A piston-cylinder device contains 0.8 kg of an ideal gas. Now, the gas is cooled at constant pressure until its temperature decreases by 10°C. If 16.6 kJ of compression work is done during this process, determine the gas constant and the molar mass of the gas. Also, determine the constant volume and constant-pressure specific heats of the gas if its specific heat ratio is 1.667.
A solution of potassium cyanide, KCN, instead of conc NH3 is added to copper(II) sulfate pentahydrate ([Cu(H2O4)]SO4.H20). Wrtie the formula of the expected complex ion.
Diethyl ether have a vapor pressure of 401 mmHg torr at 18 0C and its molar heat of evaporation is 26.0 kJ/mol explain what is its vapor pressure at 32.00C ( R = 8.314J/K.mol)
The heat of fusion of acetic acid, the principal organic component of vinegar, is 45.9 cal/g.How much heat (in kilocalories) is required to melt 3.65 mol of solid acetic acid
a mixture of mgco3 and caco3 was dissolved in hcl 1.64g of a mixture of calcium carbonate and magnesium carbonate was
A gas is confined to a container with a massless piston at the top. (Figure 2) A massless wire is attached to the piston. When an external pressure of 2.00 is applied to the wire, the gas compresses from 5.90 to 2.95
The pKa values for some weak acids are given Which is the strongest acid of the group. A. pKa=2.5 B. pKa=7 C. pKa=9.2 D. pKa values have nothing to do with acid strength
sodium hydrogen carbonate how do I figure out how many moles of carbon dioxide are in the balloon? The circumference of the balloon is 5.89 cm.
Given a four-carbon chain with two methyl groups and an NH2 group on the fourth carbon and a C=O double bond and an H on the first carbon. It asks me to draw the product of the reaction of this molecule with H3O+ (cat.) and Delta toluene.
Enter the correct expression for the reaction rate corresponding to each of the following mechanisms:
Calculate the average translational kinetic energy (sometimes just called average kinetic energy) for one mole of gas at 385 K.
State structures for the a variety of aldol condensation products you expect from the aldol self-condensation of 2-butanone,CH3C(=O)CH2CH3.
it is noted that at some conditions consists atmospheric pressure 1.0atm and temperature 26.6c a container is
