One of the main differences that can be seen is that cardiac muscles are involuntarily controlled, whereas the somatic nervous system controls the ovement of the skeletal muscles. Cardiac muscles and skeletal muscles are also different in their shape.While the cardiac muscles are semi-spindle, the skeletal muscles are cylindrical in shape. Another difference is that the cardiac muscles are short in comparison to skeletal muscles.. Cardiac muscles are involuntarily controlled, whereas the somatic nervous system controls the movement of the skeletal muscles. 2. While the cardiac muscles are semi-spindle, the skeletal muscles are cylindrical in shape. 3.
The chemical compound potassium chloride (KCl) is a metal halide salt composed of potassium and chloride. It is odorless and has a white or colorless vitreous crystal appearance.The solid dissolves readily in water and its solutions have a salt-like taste.KCl is used in medicine, scientific applications, food processing, and used to cause cardiac arrest as the third drug in the three drug cocktail for executions by lethal injection.rally, potassium chloride is toxic in excess; the LD50 is around 2.5 g/kg (meaning that a lethal dose for 50% of people weighing 75 kg (165 lb) is about 190 g (6.7 ounces)).
Lesson Summary. Potassium chloride is an ionic compound and is a salt that naturally occurs as a solid that has a powdery and crystalline appearance. Its chemical formula is KCl: it consists of one potassium (K+) ion and one chlorine (Cl-) ion.Potassium chloride has so many uses in various fields.It is a main component of fertilizer, and in medicine, it treats a condition called hypokalemia, which results when potassium levels in blood are lower than normal.ere, we can see that KCl consists of a positive ion (K+) and a negative ion (Cl-). Salts are ionic compounds consisting of positive and negative ions. Because potassium chloride has ions of opposite charges, potassium chloride is classified as a salt.
