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 molecular formula is an important piece of information for any chemical compound. The molecular formula tells you which atoms are present in the compound, and how many of each are present. You will need to know the empirical formula to calculate the molecular formula, and you will need to know that the difference between these two formulas is a whole number multiplier.
