Solution for Using the equations Ca (s) + ½ O2 (g) → CaO (s) AH° = -635 kJ/mol CaO (s) + H2O (1) → Ca(OH)2 (s) AH° = -64 kJ/m 2 H2 (g) + O2 (g) → 2 H2O (I) AH°… Replace immutable groups in compounds to avoid ambiguity. Become a Patron! When Al3+ and Br- combine, the formula of the product is Al3Br. For example, C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but XC2H5 + O2 = XOH + CO2 + H2O will. Сoding to search: CaCl2 + 2 H2O cnd [ temp ] = CaOH2 + 2 HCl. How To Balance Equations. Assuming that the specific heat of the solution is 4.18 J/(g⋅∘C) and that the calorimeter itself absorbs a negligible amount of heat, calculate ΔH in kilojoules for the reaction CaO(s)+H2O(l)→Ca(OH)2(aq) When 1.045 g of CaO . You can use parenthesis or brackets []. Add / Edited: 03.03.2015 / Evaluation of information: 5.0 out of 5 / number of votes: 1. Ca2O + H2O -->2Ca(OH)2. Expert Answer . Show transcribed image text. Its usage varies from about 30 to 50 kilograms (65–110 lb) per ton of steel. How To Balance Equations. • The major use of quicklime is in the basic oxygen steelmaking (BOS) process. For instance equation C6H5C2H5 + O2 = C6H5OH + CO2 + H2O will not be balanced, but PhC2H5 + O2 = PhOH + CO2 + H2O will; Compound states [like (s) (aq) or (g)] are not required. Read our article on how to … All gases are assumed to be at STP. You can use parenthesis or brackets []. Calcium oxide reacts with water in a combination reaction to produce calcium hydroxide: CaO (s) + H2O (l) → Ca (OH) 2 (s) In a particular experiment, a 5.50-g sample of CaO is reacted with excess water and 6.77 g of Ca (OH) 2 is recovered. False. A four fixed-bed reactor system was used to investigate the effects of cerium addition and calcination conditions of calcium looping on simultaneous CO2 capture and thermochemical heat storage capacity of the composite in the coupled process. When barium and chlorine combine, the formula of the product is BaCl3. Limiting reagent can be computed for a balanced equation by entering the number of moles or weight for all reagents.
