Liquid octane (CH(CH).CH,) will react with gaseous oxygen (02) to produce gaseous carbon dioxide (Co,) and gaseous water (1,0). Suppose
51. g of octane is mixed with 150 g of oxygen Calculate the maximum mass of water that could be produced by the chemical reaction. Be sure your
answer has the correct number of significant digits​

Which of the following is a compound? a. carbon b. oxygen c. hydrogen d. water

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

The formation of a solid, also known as a is an indication of a chemical change. precipitate particulate particle powder
