Centrifugation is used to separate the suspended particles in solution.
<u>Explanation:</u>
- The method of centrifugal action commonly referred to as "Centrifugation" is majorly used to effectively separate the suspended particles from the solution by means of rotating the sample at the maximum speed.
- When the samples gets rotated at the maximum speed the suspended particles settles down at the bottom and it can be filtered using the filter paper,thus resulting in the separation of suspended particles in the solution.
- However this techniques cannot be used for the substances dissolved in solution.

I will draw how the city looks like
Answer:
n = 0.413moles (3 sig-figs).
Explanation:
From definition of molarity, solve for moles and substitute given data.
Molarity(M) = Moles Solute(n)/Volume of Solution in Liters(V)
M = n/V => n = M·V => 0.330moles/Liter x 1.25Liters = 0.4125moles ≅ 0.413moles (3 sig-figs).
Answer:
Love is not only the thing in this world!
Study hard, you can choose a better way of life.
A chemical change is one where the compounds are modified: a compound decomposes into its elements, or combine with other elements to form a different compound.
That is what happens when a match burns: oxygen reacts with the match compounds and form CO2(g), H2O(g) and other compounds depending on the composition of the match.
The other processes only involve a physical change of the compounds, but they remain being the same compounds (same elements with the same bonds).
Answser: option 1. the burning of a match.
