How does the volume of the particles in a gas compare to the volume of the gas? a. volume of gas particles is larger than the volume of the gas c. volume of the gas particles is smaller than the volume of the gas b. volume of the gas is much smaller than the volume of the gas particles d. their volumes are equal as the gas particles are the gas

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

An electrons position cannot be known precisely only it's probability of being in a certain location can be known
