When you drink a liquid, how does it get out of your stomach without acid coming out aswell? How are they seperated?

They are not separated. The food/liquid that you eat acts as a buffer, and the mixture is passed along to the small intestine through the pyloric sphincter. The small intestine has both bile produced by the liver and concentrated/stored in the gallbladder and bicarbonate produced by the pancreas added to the mixture from the stomach. These are both bases, and serve to help neutralize the acid and to provide the proper environment for your intestinal enzymes. The stomach is continuously (unless it is suppressed by a physiological action) making more acid from specialized cells.
