67. The Final Jeopardy Category is: Separating a Mixture Please record your wager. Click on screen to begin

68. Christie made a dry mixture out of Legos, calcium citrate (crushed up chalk), and citric acid. She added 50 ml of water to her mixture. She wants to separate them in order: first Legos, second calcium citrate, and last citric acid. She has an evaporation dish, a screen, and a filter. Write the steps she should take to separate her mixture. Click on screen to continue
