There are many different types of antacids, each with a slightly different mechanism of action. All of these neutralize stomach acid (HCl) through some reaction. The Example below uses calcium carbonate, which is used in the popular antacid "Tums".
2 HCl + CaCO3 --> CaCl2 + H2O + CO2
A way to envision this reaction is that the hydrochloric acid "eats away" at the calcium carbonate, forming CaCl2, an ionic species, and H2CO3 (carbonic acid) which is not stable at standard conditions. This rapidly decays to H2O and CO2 at normal pressures (like when you open a can of soda), which is why these are written on the products side of the reaction.

What is it called when fresh water meets seawater?
When fresh water meets seawater, it is called a "brackish water" environment. This occurs in estuaries or coastal wetlands where rivers flow into the ocean.
Fertilization of the ovum occurs where?
Fertilization of the ovum typically occurs in the fallopian tube, not long after ovulation. The sperm meets the egg in the fallopian tube, and fertilization usually takes place there before the fertilized egg then travels to the uterus for implantation.
What is the term for the place where a tide meets a current river?
The term for the place where a tide meets a river current is called the "tidal bore." This phenomenon occurs when the rising tide enters a river channel, causing the water to flow upstream against the current.
When does epithelium of esophagus change to squamous?
I believe that the esophagus does not change to squamous as it already contains stratified squamous epithelium (keratinization depends on species and diet) post- soft palate.

What is the cardioesophageal sphincter?
The oesophagus is the first part of the alimentary tract after the oropharynx. The cardio-oesophageal junction is the point where the oesophagus meets the stomach (at it's cardiac end - meaning the part of the stomach closer to the heart), where there is a circumferential thickening of the muscles in the wall of the gastrointestinal tract (tube). This extra thickening in the muscle layer is called the cardio-oesophageal sphincter. When food swallowed reaches this part, the sphincter dilates (expands/opens) to allow food to pass through from the oesophagus to the stomach. Once the food passes, the sphincter contracts (narrows/closes down) to prevent the contents of the stomach from returning back to the oesophagus. Regurgitation of stomach contents and resultant vomiting occurs when the functioning of this sphincter becomes defective.
What does a perch's pyloric caeca do?
The Pyloric Caeca is a finger-like out-pocketing of the intestine where it meets the end of the stomach (pylorus). Also spelled cecum (ceca). Serves to aid digestion. It is basically where digestion occurs, as it aids the stomach in digestion.
Where does ocean current occurs in the world?
it occurs when 2 or more ocean meets
Which event occurs first in Success Story?
The narrator meets Richards Richards meets the narrator.
What occurs when a ray of light meets an obstacle such as a fine wire?
Diffraction
What is the region of the stomach where the lower esophageal sphincter meets the stomach?
The cardia of the stomach is the region just below the Z-line at the LES. See the image link below for an image of the Z-line, LES and cardia of the stomach.
What is Juliet's reaction when she meets romeo for the first time?
She flirts with him. Although he starts the flirting.
What you get when acid meets metal?
Remember the general acid reactions. Acid + metal = salt + hydrogen Acid + Alkali = Salt + Water Acid + Base = Salt + water Acid + Carbonate = Salt +Water + Carbon dioxide. NB An Alkali is a soluble Base.
Occurs when a cool air mass meets and replaces a warm air mass?
A cold front.
Constructive interference occurs when the crest of one wave meets up with the trough of a second wave true or false?
False. Constructive interference occurs when the crest of one wave meets up with the crest of a second wave, or when the trough of one wave meets up with the trough of a second wave. This results in a wave with greater amplitude.
What occurs between Juliet and romeo at the masque?
They fall in love at first sight
What happens when iodine meets starch?
When iodine meets starch, a bluish-black coloration results. This reaction is used in a common test to detect the presence of starch in a substance.
What happens when you add an alkali to an alkali?
A chemical reaction. Acid + alkali = salt + water eg H2SO4 + 2NaOH = Na2SO4 + 2H2O Sulfuric acid + Sodium Hydroxide = Sodium Sulfate + water Whan as acid meets an alkali they create a chemical reaction. If there is an acid and you add a weak alkali you should bring it down to neutral.
