Using the following electronegativity values, place the following bonds in order of polarity (1 = highest and 4 = lowest).
O = 3.5
K = 0.8
H = 2.1
Cl = 3.0
As = 2.0
N = 3.0

This classification of drug typically changes the brain's chemistry and reduces its ability to create its own endorphins.

Kp is the equilibrium constant for dissociation of the propionic acid dimer. what is the sign of the slope for a plot of the natural logarithm of kp vs. inverse temperature for this reaction?

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
