Over the Counter Medications Drugs that are safe and effective for use by the general public without a prescription are defined as over-the-counter (OTC) drugs. These drugs are often located on shelves in pharmacies with easy access by patients, but may also be located in non-pharmacy outlets, such as grocery stores, convenience marts and large discount retailers.
Objects simply do not acquire charges on the order of 1.00 Coulomb. In fact, more likely Q values are on the order of 10-9 or possibly 10-6 Coulombs. For this reason, a Greek prefix is often used in front of the Coulomb as a unit of charge. Charge is often expressed in units of microCoulomb (ÂµC) and nanoCoulomb (nC).
In nuclear physics and chemistry, the Q value for a reaction is the amount of energy released by that reaction. The value relates to the enthalpy of a chemical reaction or the energy of radioactive decay products. It can be determined from the masses of reactants and products. Q values affect reaction rates. In general, the larger the positive Q value for the reaction, the faster the reaction proceeds, and the more likely the reaction is to favor the products.
