Answer:
pOH=11.3
Explanation:
pH= -log[H+]=-log[0.002]=2.7
pOH+pH = 14
pOH= 14-2.7=11.3
Answer:
1 mole
Explanation:
The mole (mol) is the amount of a substance that contains the same number of entities as there are atoms in exactly 12 g of carbon-12. One mole (1 mol) contains 6.022x1023 entities (to four significant figures).
A: It prevents most reactions from occurring spontaneously.
The answer above is correct.

Explanation:
Answer:
Here's how I would do it.
Explanation:
A Lewis structure shows the valence electrons surrounding the atoms.
1. Identify the central atoms
The central atoms are the least electronegative atoms (C).
I chose as my central atoms a chain of four C atoms: C-C-C-C
I stuck the most electronegative atom (O) at the end of the chain:
C-C-C-C-O
2. Complete the structure
The hydrogen atoms must be terminal. Add enough to give every atom an octet.
You should get a structure like the one below
