A

Ionic

24
Q

In general, atomic radius increases moving (up / down) a group due to the increasing number of electron shells

A

Down

25
Q

In general, atomic radius (increases/ decreases) moving from left to right across a period due to increasing number of protons in the energy level.

A

Decreases

26

A

Synthesis

39
Q

CH³COOH + H²O —> CH³OO- + H³O+
which is the brønsted Lowry Acid / Base

A

CH³COOH is Bronsted Lowry Acid because it released (H) CH³COO

H²O Accepted an H so it is a Bronsted Lowry Base H³O+

40
