Calculate the amount of heat transferred when 28.0 grams of CH3OH(g) is decomposed by this reaction at constant pressure.
Which of the following would you expect to be a molecule and which would you expect to be part of an ionic solid? Drag the appropriate compounds to their respective bins. CO, NO, LiCl, HBr, BaS, RbCl, SrO, LiBr
Calculate the heat evolved when 306 g of white phosphorus (P4) burns in air according to the equation below.
Suppose that 0.35 mol of hydrogen gas and 0.35 mol of clorine gas are placed in a 1L reaction vessel at a certain temperature, and the following reaction comes to equilibrium
The solubility of a certain compound in ice-cold water is .19g in 100mL. its solubility in hot water is 3.35g in 100mL.
A 0.75-L bottle is cleaned, dried, and closed in a room where the air is 24°C and 50.% relative humidity (that is, the water vapor in the air is 0.5 of the equilibrium vapor
A 0.15 M solution of chloroacetic acid has a pH of 1.86 What is the value of Ka for this acid
Uric acid dissociates with a pKa of 5.80, and can be treated as a simple monoprotic acid in this pH range. Its solubility in urine depends on the relative amount of protonated and unprotonated forms
0.500 g of CuI was used to couple 2.0 mL of 1-hexyne what is the mole % of the CuI catalyst that was used? This is as Cu-catalyzed diazo coupling reaction that coupled ethyl diazoacetate with 1-hexyne.
Calculate the pH at the equivalence point in titrating 0.100 M solutions of each of the following with 7.0X10^-2 M NaOH.
Therefore, a more systematic manner of indicating stereochemistry in these systems has been developed that uses the E and Z nomenclature system.
A 0.100M (as prepared) solution of dichloroacetic acid has an observed [H30+]= .043 M. What are the equilibrium concentrations and the value of the equilibrium constant for the reaction shown?
Traces of toxic, man-made hexachlorohexanes in North Sea sediments were extracted by a known process and by a new procedure, and measured by chromatography.
