Whenever quantities of two or more reactants are given in a stoichiometric problem, you must identify the __1__. This is the reagent that is completely __2__ in the reaction. The amount of limiting reagent determines the amount of __3__ that is formed. When an equation is used to calculate the amount of product that will form during a reaction, the value obtained is the __4__. This is the __5__ amount of product that could be formed from a given amount of reactant. The amount of product that forms when the reaction is carried out in the laboratory is called the __6__.

Iknow #2 is d. i just need to know why

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
