Scenario: jimmy john the 3rd created a soda pop recipe called "wings that makes red bulls fly. to prove
his claim, he creates two test groups of 10 red bulls with a local rancher. group one received "wings"
three times a day for one week and group two received blue sugar water three times a day for one
week. jimmy john the 3rd recorded the following results from his experiment:
number of red bulls that flew
number of red bulls that did not fly
soda type
"wings"
blue sugar water soda

question 3 (2 points). what is the independent variable in this scenario?
question 4 (2 points). what is the dependent variable in this scenario?
question 5 (2 points). what is the control variable in this scenario?
question 6 (2 points). what could jimmy john the 3rd conclude about his "wings” recipe?
question 7 (2 points). why did one red bull that drank the blue sugar water soda fly? what could have
happened?

1. combine iron and copper (ii) sulfate solution. (hint: iron will form the iron (iii) ion) fe + cuso4 → 2. combine lead (ii) nitrate and potassium iodide solutions. pb(no3)2+ kl → 3. combine magnesium metal and hydrochloric acid solution. mg + hcl → 4. electrolysis (splitting) of water. h2o → 5. burning magnesium. mg + o2 →

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
