Problem- Consider why it takes so much more heat energy to go from liquid to gas than to go from solid to liquid.
Solve the above problem in detail no word count
The complete conversion of 2-phenylacetic acid to ethyl-2-phenylacetate in this experiment is the result of. Ethanol being in excess relative to 2-phenylacetic acid
A 1.00 g sample of D2O and H2O are reacted with CL2 and HCL and DCL are produced. Then they are diluted with H2O giving a volume of 1.00L. Then 25 mL of the solution are reacted with excess AgNO3 and 0.3800g AgCl precipitate formed.
When the liberated hydrogen gas is collected over water at 29 degrees celsius and 752 torr, the volume is found to be 343 mL. The vapor pressure of water at 29 degrees celsius is 30.0 torr. What is the mass percentage of aluminum in this alloy?
Calculate the half life of N2O5 and B. how long does it take for the N2O5 concentration to drop one tenth of its original value. * I believe the half life is 10,000 seconds for part A. But I am having trouble with part B.
Bleach is a dilute solution of NaOCl in water. The density of bleach is 1.05g/ml. If the percent by mass of NaOCl is 6% what is the [NaOCl]
In which solution (acidic, basic, neutral water, or doesn't matter) is potassium bromide most soluble
The buffer has a concentration of 150 mMol ( 150 mM of KH2PO4 / 150 mM K2HPO4. The pKa of the drug ephedrine is 9.6. Will the drug have a negative, positive, or neutral?
The photochemical reaction of 2,4-dimethylpentane with molecular chlorine affords a mixture of monochlorinated alkyl halides. Draw teh structures of these products and predict the molar ratio when the reaction is run at 25C
Are we concerned with the amount of sample that we use in this experiment and list at least three pros and cons for using a small sample under 0.05g and a large sample over 2.0g
A laser utilized to read CDs emits red light of wavelength 700 nm. Explain how many photons does it emit each second if its power is (a) 0.10 W, (b) 1.0 W
Question- How many milliliters of 0.135 M HCl are needed to completely neutralize 49.0mL of 0.101 M Ba(OH)2 solution? I need help to find the correct solution.
