What is important to remember while one is using heat inside the laboratory? * Before using a Bunsen burner, make sure that there are no flammable materials scattered around the laboratory table. In heating a beaker, the beaker should be placed directly on top of the Bunsen burner, without support. You can use your hand to hold the hot container as long as you have a thick laboratory gown. The vapor of the substance being heated can be inhaled directly by sniffing the mouth of the container. In dealing with chemical spills from broken glass apparatus inside the laboratory, which of the following should be done first? * O Cry for a long time and feel miserable. Throw the glass into the nearest trash bin and let the spill air-dry. Clean up the spill with water and paper towels, then place the broken test tube in the disposal container provided by the instructor for sharp objects. Throw away the glass quickly, clean up the spill with the nearest cloth, and pray no one sees.

Assume the data below was collected for two different sample solutions using the same experimental procedure you carried out. Based on the two lines shown below, which solution (orange data points or blue data points) corresponds to the sample that would look DARKER in terms of how much light goes through the glass. 0.9 y= 4.7713x - 0.0728 R0.99953 0.8 0.7 0.6 0.5 0.4 0.3 0.2 y1.414x - 0.0546 R0.99642 0.1 0.02 0.04 0.06 0.08 0.1 0.12 0.14 0.16 0.18 0.2 0.1 [Concentration, M] orange data points (lower line) blue data points (upper line) Absorbance
