what is the total volume of gases produced by the combustiooon of 500g of butane. assume 1 atm, temp 28 degrees C and that water is produced as a gas. c4h10 + 6.5o2 = 4co2 + 5h2o
A solution is prepared by mixing 250 mL of 1.00 M CH3COOH with 500 mL of 1.00 M NaCH3COO.
The dipole moment (h-BR) of (a polar covalent molecule) is 0.82 (debye), and its percent ionic character is 12.1. Estimate the bond length of the bond in picometers.
aluminum sulfate and sodium phosphate Express your answer as a chemical equation. Identify all of the phases in your answer.
At 700 K the equilibrium constant for the reaction is Kp = 0.76. CCl4(g)-> C(s) + 2 Cl2(g) A flask is charged with 2.00 atm of CCl4, which then reaches equilibrium at 700 K. (a) What fraction of the CCl4 is converted into C and Cl2?
Using active extraction (changing the polarity) and a gravity filtration to remove a component, describe how you would obtain pure naphthoic acid from this mixture.
NMR of D exhibits resonance at -4 ppm. - On heating D, a flammable gas and A are formed. - Reaction of C with CH3I affords white solid E whose proton NMR shows a single resonance around 0.2 ppm. Identify A-E.
