5. Explore: You can find the volume of an object using just a graduated cylinder if you don't have access to an overflow cup. This technique works if the object you are measuring is

small enough to fit into the graduated cylinder.

Return the overflow cup and the 25-ml graduated cylinder to the cabinet. Take out the

100-ml graduated cylinder and the pipette. Fill the 100-ml graduated cylinder to exactly

40.0 mL, using the beaker and the pipette.

A. Drag the rock into the 100-ml graduated cylinder. Use the magnifier to read

the new volume. What is the current water volume in the graduated cylinder?

B. How much has the water volume changed in the graduated cylinder?

C. Based on your answers to A and B, what is the volume of the rock?

If you burn 10 kilograms of wood in a fire (combustion) what is the weight of the products after the fire has finished burning the wood?

Part b: study of equilibrium on solubility: mg(oh)2(s) ⇌ mg2+(aq) + 2 oh–(aq) cloudy clear (pink) 7. a. b. 8. a. b. 9. 10. 11. 12. when adding concentrated hydrochloric acid, how did the appearance of the equilibrium mixture change? the change in appearance indicated a shift in the point of equilibrium. in which direction did the equilibrium shift? (l) left (r) right explain your answer to question 7a. you should indicate which ion was added to or removed from the equilibrium mixture. when adding edta, how did the appearance of the equilibrium mixture change? the change in appearance indicated a shift in the point of equilibrium. in which direction did the equilibrium shift? (l) left (r) right explain your answer to question 8a. you should indicate which ion was added to or removed from the equilibrium mixture. upon heating in which direction is the equilibrium shifting? upon cooling in which direction is the equilibrium shifting? is the forward reaction a. endothermic explain your answers to questions 9, 10, and 11. (l) left (r) right (l) left (r) right b. exothermic
