A scientist collected the following data, which show how the pressure of water vapor changes with temperature. Temperature (°C) Pressure (mm Hg) 0 4.5 10 9.6 20 19.1 30 33.2 40 58.7 50 95.6

What would a scientist do to best communicate these data to other scientists in a presentation?

Replace the table with text highlighting pressures.
Change the unit of pressure to atm.
Make a graph for better visual representation.
Display only rows 1, 3, and 6 of the data to simplify results.

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

1. explain hydrogen peroxide, h 2 o 2 properties and decomposition reaction. 2. describe how each of the following natural cycles plays a part in earth’s climate system. (a) the water cycle (b) the carbon cycle

Some animals that try to adapt to climate changes eventually die due to starvation, as climate change alters the web.
