustrous, flexible and they are good conductor of heat and electricity. so therefore, metals are not dull and they are not non-flexible as listed. instead, they are shiny and flexible.

hope this , have a good day. c;
