Healing time is different depending on the part of your body that you get pierced. Some parts are more likely to get infected or have problems. Piercings on your ear lobes usually take about 6-8 weeks to heal. However, piercings on the side of your ear (cartilage) can take anywhere from 4 months to 1 year to heal.
By Anne Marie Helmenstine, Ph.D. Molecular Equation Definition: A molecular equation is a balanced chemical equation where the ionic compounds are expressed as molecules instead of component ions. Examples: KNO 3 (aq) + HCl(aq) â KCl(aq) + HNO 3 (aq) is an example of a molecular formula.
The empirical formula is the simplest formula for a compound. A molecular formula is the same as or a multiple of the empirical formula, and is based on the actual number of atoms of each type in the compound.or example, if the empirical formula of a compound is C 3 H 8, its molecular formula may be C 3 H 8, C 6 H 16, etc. An empirical formula is often calculated from elemental composition data. The weight percentage of each of the elements present in the compound is given by this elemental composition.
