Answer:
In order of decreasing miscibility
C₉H₂₀ (nonane)→C₂H₅F (fluoroethane)→C₂H₅Cl (chloroethane)→H₂O (water)
Explanation:
The solubility of a solid is a measure of its ability to dissolve in a liquid while for liquids, the miscibility is a measure of thhe liquid to mix with anoyjer liquid resulting in a soltion which can hold any amount of either liquids. Immiscible liquids are those that are not soluble or have very limited solibility with each other.
C₉H₂₀ (nonane)→C₂H₅F (fluoroethane)→C₂H₅Cl (chloroethane)→H₂O (water)
In the order of decreasing miscibility as like dissolve like, ability to dissociate and polar and organic characteristics are considered
<u>Answer:</u>
17%
<u>Explanation:</u>
Mass of a piece of copper calculated by student = 8.3 grams
Actual mass of copper = 10 grams
We know the formula for the percent error:
Percentage error = (| experimental value - actual value | / actual value) * 100
So substituting the given values in the above formula:
Percent error = (|8.3 - 10| / 10) * 100 = (1.7/10) * 100 = 17%
First of all, we need tô calculate moles of KCl
next, mass=mol×molar mass
