I'm pretty sure it's B)constructive
Alll are correct. Matter is literally everywhere
Answer: The volume of 0.235 M 
needed to titrate 40.0 mL of 0.0500 M 
is 8.51 ml
Explanation:
To calculate the volume of acid, we use the equation given by neutralization reaction:
where,
are the n-factor, molarity and volume of acid which is
are the n-factor, molarity and volume of base which is
We are given:
Putting values in above equation, we get:
Thus volume of 0.235 M needed to titrate 40.0 mL of 0.0500 M is 8.51 ml
<span>The
balanced half-reaction: V</span>⁺(aq) → V⁵⁺(aq) + 4e⁻.
Vanadium(I) cations lose four electrons and became vanadium(V) cations.

Oxidation reaction is increasing of oxidation number of element, because
element or ion lost electrons in chemical reaction.
Reduction is lowering oxidation number because element or ions gain
electrons.</span>
