Transesterification occurs when an alcohol (in excess) reacts with an ester. Draw the skeletal structure of the ester formed when ethyl propanoate (propanoate = propionate) reacts with 1-propanol.
A heater burns propane (C3H8) using 30.0% excess air. Combustion is complete. The flue gas leaves at a pressure of 100 kPa and a temperature of 260°C. a. Calculate the flue gas composition
the ground water in pherric new mexico contains 1.80 mgl of iron as fe3. what ph is required to precipitate all but
Starting with a sample of (R)-2,3-dimethylhexan-3-ol, provide the best synthesis of (R)-3-chloro-2,3-dimethylhexane

Formic acid, CH2O2, can be decomposed to produce hydrogen. The Lewis structure for formic acid, CH2O2, is show below. The atoms are labeled A, B, C, D, E.
how many grams of oxygen are collected in a reaction where 231 ml of oxygen gas is collected over water at a
Pure chlorobenzene boils at 404.86 K. (a) Construct the chlorobenzene-rich portion of the phase diagram from the data. (b) Estimate the temperature at which a solution whose mole fraction of 1-butanol is 0.300 begins to boil
That depicts that two hydrogen atoms bond with one oxygen atom to make the compound we call water. If water comprises most of our body mass explain simply why there is a greater amount of oxygen by mass in our bodies than hydrogen.
Following is an example of a triprotic acid with pK values closer than 3 units, and pK3 less than 10. You have a 20.0 mL solution of the triprotic acid, H3A, with a concentration of 0.128 M, and are titrating it with a 0.250 M solution of NaOH.
