- A 60.0 g of CaC2 reacts with water to produce C2H2 and 81.2 g of Ca(OH)2. The reaction between these two substances are chemically written as: _______ CaC2 + ______ H2O → _____ C2H2 + _______ Ca(OH)2 Balance the chemical equation. Calculate the molar mass of CaC2 and Ca(OH)2? What is the theoretical yield of Ca(OH)2? What is the percent yield of this reaction if the actual yield of Ca(OH)2 exceeds 2.1 g ?arrow_forwardMgO reacts with water to form Mg(OH)2. If 5.00 g MgO is combined with 100.0 g H2O in a coffee cup calorimeter, the temperature of the resulting solution increases from 22.3 °C to 32.9 °C.

- QUESTION 7 (Start on a new page.) The airbags in motor vehicles contain the compound sodium azide (NaNs). When a car crashes into an object, the compound decomposes and the nitrogen inflates the airbag. The balanced equation for the reaction is as follows: NaN(s) → 2Na(s) + 3N2(g) In one such decomposition, 2,53 x 10° molecules of nitrogen are generated. Calculate the: 7.1 Number of moles of NaN(s) that decomposed 7.2 Volume of N2(g) produced Assume that the reaction occurs at standard pressure. QUESTION 8 (Start on a new page.) Aluminium sulphate is used as a coagulant in water purification. It reacts with sodium hydroxide to form aluminium hydroxide which drags the impurities as it settles. The balanced equation for the reaction is: Al2(SO4)3(aq) + 6NaOH(aq) → 2Al(OH)3(s) + 3Na2SO4(aq) A chemist at a water purification plant adds 700 g of Al2(SO4)3 to a sample of water. 8.1 Calculate the maximum mass of Al(OH)3 that can be produced from this mass of Al2(SO4)3.

O2- AP+ Mg2+ o Vacancy A substitutional solid solution of Al½O3 in MgO is not as simple as the case of NiO in MgO. The requirement of charge neutrality in the overall compound permits only two Al+ ions to fill every three Mg²+ vacant sites, leaving one Mg²+ vacancy.
