Maia is decorating her room by stringing twinkle lights around the edge of the ceiling. She was connecting two strands together when her older brother Dylan came in Dylan warned Maia not to connect the string lights together, because the more lights that are on the string, the dimmer each light would appear. Maia said that it didn't actually matter how many lights are on the string: they would all appear at full brightness. Maia handed Dylan the instruction manual. She pointed to the section that explained that these lights were made so that they could be connected. Who is correct?

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. 1-condensation of ethanol 2-evaporation of ethanol 3- formation of carbon dioxide gas from glucose burning of natural gas 4-formation of ethanol from glucose by yeast 5-formation of a carbon deposit inside the flask
