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?
A 14.0-g sample of CaCl2 is dissolved in 112 g of water, with both substances at 25.0°C. Calculate the final temperature of the solution assuming no heat lost to the surroundings and assuming the solution has a specific heat capacity of 4.18 J/°C ..
Explain the difference between equivalence point and end point... Explain how the pH at the equivalence point varies as the strength of the acid increases.
mixture(O,H) is ignited with a spark and it reacts to form (H2O)liquid water. determine the temperature of water.
How much heat is required to raise the temperature of 7.50 grams of water from 10 degrees celcius to 55 degrees celcius
For the reaction:2CH4(g) C2H2(g) + 3H2(g) 0.115 mole of CH4 was placed in a 1.00 L container. At equilibrium it was found that the [C2H2] = 0.035 M. What is the value of the equilibrium constant?
Take frequencies from sections on absorptions of selected functional groups in the text. If a functional group is not discussed specifically, use frequencies from Which compound will exhibit this absorption?
What is delta G for this reaction at 298 K when the partial pressures are PC2H6 0.15 atm, PH2 0.15 atm, and PCH4 0.75, What is the delta G in kJ/mol?
Rank from longest to shortest distance. To rank the items as equivalent, overlap them.
The titration curve of a 1.00 M unknown acid solution shows that the pH at the equivalence point is 9.16 and the pH halfway to the equivalence
