The left ventricular ejection fraction (LVEF) test rate is increasingly used as a quality of care indicator for pa-. tients with heart failure. Our study produced benchmark LVEF test rates in a Medicare fee-for-service.
Toluene is a very good solvent because, unlike water, it can dissolve many organic compounds. In many commercial products, toluene is used as a solvent that is present in paint thinners, nail polish remover, glues, and correction fluid. Toluene has many uses in different industries.
Hydrocarbons are non-polar. Water is polar. So from âlike dissolves likeâ you wouldnât expect any of these three to be very soluble in water. In fact, unsaturated and aromatic hydrocarbons are slightly soluble in water-the solubility of toluene in water is ~500mg/L â not very much. Cyclohexene is even less than that.Cyclohexane is completely insoluble in water.ater is polar. So from âlike dissolves likeâ you wouldnât expect any of these three to be very soluble in water.
