No piercing is considered fully healed until it's a year old. Contrary to what you may read, it takes the body a full year to season a piercing to the point where it can be removed for extended periods of time without the risk of the piercing closing.
HBr is polar. The Lewis structure shows a central carbon atom forming four single covalent bonds with the four terminal bromines. The central carbon has no lone pairs and four bonding pairs, so the molecular geometry is tetrahedral (as is the electron geometry), and bond angles are thus approximately 109.5 degrees.
Have you heard of Wikipedia. HBr leads to this. Hydrogen bromide is the diatomic molecule with the formula HBr. HBr is a colorless gas that condenses to a colorless liquid. Hydrobromic acid is a solution of HBr in water. Hydrogen bromide and hydrobromic acid are, therefore, not the same, but they are related.
