2. Assume the reaction is: $$ 2 \mathrm{NaHCO}_{3}(\mathrm{~s}) \rightarrow \mathrm{Na}_{2} \mathrm{CO}_{3}(\mathrm{~s})+\mathrm{CO}_{2}(\mathrm{~g})+\mathrm{H}_{2} \mathrm{O}(\mathrm{~g}) $$ What mass of $\mathrm{NaHCO}_{3}$ (s) must have been present at the beginning of the reaction? # Hide Hint Hint: Your goal is to do the steps you'd did in the previous section, but in reverse. You know the mass of the $\mathrm{Na}_{2} \mathrm{CO}_{3}$ product: 3.78 g The molar mass of $\mathrm{Na}_{2} \mathrm{CO}_{3}$ is $105.99 \mathrm{~g} / \mathrm{mol}$ The molar mass of $\mathrm{NaHCO}_{3}$ is $84.01 \mathrm{~g} / \mathrm{mol}$ How can you use this information to find the mass of the initial amount of $\mathrm{NaHCO}_{3}$ ?

This process is called cellular respiration. This process is dependent on photosynthesis and, since plants perform both processes, we call them autotrophs. Animals are heterotrophs as they need to consume their food from different sources. Use the chemical equations below to answer the questions once you have discussed each other's individual data. You may also want to revisit the data from the activity you did previously called "A Plant's Raw Materials."

# Question 10 (1 point) When the price of peanut oil falls from $\$ 5$ to $\$ 4$ per gallon, quantity demanded increases from 8 to 10 gallons per month. Based on this information, the absolute value of the price elasticity of demand using the midpoint method is $\square 1.25$ and demand is relatively inelastic. $\square 1.0$ and demand is unit elastic. $\square 1.25$ and demand is relatively elastic. $\square 0.8$ and demand is relatively elastic. ## Question 11 (1 point) Suppose that you are the owner of a dairy mart. You receive revenues from sales of soda and potato chips. If the cross-price elasticity of demand between the two products is -0.87 and you lower the price of soda, then demand for potato chips $\square$ is indeterminable. $\square$ does not change. $\square$ increases. $\square$ decreases.

## **2. Cow Tipping (2 pts)** In 2005 Dr. Margo Lillie and her student Tracy Boechler published a study claiming that cow-tipping (the act of knocking a standing cow over by pushing on its side) cannot be performed by one person alone. You'll perform the same analysis here. Assume that a typical cow (see figure) has a mass of 680 kg, with a center of mass located as shown. Also assume that you push the cow horizontally at the point indicated in the figure. a) Draw a free-body diagram of the cow when a person is pushing it. b) Calculate the magnitude of the minimum force the tipper would need to exert to tip the cow. Do you think it would be reasonable for a single person to exert this force?
