Similarly, the muscles that maintain our posture contract and relax in a synchronized fashion. If the spasm is forceful and sustained, it becomes a cramp. A muscle cramp is an involuntarily and forcibly contracted muscle that does not relax. Muscle cramps cause a visible or palpable hardening of the involved muscle. Muscle cramps can last anywhere from a few seconds to a quarter of an hour or occasionally longer.
CH3COOH is the chemical formula for acetic acid (vinegar). It is also called ethanoic acid. It is considered to be a weak acid as it is only a partially dissociated acid in water.
CaCo3 is a base, so it neutralizes acids. Thus, CaCo3 can neutralize acids in acid rain. For example, CaCo3 will neutralize HCl by the following equation:  2HCl(aq) +CaCO3(a â¦ q) reacts to form CaCl2(aq) + H2O(l) + CO2(g)  This gets rid of the acids and makes the acid rain safe for organisms.hus, CaCo3 can neutralize acids in acid rain.
