Problem- How many significant figures can you accurately report in the values for Ksp that you calculated in Parts 2 and 3 of the experiment? Are the two values different from each other to that number of significant figures?
Please answer only if you are 100% confident
Consider the temperature change, together with the volume and concentration of the acid and base, noted in the HAZMAT team's response regulation information(50mL 1M HCl,50mL 1M NaOH,change in temp = 6.7C).
Explain why acid chlorides can be used to prepare amides but amides are not generally used to prepare acid chlorides?
