ANSWER
Heterogeneous mixture
EXPLANATION:
Given information
From the above image, we can see that we have three elements named a, b, and c. The elements a and c are attached to each other while element b can move freely.
Recall that, the combination of two or more elements is called a compound.
The above image shows the combination of a compound and an element
Hence, we can say that it is a heterogeneous mixture
Answer:
The correct answer is option A.
Explanation:
Energy of the photon of an electromagnetic radiation is give by Planck's equation:
Where:
h = Planck's constant
c = speed of light
= Wavelength of the photon's radiation
Energy of photon of 800 nm monochromatic light
Energy per mole of photons:
..[1]
Energy of photon of 400 nm monochromatic light
Energy per mole of photons:
..[2]
[1] ÷ [2]
Answer: s (solid), l (liquid), g (gas), aq (Aqueous)
Aqueous is for when something has dissolved in water and given the symbol aq
