David noticed that when he ate chocolates they melted in his hands faster when his hands were slightly wet from sweat than his hands were dry. He was curious to see if other liquids would affect how fast they would melt? He decided to test out four different liquids, water, milk, lemon-lime soda, and orange juice. He then timed how long it took them to melt. He thought the chocolate would melt faster in orange juice that the other liquids because it is more acidic. The results are below. QUESTIONS:
1) What was David's Question?

2) What was David Hypothesis?

3) What his independent Variable?

4) What his Dependent variable?

1.aluminum chloride (alcl3), and sodium hydroxide (naoh) can react to form aluminum hydroxide (al(oh)3) and sodium chloride (nacl).    you have 13.4 g of aluminum chloride and 10.0 g of sodium hydroxide. answer the following questions: •what is the balanced equation for this reaction? •if you use all 13.4 g of aluminum chloride, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •if you use all 10.0 g of sodium hydroxide, how many grams of aluminum hydroxide can be formed? work must be shown to earn credit •how many grams of aluminum hydroxide will actually be made?     which reagent is limiting? explain your answer.
