A)4.5 B)9.0 C)18 D) 4.8x10EXP2 E) 4.8x10EXP-2 Chemistry. You don't have that much! 2H20 (l) + CaC2 (s) → Ca(OH)2 (s) + C2H2 (g) water and calcium carbide react to form calcium hydroxide and acetylene 4.5B. CaC2(s)+2H2O(l)→Ca(OH)2(aq)+C2H2(g) Part B When solid potassium chlorate is heated, it decomposes to form solid potassium chloride and oxygen gas. B) ethanoic acid. If the ΔH for: CaC2(s) + 2H2O(l) = Ca(OH)2(s) + C2H2(g) is -127 kJ, then what is the enthalpy of formation for calcium . When 1 mole of CaC2 reacts it gives H=-128.0kJ. (The rate of the reaction may vary). 9.0C. When calcium carbide reacts with heavy water, deuterated acetylene (C 2 D 2 ) is formed. When calcium carbide (CaC2) comes into contact with water, it produces ethyne (C2H2) according to this equation: CaC2(s) + 2H2O(l) → C2H2(g) + Ca(OH)2(s). 4.8 x 102E. That means that in the end there is an amount of CaC2 that hasn't reacted. 18D. C) ethane. Calcium carbide (CaC2) reacts with water to form acetylene (C2H2) gas and calcium hydroxide (Ca(OH)2). 26 Question When CaC\(_2\) reacts with water, the organic product forms is Options. 2 moles of water require 1 mole of CaC2: so actually 55.5 moles of water react with 27.75 moles of CaC2 which leaves 26.93 moles unreacted. D) ethyne A) ethanol. Question 9 Calcium carbide (CaC2) reacts with water to produce acetylene (C2H2) as shown in the reaction below: CaC2 (s) + 2 H20 (g) - Ca(OH)2 (s) + C2H2 (g) How many grams of H20 (molar mass: 18 g/mol) are required to completely react with 52.4 g of CaC2 (64.10 g/mol). C a C 2 + 2 D 2 O → C 2 D 2 + C a ( O D ) 2 Answer verified by Toppr CaC2 + 2 D2O → C2D2 + Ca(OD)2 D2O is not very different from H2O in most of its chemical properties and it reacts very much similar to H2O with CaC2. Get an answer to your question If 4.55 mol of calcium carbide (CaC2) reacts with an excess of water, how many moles of acetylene (C2H2), a gas used in welding, will be produced? When 27.75 moles react, they give H=27.75*(-128)=-3552kJ. The … Suppose this reaction takes place in a sealed container in which the gas occupies a volume of 1.50 liters. Problem: Calcium carbide (CaC2) reacts with water to produce acetylene (C2H2): CaC2 (s) + 2 H2O (g) → Ca(OH)2 (s) + C2H2 (g)Production of 13 g of C2H2 requires consumption of _____ g of H2O.A. Problem: Calcium carbide (CaC2) reacts with water to produce acetylene (C 2H2) according to the equationCaC2(s) + H2O(l) → Ca(OH)(s) + C2H2(g)A certain mass of CaC2 reacts completely with water to give 64.5 L of C 2H2 at 50.0°C and P = 1.00 atm. Calcium Carbide(CaC2) reacts with water to produce Acetylene(C2H2): CaC2(s)+2h2O(g) - - - -> Ca(OH)2(s)+C2H2(g) production of 13g of C2H2 requieres compsumption of _____g of H2O." Solid calcium carbide, CaC2, reacts with water to form an aqueous solution of calcium hydroxide and acetylene gas, C2H2.
