acetic acid has one carbon- oxygen bond that is 1.36 A nd another 1.23 A however sodium acetate has two equal carbon- oxygen bonds each 1.27A long Explain
what would the final common temp be assuming no heat loss? Use Cp for ethanol = 60.0 J K -1 mol -1 and Cp for Copper = 0.380 J K -1 g -1.
What is the molarity (M) of the concentrated HClO4 solution?
What is the density of a block of marble that occupies 350 cm3 and has a mass of 660 g?Answer in units of g/cm
However, if you treat formaldehyde (CH2O) with potassium cyanide in water, you will not produce the cyanohydrin. You may even produce C3H6O3 (i.e., dihydroxyacetone and glyceraldehyde). Explain this either in words or reactions.
Calibration standards.Transfer 1.00, 5.00, 10.00, 15.00 and 20.00 mL aliquots of 10ppm F- solution to 100 mL flasks. Add 50 mL of TISAB containing CDTA to each
How many liters of H2 at 23.0C and 733mm Hg are released when 1.98g of Na reacts with unlimited water?
What volume of 0.150M HClO4 solution is needed to neutralize 45.00mL of 8.80×10^-2 M NaOH?
Which starting material is the limiting reagent in this procedure? Which reagent is used in excess? How great is the molar excess (how many times greater)?
what will the pH be after mixing the 100 ml of HCl solution and the solid NaOH together? Assume the addition of NaOH does not change the volume. (Molar Mass NaOH= 40.00 g/mole : Molar Mass HCl = 36.46 g/mole
Calculate the delta H and delta S if the temperature of 1.75 moles of Hg(l) is increased from 0.00C to 75.0C at 1 bar. Over this temperatur range, Cp,m(J K^-1 mol^-1)=30.093-4.944 x 10^-3T/K.
an unknown gas sample is collected in a 255 ml countainer at 25c and 755 mm hg. how many moles of gas are present?
Alpha terpene, C10H16, is a pleasant-smelling hydrocarbon that has been isolated from oil of marjoram. On hydrogenation over a palladium catalyst, alpha terpene reacts with two molar equivalents of H2 to yield a hydrocarbon C10H20
