The deltaH for the decomposition of 1 mole of Al2O3 is half of 351.4 kJ since the chemical equation shows 2 moles of Al2O3. Convert 12.50g Al2O3 to moles by dividing it by the molar mass of Al2O3. Multiply your answer by 351.4kJ to get the enthalpy of decomposition of 12.50g A...
CH3CH2CH2CH2OH + NaBr --> CH3CH2CH2CH2Br + NaOH. NaOH would react with H2SO4 to form Na2SO4 which may precipitate in a mixture of organic solvents.
Para (p-), meta (m-), and ortho (o-) are only used for derivatives of benzene. Your acid was probably 4-methylcyclohexanoic acid.
Start with: CH3CH2CH2-C-OCH(CH3)2 To the middle -C-, attach an -OH (up) and an -H (down). See also: http://en.wikipedia.org/wiki/Hemiacetal
1. Errors related to the measurement of volume of acetic acid (what volumetric glassware was used and how it was used). 2. Errors related to using and reading the buret with the NaOH solution. 3. Errors related to reaching the endpoint. Color, etc. 4. Possible error in the val...
The unpaired electron in the ethyl radical can be more easily delocalized by two carbon atoms, and through the increase in the number of resonance forms in a two-carbon chain.
nf would be the square root of some positive value, but your (A) and (B) look the same. Did you copy these alternate answers correctly?
1/lambda = R/ni^2R/nf^2 y = mx + b (standard form) of a linear equation) x = (y-b)/m Let, y = 1/lambda m = -R x = 1/nf^2 b = R/ni^2 1/nf^2 = [(1/lamda)-(R/ni^2)]/(-R) Solve for nf
Surface tension is the result of intermolecular forces. Viscosity is also the result of intermolecular forces plus additional factors such as entanglement of long molecules. What intermolecular forces are involved from C6H14 to C9H20? How would the increasing length plus incr...
