Draw the structure of the carbonyl compound and amine which may be used to make the teritiary amine.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

they are both synthetic elements

explanation:

d

"record the time to complete a chemical reaction" would most likely be part of a lab procedure.
