Based on our knowledge of strong and weak acids, we can confirm that the Ka value for acetic acid will be relatively low since it is a weak acid.
Acids can be strong or weak. This is determined by its <u><em>tendency to break apart into ions or stay together to form molecules.</em></u> Although somewhat counter-intuitive, strong acids are those that are most likely to break apart and therefore contain a <em><u>high number of </u></em><em><u>ions </u></em><em><u>within their solutions</u></em>.
Weak acids, on the other hand, are those that<em><u> tend to stay together in the form of </u></em><em><u>molecules </u></em><em><u>and therefore possess very </u></em><em><u>low ion counts </u></em><em><u>in their solutions.</u></em> The acid dissociation constant, Kₐ, is used to measure whether an acid is weak or strong and how much so. In the case of Acetic acid, the ka measurement will offer a low value, indicating a weak acid.

They can distill the muddy water. This can be done by placing it in a can, covered with pipes to collect the boiling water, and then collecting the distillate. The fuel will be used to provide energy for distillation and the solid particles in from the muddy water will remain in the can as residue.
Density is the amount of matter within a given amount of space.
Water has a density of 1.0 gram per centimeter squared.
Mercury has a density of 13.6 grams per centimeter squared.
Thus, within the same volume, mercury has more mass than water. Thus, mercury has a higher density.
The answer is B. <span>The individual trials and the averages should each have their own columns in the data table.
In an experiment, you want to be able to see all of the data, so you should always include the data from each individual trial; however, it's important to have a separate column for averages, so you are able to compare all of the data.
Hope this helps! :)</span>
