Explanation:
The student most likely observed both <u>(A) Vacuole</u> and <u>(C) Chloroplast</u> that led him to the conclusion, that the cell is a plan cell.
<u>Reason :</u>
In a plant cell, <u>Vacuole</u> occupies 70% to 90% of the total volume of the cell, making it easier to identify.
Chloroplast contains photosynthetic pigment called chlorophyll (green in colour), which is only found in plant cell.

C2H2O4 C2HO4- + H+
0.175 - x x x + y
C2HO4- c2o42– + H+
x - y y x + y
K2 = (y) (x +y) / (x-y)
As, y << x
So, K2 = (y) (x) / (x)
K2 = y =6.1 × 10^–5
Hence, concentration of (c2o42–) 6.1 × 10^–5 M
Answer : An atom is the smallest particle into which an element can be divided and still be the same substance.
Explanation :
Atom : It is the smallest unit of an element. Every atom is composed of a nucleus.
There are three sub-atomic particles present in every atom which are electrons, protons and neutrons.
The nucleus of an atom consist of protons and neutrons.
The electrons are revolve around the nucleus and are bound to the nucleus.
