General Chemistry II Laboratory Manual, 2021 Revision 39 Questions: 1) When you set up the temperature probe using Capstone, you did not calibrate it to read the correct temperature. It's possible that the probe reads temperatures that are consistently off by 1 or 2°C. Why won't this affect your results for this experiment? Explain your answer.

Expressing amounts of energy in different energy units is necessary to solve many chemistry problems. For practice, complete the following table. The Joule (J) is the SI unit of energy. 1 calorie (cal) = 4.184 J 1 kWh = 3.600 x 106 J J 202 kWh 199 kcal 226
Read the descriptions below of two substances and an experiment on each. Decide whether the result of the experiment tells you the substance is a pure substance or a mixture, if you can. . Sample A is 100. g of a coarse grey powder with a faint unpleasant smell. 15. g of the powder is put into a funnel lined with a sheet of thick paper. Distilled water is poured slowly over the powder. All of the powder disappears, and the water under the funnel turns a deep purple. . Sample B is 100. mL of a clear liquid. The density of the liquid is measured, and turns out to be 0.77 g/mL. The liquid is then cooled in the refrigerator At 10.0 °C crystals begin to appear. The temperature of the liquid continues to decrease as more crystals form, until at 6.2 °C the liquid is entirely solid. Is sample A made from a pure substance or a mixture? If the description of the substance and the outcome of the experiment isn't enough to decide, choose "can't decide." Is sample B made from a pure substance or a…
