In a laboratory experiment, a fermenting aqueous solution of glucose and yeast produces carbon dioxide gas and ethanol. The solution was heated by burning natural gas in a Bunsen burner to distill the ethanol that formed in the flask. During the distillation, the ethanol evaporated and then condensed in the receiving flask. The flame of the burner was kept too close to the bottom of the flask and some of the glucose decomposed into a black carbon deposit on the inside of the flask. During this experiment the following changes occurred. Which of these changes involved a physical change and not a chemical change? Check all that apply. • View Available Hint(s) formation of a carbon deposit inside the flask O burning of natural gas formation of carbon dioxide gas from glucose condensation of ethanol formation of ethanol from glucose by yeast evaporation of ethanol

The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. Each compound is soluble in water. Imagine that a few tenths of a mole of each compound is dissolved in a liter of water. Then, write down in the third column of the table the chemical formula of the major chemical species that will be present in this solution. For example, you know water itself will be present, so you can begin each list with the chemical formula for water (H,O). 9- Note: "major" chemical species are those present in concentrations greater than 10 major species present when dissolved in water compound formula ロロ fructose H. magnesium sulfate *osân nitrous oxide O'N Ex anation Check O 2022 McGraw Hill LLC.

Matti is given two bottles of copper(II) sulfate solutions in her senior high chemistry lab. She is told that one bottle contains a saturated solution and the other one contains an unsaturated solution. The solutions are the exact same color and have no particles in the bottles. Describe what Matti can do to distinguish between the two solutions.
