51. Predict which solute is more soluble in the given solvent. (I) 1,4-butanediol (HOCH2CH2CH2CH2OH) or butanol (CH3CH2CH2CH2OH) in water (II) Chloroform (CHCl3) or carbon tetrachloride (CCl4) in water I II produced by the reaction of 60.0 g of aluminum oxide with enough amount of carbon according to the following chemical reaction? Al2O3+ 3C 2Al + 3CO 56. The combustion of propane, C3H8, produces CO2and H2O: C3H8(g) + 5O2(g) 3CO2(g) + 4H2O (g) A. 1,4-butanediol chloroform B. 1,4-butanediol carbon tetrachlorideC. butanol chloroform D. butanol carbon tetrachloride
