You could add aquous hydrochloric to the solution to precipitate out silver chloride. what volume of a 0.130 m aqueous hydrochloric solution is needed to precipitate the silver ions from 30.0 ml of a 0.225 m silver nitrate solution? you could add solid potassium chloride to the solution to precipitate silver chloride. what mass of potassium chloride is needed to precipitate the silver ions from 30.0 ml of a 0.225 m silver nitrate solution?

1. list three scientific reasons cockroaches may fly.

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:

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.
