third order 

200

Atoms with the smallest atomic radii will be found where on the periodic table?

Up and to the right

200

What are the IMFs present among C8H16OH molecules?

What are the spectator ions in the reaction between KOH and HNO3

K+ and NO3-1

200

What factors are important to determine if a chemical reaction will occur? Hint: Collison theory

The speed  that the particles collide with 

The orientation that they collide with 

particles will only react if they overcome the energy curve 

300

Ionization energy increases in the periodic table...

As you go up a group and from left to right 

300

Is it possible to have a polar trigonal planar molecule?

Yes if not all the terminal atoms are the same

300

will check answers (tetrahedral). 109.5 degrees.

300

What is the concentration of chloride ions in a 0.193 M solution of potassium chloride?

0.193 M

300

How would I determine the order of a reaction that is graphed with time and concentration 

Graph three graphs 

[A] vs time 

ln[A] vs time 

1/A vs time 

Determine which is linear 

400

What does ionization energy refer to?

Energy needed rip away a valence electron from an atom

400

Why is COnonpolar but SO2 is polar?

The S has an extra lone pair which makes the shape bent. 

400

      1           .20        .10    2.5

      2           .20       .20     5

      3           .40        .20    5

rate = k [B]

500

What are the two factors in determining the strength of the attractive force between two charged particles in Coulomb's Law?

Distance and size of the charge

500

Why is water polar but carbon dioxide is not? What IMFs do they experience 

Water has a bent shape so the dipoles don't cancel each other out. Carbon is linear so the dipoles do cancel each other out. 

Water hydrogen bonding

COLDF
