A circle graph, or a pie chart or graph, would be the type of graph that is best used when showing the <span>percentage of reactant molecules that collide during a reaction in a graphical representation. In addition, the circle graph mainly consists of a circle being divided into parts proportional to the whole.</span>

Answer:

Circle Graph

Explanation:

A scatter plot shows distribution of some numbers or properties versus another property. So it should be used for analysis of distribution or probability of something.

Stem and leaf plot are used when we have to show splitting of a stem ( a number) into leaves (another numbers).

So for percentage of reactant molecules colliding cannot be represented by scatter plot or stem and leaf plot.

In a circle graph or pie chart, we divide a circle (considering it to be 100%) into different parts based on fraction or percentage of each component.

For percentage of reactant molecule, we can divide the whole circle into two parts. One part showing the percentage of non reacting molecules and other part showing the percentage of reactant molecules undergoing collision.

Which graphic below shows the correct orientation of each water molecule when it is near the cl- ion in the aqueous solution?

The question is missing the graphics required to answer which I have attached as an image.

There are four different representations of the orientation of water molecules around chloride anion. Let's first analyze the water molecule.

We have H-O-H as the structure of water. The oxygen atom is more electronegative than the hydrogen atoms, which results in a partial positive charge on the hydrogen atoms and a partial negative charge on the oxygen atom.

The chloride anion is a negative charge. Therefore, the water molecules should orient themselves with the hydrogen atoms facing the chlorine atom as the partial positive charge on the hydrogen atoms will be attracted to the negative charge of the chlorine atom.

The correct representation is shown in graph 3 which shows all hydrogen atoms facing the chlorine anion.
