Answer:
Explanation:
Bases are defined as having a pH over 7. That means that There are more OH- ions than H+ ions.
The answer is D.
We can classify the ion molecules as follows:
PO4^3- = Bronsted Base
ClO2- = Bronsted Base
NH4+ = Bronsted Acid
HCO3- = Both
H2PO4- = Both
For a Bronsted-Lowry acid and bases, an acid is a proton (hydrogen ion) donor. A base is a proton (hydrogen ion) acceptor. Hope this answers the question. Have a nice day.
The missing word, is approach.

Answer:
Hi, the question is incomplete. However, the question is about the calculation of volume of a product when the volume of one of the reactants is provided.
9.587 cm^3
Explanation:
The balanced equation for the chemical reaction is shown below:
⇒
In the chemical reaction above, 2 moles of water produced 4 moles of hydrogen fluoride. If 4.8 cm^3 of water were consumed, we can calculated the volume of hydrogen fluoride that would be produced as follow:
Using STP, 1 mole of gas has a volume of 22.4 L
Thus, 4.8 cm^3 = 0.0048 L is equivalent to 2.14*10^-4
since 2 moles of water produced 4 moles of hydrogen fluoride, therefore, 2.14*10^-4 would produced 2*2.14*10^-4 = 4.28*10^-4 moles
we can convert the moles to L by multiplying with 22.4
volume of hydrogen fluoride = 4.28*10^-4 * 22.4 = 0.009587 L = 9.587 cm^3
