- pH = 11.7 Express your answer using one significant figure. [H3O+][H3O+] = MMDr. Colibrí studies hummingbirds. Each bird requires approximately 9.52 milliliters of nectar every day to stay alive. Synthetic nectar solution is made by mixing 20%(vol/vol) sucrose with 80%(vol/vol)water. Sucrose, common table sugar, has a density of 1.59 g/mL. How many grams of sugar does Dr. Colibri need to keep 7 hummingbirds alive for 63 days? (answer to 2 decimal places) Assumption: When mixing 1 part sugar with 4 parts water, the combined volume does not change. e.g. 200 mL of sugar combined with 800 mL water will produce 1000 mL of nectar. This is technically untrue, but it is close enough for our purposes.Question 11 .A sample of Fluorine occupies 65.5 mL at 23.0 oC. Calculate the final volume in mL when the temperature increased to 62.5oC. The final answer is... use the G.U.E.S.S. Method format.

Excel graphs are not permitted. Your graph should have: a titie, proper axis scaling, axes labelled including units, data points shown clearly eg. dot in a circle, best straight line drawn, and the coordinates (x,y) of the points on the straight line chosen to calculate the slope. Never use data points to calculate the slope! Show slope calculation directly on the graph. 3. a) From your graph, calculate the experimental value of R, the Rydberg constant. (Note - this is the absolute value of your slope): b) Based on the theoretical value of R,1.0974×107 m−1, calculate your % error: information you need to solve this question: The picture is attachedHow many mL of 12% SDS would you need to make 23 mL of 2 % SDS?

If he drives an extra eight miles (round trip) to a gas station on the outskirts of town, Stan can save $0.10 per gallon on the price of gasoline. Suppose gasoline costs $3.90 per gallon and Stan’s car gets 25 mpg for in-town driving. Should Stan make the trip to get less expensive gasoline? Each mile that Stan drives creates one pound of carbon dioxide. Each pound of CO2 has a cost impact of $0.02 on the environment. What other factors (cost and otherwise) should Stan consider in his decision making?from lowest to highest, 4 being the lowest
