Beaker directions: • Measure the liquid in the beaker. Look at what the lines stand for (these are very limited in their ability to measure). Account for all digits on the instrument and then add 1 estimated digit. • If there is not a line for a place value (1, 2, 3...), then that is the furthest you can estimate! 100 80- 60 40 20

Although your textbook lists (he rules for converting an ordinary number to scientific notation, oftentimes students remember such rules better ¡f they put them into their own words. Pretend you are helping your 12-year-old niece with her math homework, and write a paragraph explaining to her how to convert the ordinary number 2421 to scientific notation.
As part of a science project, you study traffic patterns in your city at an intersection in the middle of downtown. You set up a device that counts the cars passing through this intersection for a 24-hour period during a weekday. The graph of hourly traffic looks like this. At what lime(s) does the highest number of cars pass through the intersection? At what time(s) does the lowest number of cars pass through the intersection? Briefly describe the trend in numbers of cars over the course of the day. Provide a hypothesis explaining the trend in numbers of cars over the course of the day. Provide a possible experiment that could test your hypothesis.
The density of an irregularly shaped object was determined as follows. The mass of the object was found to be 28.90 g 0.03 g. A graduated cylinder was partially filled with water. The reading of the level of the water was 6.4 cm3 0.1 cm3. The object was dropped in the cylinder, and the level of the water rose to 9.8 cm3 0.1 cm3. What is the density of the object with appropriate error limits? (See Appendix 1.5.)
According to the Official Rules of Baseball, a baseball must have a circumference not more than 9.25 in or less than 9.00 in and a mass not more than 5.25 oz or less than 5.00 oz. What range of densities can a baseball be expected to have? Express this range as a single number with an accompanying uncertainty limit.

The compound cyclohexanol, C6H120, is a good fuel. It is a liquid at ordinary temperatures. When the liquid is burned, the reaction involved is 2 C6H120(t) + 17 02(g)→12 CO2(g) + 12 H20(g) The standard enthalpy of formation of liquid cyclohexanol at 25 °C is -348.2 kJ mol-1; other relevant enthalpy of formatton values in kJ mol1 are: C6H120(g) = -286.2 ; CO2(g) = -393.5 ; H20(g) = -241.8 (a) Calculate the enthalpy change in the burning of 3.000 mol liquid cyclohexanol to form gaseous products at 25°C.
