4) is correct
This is because water is polar and it will mix with a polar solvent. A good rule for remembering the behavior of non-polar and polar compounds when it comes to being miscible is that "like dissolves like."
Answer:
wavelength = 6×10⁻⁷m
f = 0.5 ×10¹⁵ Hz
Explanation:
Given data:
Energy of photon = 3.2×10⁻¹⁹ J
Wavelength of photon = ?
Frequency of photon = ?
Solution:
E = h.f
f = frequency
h = planck's constant
E = energy
f = E/h
f = 3.2×10⁻¹⁹ Kg.m².s⁻²/ 6.63×10⁻³⁴ m².Kg/s
f = 0.5 ×10¹⁵ s⁻¹
s⁻¹ = Hz
f = 0.5 ×10¹⁵ Hz
Wavelength:
speed of light = wavelength × frequency
wavelength = speed of light / frequency
wavelength = 3×10⁸ m.s⁻¹ /0.5 ×10¹⁵s⁻¹
wavelength = 6×10⁻⁷m
B. a sugar crystal
Because sugar comes from plants, it is classified as an organic compound, not a mineral.
The study and understanding of the biological macromolecules impact our everyday life by making us know what to eat and the different processes which occur in the body.
<h3>What are Biological macromolecules?</h3>
These are cellular components of the body which are natural and vital for the growth and survival of organisms.
Examples include carbohydrates, protein etc which contain nutrients vital for our daily life.
