Kayla is creating a model to show her understanding of the water cycle. She wants to show that water is constantly cycling between the atmosphere and Earth’s surface. What would be the BEST type of model for Kayla to create.

A 3-D model of H2O created with gumdrops and toothpicks.

A. A diagram of molecules gaining energy as they being to evaporate and enter the atmosphere.

B. A poster with pictures of lakes, oceans, rivers and ponds.

C. A circular diagram with arrows showing the movement of water between Earth’s surface and atmosphere.

Achemist wants to extract copper metal from copper chloride solution. the chemist places 0.50 grams of aluminum foil in a solution containing 0.75 grams of copper (ii) chloride. a single replacement reaction takes place. (ii) chloride. a single replacement reaction takes place. which statement explains the maximum amount of copper that the chemist can extract using this reaction? a) approximately 0.36 grams, because copper (ii) chloride acts as a limiting reactant b) approximately 1.8 grams, because copper (ii) chloride acts as a limiting reactant c) approximately 0.36 grams, because aluminum acts as a limiting reactant d) approximately 1.8 grams, because aluminum acts as a limiting reactant
