Many changes take place when substances react with one another to form products. For example, when acetic acid to sodium bicarbonate, the mixture becomes cold to the touch, and carbon dioxide gas is formed. Which of the following is true about the reactants and products of this reaction? The total mass of the products is equal to the total mass of the reactants

The products and reactants are chemically the same

The products and reactants both experience a physical change

The total mass of the products Is greater than the total mass of the reactants

What is the density of the black hole

If 22.5 liters of oxygen reacted with excess of hydrogen, how many liters of water vapor could be produced?

These questions are based on the attached photo. the experiment is about burning magnesium metal with oxygen. 1. write the balanced chemical equation for the reaction you are performing. 2. calculate the mass of magnesium metal used in each trial. o trial 1: o trial 2: 3. calculate the actual yield of magnesium oxide for each trial. o trial 1: o trial 2: 4. magnesium is the limiting reactant in this experiment. calculate the theoretical yield of mgo for each trial. o trial 1: o trial 2: 5. determine the percent yield of mgo for your experiment for each trial. o trial 1: o trial 2: 6. determine the average percent yield of mgo for the two trials. your company currently uses a process with a similar cost of materials that has an average percent yield of 91 percent. if the average percent yield of this process is higher than that, this could save the company money. what is your recommendation to the company? support your recommendation using your data, calculations, and understanding of stoichiometry gathered from this lab.
