Determine the temperature change expected when 2.07g of ethanolare burned in a bomb calorimeter whose heat capacity (as previously measured) is 9007J/K at 25 ̊C. A 23.74g sample of molten tin at its melting point (232 ̊C) is placed into a 108 g sample of water initial at 21 ̊C. Assuming that none of the water is vaporized, predict the...
A study of obesity risk in children in a head start program used a food score calculated from a 45‑question food survey to predict body mass index (BMI) percentile in these children 18 months after the initial survey. The study enrolled 20 children. The researchers used a linear regression model for the prediction of BMI percentile. The food scores ranged...

When ethane (C2H6) reacts with chlorine (Cl2), the main product is C2H5Cl; but other products containing Cl, such as C2H4Cl2, are also obtained in small quantities. The formation of these other products reduces the yield of C2H5Cl. a. Calculate the theoretical yield of C2H5Cl when 111 g of C2H6 reacts with 207 g of Cl2, assuming that C2H6 and Cl2...
