What is the largest alkane (number of carbons) that can be named not exceeding "decane" as a parent? Where is the primary How many What family. I.e. what Where and what carbons? Is the primary functional group?
Are the substituents? Functional group? Torsional strain (excess energy in the non-staggered conformations) is due to increased CH bonding electron repulsion. The "extra" energy of some conformations due to less than optimal molecular geometry, can be accounted by torsional and steric strain. (Other compounds may also have angle strain.) What is the minimum energy difference between the "straight" and once "bent" chain?
how much heat is transferred when 400 grams of mercury (Hg) is vaporized? specific heat (c) = 0.14J/g C, heat of fusion = 2.29 kJ/mol, heat of vaporization = 59.1 kJ/mol.
Magnesium hydroxide is only very slightly soluble in water. The reaction by which it goes into solution is: Mg(OH)_2 (s) Mg^2+ (aq) +2 OH- (aq)
Draw a free body diagram of a container of water that you are holding, you walk with the container at a constant speed and then stop abruptly.
Calculate the pH of a buffer solution that contains 0.25 M benzoic acid (C6H5CO2H) and 0.15 M sodium benzoate (C6H5COONa). [Ka = 6.5 ? 10-5 for benzoic acid]
This reaction is sometimes used to inflate life rafts, weather balloons, and the like, where a simple, compact means of generating H2 is desired. How many grams of CaH2 are needed to generate 143L of H2 gas if the pressure of H2 is 823torr at 21de..
What mass of the hydrate could be recovered from the solution? When separated from a H 2 O solution, copper sulphate forms a hydrate with 5
Bromocresol green, Ka = 2.0x10^-5, is yellow in its protonated form (HX) and blue in its ionized form (X^-). At what pH will bromocresol green be a perfect green color
Determine the error in the molar mass of Mg(ClO4)2. If 0.982(+/- 0.002)g is dissolved in a 250 mL (+/-0.08 mL) volumetric flask and water added to the mark, what is the concentration and error in the concentration of ClO4-?
The Solubility of Silver Bromide at 100 Celsius degrees is 0.00037 grams for 100 grams of water. Calculate Ksp for Silver Bromide at this Temperature.
Classify the following pair of compounds as the same compound, enantiomers, diastereomers, constitutional isomers, or not isomeric. Also, select the correct IUPAC name
Express your answer with the appropriate units. Indicate the multiplication of units explicitly either with a multiplication dot (asterisk) or a dash
A thermos container has 0.075 kilograms of distilled water at a temperature of 27 degrees Celcius. A 0.0076 kilogram sample of solid ammonium nitrate is dissolved in the water in the Thermos container and the temperature is measured to be 22.4 deg..
