Given the following set of data for the determination of empirical formula of magnesium oxide: - Mass of empty crucible = 15.79 g - Mass of crucible + magnesium = 16.43 g - Mass of crucible + magnesium oxide = 16.79 g - Molar mass (g/mol): Mg = 24.4; 0 = 16.0 The molar ratio of Mg to O is 0.86 APIT OF ENGINEERING 0.79 1.27 1.17 0.95

10. Using the following reaction 2KCIO; -2KCI +302 If 10g of oxygen were produced, what mass of KCIO, (GFM = 122.6g/mol) was added? %3D Number unit

What is the name of this reaction

Acetylene (C,H,) gas is often used in welding torches because of the very high heat produced when it reacts with oxygen (O. gas, producing carbon dioxide gas and water vapor. Calculate the moles of acetylene needed to produce 1.50 mol of carbon dioxide. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits. olo &

Question 1 of 28 (1 point) Question Atempt 1of 1 Lindoe 10 11 12 13 There are two steps in the usual industrial preparaton of acrylic acid, the immediate precursor of several useful plastics. In the first step, calcium carbide and water react to form acetylene and calclum hydroxide: CaC,(s) + 2 H,O(g) → C,H,(0) + Ca(OH),(s) AH--414. k In the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6C,H,(9) + 3 CO,(9) + 4H,O(9) -SCH,CHCO,H(9) AH-132. kJ Calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. pund your answer to the nearest kJ.
