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.
A molecular formula lists the numbers of the atoms of a specific element in a compound. A structural formula is a picture of how the atoms in a specific molecule are connected â¦ , with each atom represented by its chemical symbol.For example, oxygen's molecular formula is O2.or example: H2O2 is the molecular formula of hydrogen peroxide. In one molecule of hydrogen peroxide there are two atoms of hydrogen and two atoms of oxygen. This can be thought of as a 2:2 ratio of H:O. Reduced this ratio yields 1:1, and so the empirical formula is HO.
