Scenario 2: Marissa is an extremely curious sixth grader. During a snow day she looked out her window and saw a truck spreading something all over the road. After the truck went past Marissa's house, she had a snack, put on her snow boots, hat, coat and gloves and went outside to play. She walked over to the edge of her driveway and observed salt all over the roadway, but not the sidewalks or her driveway. She also observed some of the snow and ice had melted off the roadway but not her driveway or sidewalks. She wondered if the ice and snow melting was due to the salt? What is a possible testable question (in correct format) that Marissa might ask for this scenario?

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

(1) Slick Johnny burns 1.2 Kcal/min when he's completely chilled and fasted.  He lives on moonshine whiskey which is about 40% ethanol (assume a g is about an ml).  Assuming there isn't much else of nutritional value, how much would he have to drink to maintain his body weight. 0.62 L  0.82 L 0.93 L 1.44 L   (2) Assuming ethanol (C2H6O) is completely burned to CO2 and H2O, what would Slick Johnny's RQ be? 0.67 0.74 0.86 0.96

Solution 1 is diluted by adding 519 microliters of Solution 1 to 5 mL of Solution 2. What is the dilution of Solution 1?   Report your answer in standard decimal notation rounded to 2 decimal places. Include trailing zeros so that two decimal points are reported. For example, 500 μL added to 5 mL would be a 0.09 dilution or 50 μL added to 4.5 mL would be a 0.10 dilution.
