valerie placed 1.0g of salt into one beaker, 1.0g of soil into a second beaker, and 2.0g of sugar in a third beaker. She then added 200mL of water to each beaker and stirred the contents for 3 mintues. How many compounds and how many mixtures did Valerie make? Identify each. Explain whether a chemical or physical change took place in each beaker.
