PLEASE HELP FOR EXAM I'll give 5 star and brainliest

calculate the new volume if you have 2.00 L of a gas at 0 degrees Celsius, and raise the temp to 23 degrees Celsius.

using V1/T1 =V2/T2

Advice: You must convert the T numbers into degrees K - do not use degrees C. So, 23 C is 296 K.

Why are the trends and exceptions to the trends in ionization energy observed?

The two naturally occurring isotopes of chlorine are 35cl (34.969 amu, 75.77%) and 37cl (36.966 amu, 24.23%). the two naturally occurring isotopes of bromine are 79br (78.918 rm amu, 50.69%) and 81br (80.916 amu, 49.31%). chlorine and bromine combine to form bromine monochloride, brcl. 1. how many peaks will be present in a mass spectrum for brcl? the four combinations of molecule possible given these four isotopes are: 81br37cl, 81br35cl, 79br37cl, and 79br35cl. 2. what are the masses of the four different brcl molecules? express the masses using six significant figures, in decreasing numeric order (highest to lowest), separated by commas.

Why do electrons further from the nucleus have more energy
