A is the correct answer
groups are the vertical columns on the table. if you look at it, you can see that the atomic number and atomic mass increases as you go down.
Here is your answer the question for the combined gas laws
1s^2 2s^2 2p^<span>2 is the electronic configuration for carbon I think</span>
Surface area<span> of a solid object is a measure of the total </span>area<span> that is occupied by the surface of object.
If two objects has same mass, then smaller size particles will have greater surface area.
Thus, in order to increase the surface area of ice, one can crush it into small particles. Due to crushing, particles will break into smaller size and eventually this will result in larger surface area. </span>
Answer: heyyyooo
The bond polarity for each bond in a BH3 molecule is polar, due to the difference in electronegativities of the B and H atom. The molecular shape is trigonal planar, and the molecule is non-polar - because due to the symmetry of the molecule, the polarities cancel out.

hope this helps!
