Mixture of calcium carbonate and magnesium carbonate is called Dolomite. Dolomite decomposes to CO₂ and the metal oxides MgO and CaO upon heating. When 10.04 g of dolomite is heated, 5.12g of MgO and CaOare produced. Calculate the percent by mass of MgCO3 in the original sample of dolomite. 19.0% 61.8% 75.0% 25.5%

Which of the following statements is false concerning the reaction of hydrogen gas and oxygen g below? H₂(g) + O₂(g) → H₂O(); AH = -285.8 kJ Per mole of O2, the change in enthalpy is -571.6 kJ. The value-571.6 kJ pertains to 1 mol of liquid water. O If the equation is multiplied by 2, AH becomes -571.6 kJ. O For the reaction H₂(g) + O2(g) → H₂O(g), AH is not equal to -285.8 kJ. If the equation is reversed, AH becomes +285.8 kJ.
Sodium hydrogen sulfate is used as a cleaning agent and as a flux (a substance that promotes the fusing of metals and prevents the formation of oxides). One of the ways in which sodium hydrogen sulfate is manufactured is by reacting sodium dichromate, Na2Cr2O7, with sulfuric acid. This process also forms water and chromium(VI) oxide, CrO3. Write a balanced equation for this reaction. (You do not need to include states.) How many kilograms of sodium dichromate, Na2Cr2O7, are necessary to produce 130.4 kg of sodium hydrogen sulfate?
