Graphing is an important procedure used by scientist to display the data that is collected during a controlled experiment. There
astraxan [27]

Bar graph or bar chart displays data graphically using bars

The correct values are;

1. The independent variable is the <u>month</u> of the year

2. The dependent variable is the <u>number of deer</u>

3. The title is:  <u>The number of deer counted per month</u>

The reason the above values are correct are as follows:

<u></u>

In a tabular form is given as follows;

\begin{array}{|c|cc|}Month&&\# \ of \ deer \\Sept&&38\\Oct&&32\\Nov&&26\\Dec&&20\\ Jan &&15\\Feb&&12\end{array}\right]

A. Please find attached the required bar graph (chart) created with a desktop application

1. In an investigation to assign the cause of an effect is the cause of an effect, the independent variable is the causal variable responsible for the observed effect, and it is not affected by the effect. It is the variable that is not measured

In the given data, the month of the year is not affected by the number of deer, and it is not counted, to see if there is a change, therefore, the independent variable is the <u>month</u> of the year

2. The dependent variable, is the effect variable that is measured, and it depends on the dependent variable, which is the month

Therefore, the dependent variable is the <u>number of deer</u>

<u></u>

3. An appropriate title is one that captures the information intended to be obtained from the Bar graph

An appropriate title for the bar graph is; <u>The number of deer counted per month</u>

Calculate the pH of a 0.30 M NaF solution. The Ka value for HF is 7.2*10^-4
Licemer1 [7]
We are given with the equilibrium constant of acid, HF and is asked to calculate the pH of 0.30 M NaF solution. The formula to be followed is 
Ka = [H+][F-]/[HF]Ka = 7.2 x 10 -4 = x^2/[0.3-x]x = [H+]= pH = -log (H+) = 1.84
