Answer:
d) 0.1202 M
Explanation:
Let's consider the neutralization reaction between NaOH and a generic monoprotic acid.
NaOH + HA → NaA + H₂O
The used volume of NaOH is 41.63 mL - 19.63 mL = 22.00 mL. The moles of NaOH are:
22.00 × 10⁻³ L × 0.1093 mol/L = 2.405 × 10⁻³ mol
The molar ratio of NaOH to HA is 1:1. The moles of HA that reacted are 2.405 × 10⁻³ moles.
The molar concentration of HA is:
2.405 × 10⁻³ mol / 20.00 × 10⁻³ L = 0.1202 M
Should be all of the above (A)
Hello! I believe you are asking what a Cell wall Is.
Answer:
<em> A rigid layer of nonliving material that surrounds the cells of plants and some other organisms.</em>
Explanation:
A cell wall is<u><em> a sturdy outer layer of protection of the plant cell. It protects the cell membrane and other organelles from the environment, bacteria, and viruses</em></u>. It is composed of cellulose, lignin, and suberin interspersed with carbohydrates and proteins.
Hope this Helps!
