Which statement(s) is/are TRUE about the pressure of a gas? SELECT ALL THAT APPLY

a Pressure increases when volume increases
and temperature decreases.

b Pressure increases when temperature
increases under constant volume.

С Pressure increases when volume is
decreased under constant temperature.

D Pressure decreases when the amount of gas
is increased under constant volume and
temperature.

B and C are correct

Explanation:

a) false, pressure increases when volume decreases and temperature increases

b) true, pressure and temperature are directly proportional

c) true, pressure and volume are inversely proportional

d) false, pressure and amount of gas are directly proportional

all of these relations can be summarized by the ideal gas equation:

pV = nRT

p: pressure

V: volume

n: amount of substance

R: gas constant

T: absolute temperature

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

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: )
