Determine whether each of the following salts will form a solution that is acidic, basic, or pH-neutral. Possibly useful information: Kb(C5H5N)=1.7∗10−9, Kb(C6H5NH2)=3.8∗10−10, Kb(CH3NH2)=4.4∗10−4, Kb(NH3)=1.8x10−5 Ka(HF)=7.2∗10−4, Ka(HCN)=6.2∗10−10, Ka(HClO2)=1.1∗10−2, Ka(HC2H3O2)=1.8x10−5 CH3NH3CN : C5H5NHF : C6H5NH3ClO2 : NH4C2H3O2 :

How do i complete this electrolysis of water lab? i’m at home, so i don’t have the materials, and the lab didn’t properly work and was incomplete at school.

There is one girl i like and i don't know how to tell her that, i have a feeling she knows but if she doesn't i don't want to make a fool out of myself how is one way to boost my confidence on asking her out

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.
