CaC2(s) + 2H2O (g) --> Ca(OH)2 (s) + C2H2 (g) The complete reaction of 57.4 g of CaC2 requires consumption of _____g of H2O ? Normally, the balanced chemical equation following by the particular stoichiometric coefficients are essentially be desired for the estimation of unknown moles and mass. 0. This program was created with a lot of help from: The book "Parsing Techniques - A Practical Guide" (IMHO, one of the best computer science books ever written. Convert grams CaCl2.2H2O to moles or moles CaCl2.2H2O to grams. carbon (C) has a weight of 12.011 g/moles. When deployed, automobile air bags rapidly inflate as sodium azide (NaN3) decomposes into its component elements: 2NaN3 > 2Na +3N2. Question1: Molar mass H2O = 18g/mol. Bobby. 1 Answer. 2.72/2 = 1.36 mol C2H2 will react with 2.72 mol H2O. Which statement defines the enthalpy of solution? Chemical reaction. {\rm{Number}}\;{\rm{of}}\;{\rm{moles}} &= \dfrac{{{\rm{34}}{\rm{.84}}\;{\rm{g}}}}{{{\rm{64}}{\rm{.099}}\;{\rm{g/mol}}}}\\ However, calcium carbide production requires extremely high temperatures (~2000°C) and is hence not very feasible. The answer will appear below; Always use the upper case for the first character in the element name and the lower case for the second character. Lv 5. Nila. now for calculation: water mol. 32g CaC2 are consumed in this reaction how many mol of H2O are needed & of each product.
