A(n) ____________ is made of two or more substances that are ____________ combined.

Whether or not a substance is classified as an acid has to do with what happens when the substance dissolves in water. If the substance releases hydrogen ions, it is considered acid. The number of hydrogen ions that are released is what determines whether a substance is more acid or less. Another way to identify an acid is by tasting it. Spirits, such as gin, rum, vodka, and whiskey, are made through distillation. This is an industrial process that makes drinks with higher alcohol concentrations (40% or more). Alcohol for other purposes. There are two other main types of alcohol, both of which are unsafe to drink: isopropyl alcohol (known as rubbing alcohol) crashes combined. In fact, between 1999 and 2015, more than 560,000 people in this country died due to drug overdoses – this is a death toll larger than the entire population of Atlanta.
