Alka Seltzer Research Paper
Alka-seltzer is a medicine. Dropping a tablet into a water, you could watch it dissolve into a medicine and the antacid ingredients go to work instally, it will bubble that means it's working, it makes noise also. When you mix effervescent tablets with water, a chemical reaction takes place between the citric acid and sodium bicarbonate contained in the tablet + water.
Gas pressure- Liquids and gases flow. Not like liquids gases have no volume. This means gases can fit in a big space or a small space. Their molecules move closer together or farther apart. Gases spread as far as they can to fill any container. Gas could be moved into a small space. The same amount of gas could also fill up an entire room. This makes gases different from liquids.
Chemical Change-A chemical reaction happens when matter mixes with other matter and causes change. During a reaction, two or elements or compounds form a new product.The elements or compounds that change in a chemical reaction are called reactants Compounds the chemical reactions create are called products.
