Problem- A sample of oxygen gas that contains onehalf of Avogadro's number of molecules has a mass of
Answer showing how to make each solution will get rated
It is important to know if a particular molecule is composed of elements with different electronegativities as well as the structure of the particular molecule to explain the physical properties of the molecule.
Estimate the mass of water that must evaporate from the skin to cool a body by 0.10, if the mass of the body is 91 and its heat capacity is 4.0 . (Assume that the heat transfer is 100 efficient.)
Draw the skeletal structure of meso-2,6-diaminopimelic acid (meso-2,6-diaminoheptanedioic acid). (Show one wedge bond, one dashed bond, and two sticks attached to the chiral carbon.
In lab a student titrates 50.00mL of an unknown monoprotic weak acid with 35.5mL of .9500M NaOH to reach the equivalence point of the titration. What volume of NaOH was delivered to reach the midpoint in this titration
Carbon-11 radioactively decays by positron emission with a half-life of 20.4 minutes. If a dosage of carbon-11 is administered to a patient for a PET scan, what percentage of carbon-11 will remain in the patient's system after 61.2 min
A student heated a 25.0g piece of a metal to a temp of 100.0C and placed it in 100.0g of water, initially at a temperature of 10.0C. Determine the final temperature of the system(aluminum and water)
Hypochlorous acid, HOCl, is a weak monoprotic acid. Using the information for this acid in Appendix F, calculate the pH (round to one decimal) and the percent ionization _2 _(round to two decimals) of a 0.1M solution of the acid at 250C.
Hydrogen has an electronegativity value between Boron and carbon and identical to phosphorous. With this in mind, rank the following bonds in order of decreasing polarity
Problem- a) Decide which is more stable: an aryldiazonium cation, or a cyclohexyldiazonium cation? Use resonance structures to justify your answer. b) Upon heating to temperatures above 50oC, aryldiazonium salts decompose and evolve nitrogen gas.
Using activity coeffient, calculate the pH of a 0.001M HCl solution. If you add a 0.010M solution of NaCl to this solution, will the pH increase, decrease or remain the same
A 54.14 g sample of a substance is initially at 28.6 C. After absorbing 2631 J of heat, the temperataure of the substance is 179.1 C. What is the specific heat (c) of the substance
The half-life of a particular element is 0.01256 years. How long would it take (in minutes) for the amount of to decrease to 89.56% of its initial amount, considering that radioactive decay is a first-order reaction.
