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.
Answer:
K = 4.07x10⁻³
Explanation:
Based on the reaction:
NH₄I(s) ⇄ NH₃(g) + HI(g)
You can define K of equilibrium as the ratio of concentrations of reactants and products, thus:
K = [NH₃] [HI] / [NH₄I]
But, as NH₄I is a solid, is not taken into account in the equilibrium, that means K expression is:
K = [NH₃] [HI]
As the concentrations in equilibrium of the gases is:
[NH₃] = 4.34x10⁻²M
[HI] = 9.39x10⁻²M
Equilibrium constant, K, is:
K = 4.34x10⁻²M * 9.39x10⁻²M
<h3>K = 4.07x10⁻³</h3>

Explanation:</h2><h3>average atomis mass.....(<u>75.77 × 34.97 + 24.23×36.96 ) ÷100</u> and answer should be 35.452</h3>
The complete question; At atmospheric pressure a balloon contains 2.00 l of nitrogen gas, how would the volume change if the kelvin temperature was only 75 % of its original value?
The change in volume would be;
original volume × percentage
= 2 ×0.75 = 1.5 L
Thus the volume would change by 1.5 L
Answer: 32.06 atomic mass units
