Nitric acid has the chemical formula HNO3, and Calcium Hydroxide has the chemical formula Ca(OH)2. When an acid and a base react with each other, the products that are formed is a salt (an ionic compound that is formed from a reaction between an acid and a base) and water.
2019-5-4 · Barium chloride is the inorganic compound with the formula BaCl2. It is one of the most common water-soluble salts of barium. Like most other barium salts, it is white, toxic, and imparts a yellow-green coloration to a flame. It is also hygroscopic, converting first to the dihydrate BaCl2(H2O)2. It has limited use in the laboratory and industry.
The net ionic equation is a chemical equation for a reaction which lists only those species participating in the reaction. The net ionic equation is commonly used in acid-base neutralization reactions, double displacement reactions, and redox reactions. In other words, the net ionic equation applies to reactions that are strong electrolytes in
The Half-Reaction Method of Balancing Redox Equations . A powerful technique for balancing oxidation-reduction equations involves dividing these reactions into separate oxidation and reduction half-reactions. We then balance the half-reactions, one at a time, and coine them so that electrons are neither created nor destroyed in the reaction.

Chemical equations reflect this conservation. It is why chemical equations must be balanced. Atoms have mass, and the nuers of each kind of atom on each side of the equation must be the same. Coefficients, the nuers to the left of the formulas, are used to balance equations.
Calcium Chloride is a crystalline, white substance, soluble in water, Calcium Chloride is the chloride salt of calcium, a bivalent metallic element with many crucial biological roles. Calcium is a major constituent of the skeleton but plays many roles as an intracellular and plasma ion as well. In medicine, calcium chloride is also used as a 10% solution in injection, for calcium replenishment.
