A 106.2 mL sample of 0.100 M methylamine ( CH3NH2; Kb = 3.7 x 10-4) is titrated with 0.235 M HNO3. Calculate the pH after the addition of each of the following volumes of acid.

Can you help with 13. This is not a graded question as it is a practice question . I am 60 years old and helping my son prepare for the AP exam in a few months. We do questions at the back of the textbook by Zumdahl and Zumdahl

Based on the information given, identify the most significant error in the preparation of Graph 2.     A)  The title appears in a font which is too small.   B)  The best-fit line does not intersect any data point.   C)  There is wasted space on the graph.   D)  The x-axis scale divisions are uneven.

I’m not sure how to do this type of chemistry Also if you need the ingredients it’s the second pic

I cannot figure this question out. I cannot find any one of these numbers that has 3 significant figures, and when I say that 200 has 1 I get it wrong.

how can i plot this data for concentration with depth?

Please show me how you got the correct answer for question 2 step by step

Suppose your instructor places a can of regular and diet cola in a large container filled with water. What might you expect happen based on the results of this experiment?

Using a 25mL pipette, you prepare a standard solution by pipetting 25.00mL of the standard iron solution[0.25g/L] into a 500mL volumetric flask. Then, using a 10mL pipette you transfer a 4mL aliquot of this solution into a 50mL volumetric flask and dilute up to the mark. Calculate the % uncertainty.   Question 1 options:   0.65   0.75   0.0075   0.45

The Covid-19 pandemic has many experts commenting on the science associated with the virus - origins, vaccines, monoclonal antibodies, masks, social distancing.  It is important to consider what the experts say, but to also evaluate their statements.  We will start with the scientific method.  I want you to outline the scientific method from what you have been taught in previous classes.  You can list steps, parts, process, short descriptions, whatever.  If not taught in previous classes, then you will make your best guess about it.

Chemistry. The best fit line is y = 1.03892x + 0.1448   1) If a sample had an absorbance of 0.333, what would be the concentration? 2) If a sample had a concentration of 0.40 mg/ml, what would be the absorbance?
