However, their major difference is that the skeletal muscle is controlled by the somatic nervous system, and the cardiac muscles are, by nature, involuntarily controlled. Besides their overall different locations within the body, these two muscles also have many differences in their cellular structures.he cellular characteristics of the cardiac and skeletal muscles differ greatly. The cardiac muscle cell is short when compared to the skeletal muscle cell, and the shape of the cardiac muscle cell can be referred to as âsemi-spindleâ, while the shape of a skeletal muscle cell is cylindrical.
The ammonium ion is a positively charged ion or cation and has the chemical formula, NH 4 +. Ammonium salts are commonly used in fertilizers. Examples of compounds containing the ammonium ion include, ammonium nitrate, NH 4 NO 3 and ammonium sulfate, (NH 4) 2 SO 4. All ammonium salts are soluble in water and dissociate or break down to produce aqueous ammonium ions. NH 4 NO 3 4 + (aq) + NO 3 - (aq) where aq = aqueous (surrounded by water) and s = solid. The ammonium ion is formed by the neutralization of the base ammonia, NH 3 with and acid. NH 3 + HNO 3 4 NO 3. NH 3 + H 2 SO 4 4) 2 SO 4. The ammonium ion has one co-ordinate covalent bond which involves the nitrogen atom donating two electrons in one of the N-H bonds.
Ammonium nitrate-sulfate (30-0-0 + 6.5S) is a dry nitrogen fertilizer relatively new to the United States. It is manufactured by reacting anhydrous ammonia with a mixture of nitric acid and sulfuric acid. The nitrogen content of the product will vary depending on the proportion of nitric to sulfuric acid.he reacted material is concentrated, prilled and coated to prevent caking. In ammonium nitrate, one-half of the nitrogen is in the nitrate form, and the other half is in the ammonium form. Ammonium nitrate is the preferred form of nitrogen fertilizer when it is to be applied on the soil surface and not incorporated.
