Answer:
The critical angle for the liquid when surrounded by air is 30 degrees.
Explanation:
Given that,
The angle of incidence is 33.5° and the angle of refraction is 19.3°. Firstly, we can find the refractive index of the liquid. It can be calculated using Snell's law as :
The critical angle is given by :
Here, 
is refractive index of air and 
is refractive index of liquid.
So, the critical angle for the liquid when surrounded by air is 30 degrees.
The correct statements are:
<span>- Elements are made up of only one type of atom.
- Each element has a unique chemical symbol.
- Elements can be identified by their atomic number.
In fact, elements are made up of only one tipe of atom, and each of them is identified by a different symbol. Moreover, each element has a different atomic number (number of protons), therefore elements can be identified by their atomic number.</span>
