Both strong acid and strong base will alter the solubility and the nature of a protein. This is because, adding a strong acid or base to a protein will drastically change the pH of the protein and this will leads to formation of precipitation and denaturation of the protein.
Answer:
B. The amounts of water and alcohol are not the same
Explanation:
Answer:
<h2>2.709 × 10²⁴ molecules</h2>
Explanation:
The number of molecules can be found by using the formula
N = n × L
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
N = 4.5 × 6.02 × 10²³
We have the final answer as
<h3>2.709 × 10²⁴ molecules</h3>
Hope this helps you
