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 Sulfate As a Lawn Fertilizer. Ammonium sulfate is a water soluble fertilizer providing 21 percent nitrogen by weight and 24 percent sulfur. The guaranteed analysis is 21-0-0+24(S). It can be applied to lawns as a top dressing of nitrogen and sulfur with a broadcast or drop-type spreader.
