1. Given that a theoretical yield for isolating Calcium Carbonate in this experiment would be 100%. From that information and based on the results you obtained in this experiment, describe your success in the recovery of calcium carbonate and suggest two possible sources of error that would have caused you to not obtain 100% yield. from my result my percent yield was 102%

Part 1 A student carried out an investigation to observe the effect of changing concentration of sulfuric acid on the breakdown of calcium carbonate (marble) chips. They changed the concentration of the acid between each test but kept the size of the marble chips constant. The full equation for the reaction and a graph of the overall results can be seen below. CaCO3(s) + H₂SO4(aq) → CaSO4(aq) + CO2(g) + H₂O (1) a) b) Rate of Reaction * Concentration of Acid (mol dm³) Explain, using collision theory, why the student obtained these results, and state what they could conclude about the effect of changing concentration of acid on the rate of reaction between calcium carbonate and sulfuric acid. If the student had ground up the calcium carbonate chips into a powder and run the tests again, what would you expect to happen to the rate of reaction? Briefly explain why by applying collision theory. Part 2 The student ran the same experiment, but this time changed the temperature, increasing it…

Magnesium +Acetic Acid --> C2HG5+ O2 ---> Iron (III) carbonate -->

In today’s experiment, a combination reaction of magnesium and oxygen is used to determine the empirical formula ofmagnesium oxide.  After the experiment, I need to answer the fellow two questions: #1; There is one major competitive side reaction that may reduce the accuracy of your results in this experiment. Consult the Internet to research, describe and write a balanced equation for this side reaction. (HINT: What component of air other than oxygen could be responsible?) #2; My Professor asked me match are empirical formula of magnesium oxide from my experiment with the actually one by searching it on the internet. My empirical formula of magnesium oxide from my experiment is Mg4O3 and I look up on the internet is MgO. So, I have to find out why they are different  Please help me question #1,2 thank you very much
