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...
Organic chemistry
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.

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^2–R/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...
