There are several aromatic compounds with the formula C8H9Cl. Draw those that have a trisubstituted ring where the methyl groups are oriented meta.
Calcium hydride, CaH2, reacts with water to form hydrogen gas. CaH2(s) + 2 H2O(l) → Ca(OH)2(aq) + 2 H2(g)
A 21.10 g sample of liquid ethanol is initially at -36.90 oC. If the sample is heated at constant pressure (P = 1 atm.), how much kJ of energy are needed to raise the temperature of the sample to 100.60 oC.
An alcohol is 12.61 percent Hydrogen, 37.47 percent Carbon, and 49.92 percent Oxygen by mass. Determine the empirical formula of the alcohol.
