Questions(Answer on an attached sheet of paper and turn in with the report) 1. Why do metals give off different colors in a flame test? 2. You spray paint the letters SPECTROSCOPY in yellow paint on snow. After a while the sun comes out and the snow under the yellow paint melts, leaving the letters in the word SPECTROSCOPY intact. Why did the snow under (rather than around) the yellow paint melt? 3. The graph below shows the absorption spectra...

Report Sheet: Post-lab Questions (pay attention to significant figures) 1) 50.00 mL of 0.20 M lead (II) nitrate solution was added to 30 mL of 1.25 M potassium iodide. These compounds react to form a lead (11) iodide, a bright yellow solid. Both solutions were at room temperature at the start of the reaction (19.6 'C). The final temperature of the reaction mixture was 22.2c. a. Write a balanced equation for this reaction. b. What is the theoretical yield of...

the
equation is what needs to be found from the graph using Boyle's
law.
1. Using the equation from your graph, calculate the pressure at 5.0 mL and at 10.0 mL. - 2. When the volume doubled, what happened to the pressure (as calculated above)? 3. From your answers to the first two questions and the shape of the curve in the plot of pressure versus volume, do you think the relationship between the pressure and volume of a confined...
Hi, answer all of these correctly. Thanks!

Please answer the following questions: 1)Graph the accompanying demand data, and then use the midpoint formula for Ed to determine price elasticity of demand for each of the four possible $1 price changes. Explain in a nontechnical way why demand is elastic in the upper segment of the demand curve and inelastic in the lower segment. Product Price Quantity Demanded $5 1 $4 2 $3 3 $2 4 $1 5 2)How would the following changes in price affect the...

Post-Laboratory Questions 1. For macroscale distillations, or for microscale distillations using glassware with elastomeric connec- tors, plot the data for simple distillation and for fractional distillation on one graph. Plot temperature on the vertical axis and total volume of distillate on the horizontal axis, as shown in Figure 6 earlier in this module. Draw a smooth curve through the data points for each distillation. 2. (a) At what temperatures were the first drop of distillate collected in the simple and...
