1) 1.056 g of metal carbonate, containing an unknown metal M, were heated to give the metal oxide and 0.376 g CO2. The equation: MCO3(s) + heat → MO(s) + CO2(g) What is the identity of the metal M?
Please Show all work attach a picture of the work you did on a piece of paper it's much easier to understand and follow it that way. Thank you in advance
1) 1.056 g of metal carbonate, containing an unknown metal M, were heated to give the metal oxide and 0.376 g CO2. The
equation: MCO3(s) + heat → MO(s) + CO2(g) What is the identity of the metal M?
EXTRA CREDIT : The weight percent of oxygen in an oxide that has the formula E2O3 is 11.20%. Calculate the atomic weight of element E. Using the periodic table, state the identity of E.
2) Menthol, CxHyOz, is a strong-smelling substance used in cough drops and cigarettes. When 0.1595 g menthol was subjected to combustion analysis, it produced 0.449 g CO2 and 0.184 g H2O. If the molar mass of menthol is 156.3 g mol-1, what is the empirical formula and molecular formula of menthol? (10 points)
3) Calcium carbonate reacts with hydrochloric acid solution to form calcium chloride solution, water and carbon dioxide. Write the balanced equation. If 10.0 g of CaCO3 reacts with 80.0 mL of 2.74 M HCl, what is the theoretical yield of carbon dioxide if 3.65 g of CO2 is collected? What is the percent yield? Which reagent is in excess? How much excess reagent is left at the end of the reaction?
