Asample of 500 ml ne gas is at 0.868 atm and 55 c. what is the new volume if the pressure is increased to 1.35 atm and the temperature is decreased to 25 c

292.10 mL

From the question we are given;

                                                              = 298.15 K

We are required to calculate the new volume, V2 of the gas;

Using the combined gas equation;

Rearranging the formula we can calculate the new volume, V2;

Therefore, the new volume is 292.10 mL

i'm pretty sure it is letter c.) car

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
