Would this reaction be an example of saponification? phenyl-COOCH2CH3 + NaOH ----> phenyl-COONa + CH3CH2OH I ruled out Aldol condensation and enolization, and I don't think it's esterification, but it doesn't quite fit the description of saponification in the text or in my head
What is the mass percent of Ca in the alloy. The unbalanced equations are given below. (Hint: Let x = mass of Ca in the alloy in grams

what mass of calcium carbonate is required to react with 137.8 mL of a 0.6943 M sulfuric acid solution?
The bond dissociation energy of Br2(g) is 193 kJ/mol, and the electron affinity of bromine is -325 kJ/mol. The enthalpy of vaporization of Br2 (l) is 31 kJ/mol. The lattice energy of KBr is -682 kJ/mol. Calculate the overall enthalpy change for th..
A sample of gasoline contains various hydrocarbons, which comprise atoms of carbon, hydrogen, and oxygen. The hydrocarbons mix together uniformly to form gasoline.
Calculate the work, w, if the gas expands against a constant external pressure of 1.00 atm to a final volume of 25.0 L.
The pressure increases from 1.10 atm to 3.06 atm, and the volume of the sample changes from 2.67 L to 4.57 L. To what temperature, in oC, was the methane heated?
