Gastritis is often caused by the gastric mucosa failing to produce the right amounts of gastric juices, the MUSC Digestive Disease Center reports. Sometimes an endoscopic exam reveals the stomach's mucosal layer to be inflamed and swollen. The exam may even show bleeding areas in the stomach.
Daltonâs atomic theory stated that: All the matter is made of atoms which are tiny particles and indivisible. All the given atom of the element is identical in mass, size, shape, and in other properties. All different elements have different types of atoms and also different in their mass, size, shape, and in other properties.
Daltonâs atomic theory also explains the law of constant composition: if all the atoms of an element are alike in mass and if atoms unite in fixed numerical ratios, the percent composition of a compound must have a unique value without regards to the sample analyzed. The atomic theory led to the creation of the law of multiple proportions.
