Answer:
A tiny sense positively charge core called a nucleus in which nearly all the mass is concentratedm
I think its the mirror because condenser helps in allowing the amount of light to pass.
Answer:
Explanation is in the answer
Explanation:
The pH of the buffer solution does not change appreciably because the strong acid (free H⁺) reacts with conjugate base of buffer producing more weak acid. pH formula of buffers is (Henderson-Hasselbalch formula):
pH = pKa + log ( [A⁻] / [HA] )
The addition of strong acid decreases [A⁻] increasing [HA]. pH change just in the log of the ratio of [A⁻] with [HA], that is a real little effect over pH of the buffer solution.
Answer:
its all of them ✨
Explanation:
i idk why there its all of them tho i promise you
