What is the maximum work that can be obtained from a 340 L tank of compressed air at 4350 PSI
To determine the empirical formula of ester, 1.02g of the ester was burnt completely in excess oxygen. The only products formed were 2.20g of carbon dioxide and .90g water vapor. Calculate the mass of oxygen in 1.02g of the compound.
The carbanion then reacts with a molecule of acetone to give the product. Assuming the steady state approximation is valid, determine the concentration of the carbanion and derive a rate equation for the formation of product
What is the volume percent of a solution prepared by dissolving 43 g of NaOH in enough water to make a final volume of 120 mL? Show your work.
rewrite the equation so heat of reaction (delta H) equals deltaHf for 4PCl3 (g) yields p4(s) + 6Cl2 (g) Values for delta HF in Kj/mol are:
The energy available is given in the question along with the percent efficiency. Use these values to determine the energy
The mass of an electron is 9.11 times 10^{-31}kg. If the de Broglie wavelength for an electron in a hydrogen atom is 3.31times 10^{-10} how fast is the electron moving relative to the speed of light? The speed of light is 3.0 times10^8 m/s.
