Draw a Lewis structure for acyl chloride R-C(=O)-Cl and state its 3D-structure around the central atom (C). R is an acyl substituent.
Sims Inc. earned $1.00 per share in 2000. Five years later, in 2005, it earned $2.00. What was the growth rate in Sims' earnings per share (EPS) over the 5-year period?
The reaction of fluorine of 7.6 grams with excess chlorine(Cl) produced 3.3 grams of ClF3. Determine the percent yield of ClF 3 was obtained??
Calculate the difference in pressure between methane and an ideal gas under these conditions. The van der Waals constants for methane
Why Do I Require More CaCO3 to Raise pH than Predicted? If you can remember back to a discussion and inquiry we exchanged last week concerning the use of sodium carbonate vs. calcium carbonate
Calculate the pH of a buffer solution made by adding 10.0g of anhydrous sodium acetate (NaC2H3O2) to 100 ml of 0.100M acetic acid.
A is allowed to come in contact with substance B. B has a mass of 46.28 grams and its initial temperature is 86.5oC. These two substances reach thermal equilibrium at a temperature of 64.2oC. If the specific heat capacity of substance B is 1.17 J/..
KEtones also undergo the aldo condensation, although a succesful reaction often requires "enhanced" conditions, since the addition involves an unfavorable equilibrium constant.
What was the composition of the mixture of Mg and Zn expressed as percent by mass? If the volume of acid used was 100 mL, what were the final molar concentrations of MgSO4 and ZnSO4?
A suitable storage place must be geologically stable long enough for the activity of plutonium-239 to decrease to 0.1% of its original value.
Draw the Lewis structure of the major resonance form of the thiosulfate ion, S2O3 2-. Include all lone pairs of electrons. Include formal charges on atoms with charges.
