In reaction between 100.0 grams of cac2 and calcium carbonate (excess), calcium hydroxide, ca (oh) 2, and ethylene gas c2h2 (also called acetylene) are formed. in the past, this response was used to light bicycle lights, lighthouses and more.
1) record the balanced response equation, including aggregate states.
2) what is the mass of ethin produced at the end of the reaction?
3) the reaction gas is transferred to a balloon at 20 ° c and a pressure of 2.00 atm. what is balloon volume? show calculations
4) what is the concentration of hydroxide ions at the end of the reaction, given that the solution volume is 500.0 ml?
5) ethin rarely dissolves in water, but calcium hydroxide dissolves well in water.
in contrast, ethin dissolves well in a two-sulfur carbon solution, but calcaneous calcium does not dissolve in carbon dioxide. explain.

What is the formula that this ionic compounds could form sr2+p3-o2-

Asolid that forms and separates from a liquid mixture is called

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.
