Question

Please show work, I am stuck on this.

20) Specific heat capacity is a) the quantity of heat required to melt 1.00 g of a substance. b) the mass of a substance 1.00 J of energy will heat by 1.00 K. c) the mass of a substance 1.00 cal of energy will heat by 1.00 K. d) the temperature change undergone when 1.00 g of a substance absorbs 1.00 cal. e) the quantity of heat needed to change 1.00 g of a substance by 1.00 K. Letter answer to question #20: Part II: Short Answer / Calculation, 30 points total. Show all work! 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 → 1) MO(s) + CO2(g) What is the identity of the metal M? (10 points) EXTRA CREDIT (5 points): 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. Page 6 of 8 O \ 00 >

2) Menthol, C,H,O,, 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-', what is the empirical formula and molecular formula of menthol? (10 points) 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 HCI, 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 3) enc he reaction? (10 points) 8. Page 7 of 8 >
