Classify the following: the number of books owned by a student.

A scientist is analyzing the traveling speeds of a sample of 40 cars on a highway (using mph). Here is the summary of the data: Classify the statement: About 75% of sampled cars on a highway had travelling speeds faster than 60 mph.

MATCHING: Use the periodic table to identify the element with the following electron configuration.

The amounts of coffee dispensed from the vending machine follow a bell-shaped symmetric distribution.  In a sample of 50 cups of coffee dispensed from the vending machine, the mean amount dispensed was 7.6 ounces with a standard deviation of 0.2 ounces. Classify the statement: About 2.5% of sample cups dispensed from the vending machine have more than 8 ounces of coffee.

Description: For each chemical equation (which may or may not be balanced), list the number of each type of atom on each side of the equation, and determine if the equation is balanced.  List the number of each type of atom on the right side of the equationC3H8(g) + 3O2(g) → 3CO2(g) + 4H2O(g) Enter your answers separated by commas (the order of the numbers is the same as the order of the elements on the left side of the equation).

In the Bohr model, what happens when an electron makes a transition between orbits?

What are the products of the balanced equation for the combustion of C8H17OH?

A quality control scientist was interested to study the actual amount of soda (in ounces) in a standard 12-oz can.  He analyzed a random sample of 24 such cans.  The following numerical summaries were computed.  Which of the following is the proper interpretation of the mean (in the context of the problem)?

Consider the reaction between HCl and O2: 4HCl(g)+O2(g)→2H2O(l)+2Cl2(g) When 63.1 g of HCl is allowed to react with 17.2 g of O2, 46.0 g of Cl2 is collected. You may want to reference (Pages 260 – 264) Section 8.6 while completing this problem. Determine the theoretical yield of Cl2 for this reaction. Express your answer as a chemical formula.
