Answer:
Amplitude ----> C.) The distance from a crest or trough to the rest position on the horizontal axis
Crest ---> A.) The highest point of a wave
Destructive interference ---> E.) A situation in which the crest of one wave and the trough of another overlap, resulting in a wave that has a smaller amplitude than the original waves
Sound Wave ---> B.) A vibration transmitted through an elastic medium, such as a gas, liquid, or solid
Trough ---> D.) The lowest point of a wave

This is so basic bro u gotta first move
Answer:
I will say D. The molecules become arranged into regular cubic arrangement. but i'm not 100% sure
Explanation:
Given buffer:
potassium hydrogen tartrate/dipotassium tartrate (KHC4H4O6/K2C4H4O6 )
[KHC4H4O6] = 0.0451 M
[K2C4H4O6] = 0.028 M
Ka1 = 9.2 *10^-4
Ka2 = 4.31*10^-5
Based on Henderson-Hasselbalch equation;
pH = pKa + log [conjugate base]/[acid]
where pka = -logKa
In this case we will use the ka corresponding to the deprotonation of the second proton i.e. ka2
pH = -log Ka2 + log [K2C4H4O6]/[KHC4H4O6]
= -log (4.31*10^-5) + log [0.0451]/[0.028]
pH = 4.15
