Complete the following reactions, balance them and calculate how many grams of the first product you would get if you started with 5.0 g of the first reactant, assuming you have enough of the other
chemicals. SHOW WORK, including correct formulas, how you calculate molar mass and conversions
1. C2H5OH + O2  CO2 +
2. Magnesium hydroxide + hydrochloric acid --- magnesium chloride +
3. Ammonium carbonate - ammonia + + H2O
4. Copper(I)perchlorate + Zn -- Cu +
5. Nitrogen + hydrogen -- ammonia

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

If we compare and contrast electromagnetic waves with sound waves, all but one statement is true. that is a) sound waves require a medium to travel while electromagnetic waves do not. b) electromagnetic waves can travel through the vacuum of space while sound waves cannot. c) electromagnetic waves must have a medium in which to travel, but sound waves can travel anywhere. eliminate d) sound waves must bounce off of matter in order to travel while electromagnetic waves do not require matter to be present.
