Two liquids- one polar, one nonpolar- have the same molar mass. Which one has the higher boiling point?
victus00 [196]

Answer:

D. the polar liquid will have the higher boiling point, since its molecules have dipole-dipole interactions.

Explanation:

<em>Dipole-Dipole interactions</em> take place only between polar molecules.

They consist of attractions between the negative end of a polar molecule and the positive end of another polar molecule. For example, between the O atom and the H atom in water.

These attractions are not present in a non-polar liquid, so its molecules will be more loosely held together and its boiling point will be lower.

Which scatterplot shows the correct division for using the Divide-Center of Data method to draw the trend line?
nlexa [21]

The appropriate scatter plot that depicts the correct division for using Divide center to draw trend line is the plot D.

<h3>What are Scatter plots?</h3>

Scatter plots are used to show how much one variable affects another by plotting data points on a horizontal and vertical axis. Each row in the data table is represented by a marker, the position of which is determined by the values of the columns set on the X and Y axes. Scatter plots are graphs that show the relationship of two variables in a data set. It is a two-dimensional plane or a Cartesian system that represents data points.

In order to draw a trend line correctly, divide the points using the divide center method. The dividing vertical line must be drawn at the midpoint (a position where the number of data points to the left and right of the vertical line is equal).

Only option D has a vertical line dividing the 6 data points into two equal portions when the options are evaluated based on this condition.

The diagram is attached.
