When scientists conduct an experiment and analyze the results, the next step is to write up a report that describes the experiment and the results and submit it for publication in a scientific or medical journal that is “peer reviewed.”
First take all percents and make them grams. Since you're not given a overall molar mass you can assume it is 100 and therefore the percents are their masses.
So you have 14.31g Carbon, 1.2g Hydrogen, and 84.49g of Chlorine. Next you divide each by their molar masses to get moles of each.
Carbon= <u>14.31</u>g Hydrogen= <u>1.2</u>g Chlorine= <u>85.49</u>g
12.01g 1.01g 35.45g
= 1.19moles = 1.188moles = 2.411moles
Next you divide each of those numbers by the smallest, in this case, Hydrogen.
Thus,
Carbon= <u>1.19moles</u> Hydrogen= <u>1.188moles</u> Chlorine= <u>2.411moles</u>
1.188moles 1.188moles 1.188moles
=1.002 =1 =2.02
These are all close enough to round, so your final empirical formula is: CHCl2
Hope that helps!!
Explanation:
A mixture which shows presence of uniform composition of solute particles into the solvent is known as a homogeneous mixture.
- Distilled water is a clear solution in which there is uniform composition of solute particles into the solution.
- Gasoline is mixture of different compounds which are evenly distributed. Therefore, it is also a homogeneous mixture.
- Wine is also a clear solution in which particles are evenly distributed. Hence, it is a homogeneous mixture.
On the other hand, a mixture which shows non-uniform composition of solute particles into the solvent is known as a heterogeneous mixture.
- Beach sand is a mixture of different particles present in varying composition. Hence, it is a heterogeneous mixture.
- Also, in air there are different gases present in different composition. Mover over, there is presence of fog and smoke into the air. Hence, it is a heterogeneous mixture.
