Complete the following table, referring to the data table and question 1 as necessary. You will then plot the data in this table to determine the mole-to-mole ratio.

Maximum size for new files20.00MB Maximum attachments5 cloud_upload Drag and drop a file or folder here or click Using the data in the table above and a program like Excel, make a plot of mass of carbon dioxide produced vs mmol sodium bicarbonate including the 0,0 data point. The plot should have two distinct portions, an increasing portion on the left and a flat portion on the right. The mole-to-mole ratio will be determined from the intersection of the two lines. You will need to generate a trendline for each portion of the plot. In order to do this, you will need to identify at the transition point where the graph stops increasing and starts to flatten. Then generate a trendline for the left, increasing portion including the transition point and a trendline for the right, flat portion including the transition point. Record the slopes and y-intercepts of each trendline in the table below.

Be sure to show the trendline equations on your graph. A proper graph should fill a normal sheet of paper, have a title and labeled axes. The axes should be expanded to fit the range of your data (and not more). You can upload your graph directly (as a .xlsx, .csv, or .txt file) or upload a screen shot or photo of your graph (as a .pdf, .jpg, .png, or .heic file). Note: Hand drawn graphs are not accepted.
