A balloon is filled with 0.198 liters of NH3 gas at constant pressure. If the temperature of the gas is increased from -103.79 C to 380.25 K, what is the new volume of the balloon in liters (round to the nearest tenths place).

V2 = V1 · T2/ T1

Explanation: in constant pressure V/T = constant.

Convert starting temperature T1 to Kelvins T1 = (273.15 -103.79)K

V1 = 0.198 litres. V2 = 380.25 K

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: )
