In a constant-pressure calorimeter, 60.0 mL of 0.320 M Ba(OH)2 was added to 60.0 mL of 0.640 M HCl.
The reaction caused the temperature of the solution to rise from 22.06 C to 26.42 C. If the solution has the same density and specific heat as water, what is deltaH for this reaction (per mole of H2O produced)?
Assume that the total volume is the sum of the individual volumes
how many liters of H2 would be formed at 628 mm Hg and 14 degrees celcius if 22.5g of zinc was allowed to react
Treatment of the bicyclic chloride A with lithium in tetrahydrofuran (THF) gave the monocyclic product B, C9H9Li. In deuterated THF, B exhibited a single proton NMR signal at 6.72 ppm
It requires 251 J to melt 2.22 g of sodium metal at its normal melting point of 98°C. Calculate the molar heat of fusion of sodium.
A 515 g piece of copper tubing is heated to 95.0°C and placed in an insulated vessel containing 57.0 g of water at 30.0°C.
Calculate the molarity of an aqueous NaOH solution if 30.10ml of .500M H2SO4 is required to reach the end point when titrated against 10.00mL of NaOH solution.
explain what ( if anything) is wrong with the following student's statement: " our solution is red, so we should set the spectrophotometer to the red light range
A critical reaction in the production of energy to do work or drive chemical reactions in biological systems is the hydrolysis of adenosine triphosphate, ATP, to adenosine diphosphate, ADP, as described by
Calculate the amounts of C 7 H 8 , C 7 H 16 , and H 2 in the output stream express your answer (in mol s -1 ).
In an electrolysis cell similar to the one employed in this experiment, a student observed that his unknown metal anode lost 0.238 g while a total volume of 84.90 mL of H2 was being produced
What is the buffer component ratio, ([CH3CH2COO-]/[CH3CH2COOH]) of a propanoate buffer that has a pH of 4.49. Ka of CH3CH2COOH is 1.3 x 10-5.
A muon is an elementary particle with a negative charge equal to the charge of an electron and a mass approximately 200 times that of the mass of an electron.
A beaker with 1.70×102 mL of an acetic acid buffer with a pH of 5.000 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 6.20 mL of a 0.490 it M HCl solution to the beaker. How much wi..
