MRI vs. MRA. An MRA, or magnetic resonance angiogram, is a type of MRI scan that uses MRI's magnetic fields and radio waves to produce pictures of blood vessels inside the body, allowing doctors to locate problems that may cause reduced blood flow.
Best Answer: Ethyl alcohol, at the concentrations used in most antibacterial preparations, kills bacteria by disrupting membranes and by denaturing proteins. Ethylalcohol is miscible in water (that is, completely soluble). But ethyl alcohol can also dissolve in the membranes of cells.
Isopropyl Alcohol. Isopropyl alcohol, which is also known as 2-propanol, has the same molecular formula as propanol. The molecular weight of it is around 60 g mol-1. The molecular formula is C 3 H 8 O. Hence, isopropyl alcohol is an isomer of propanol. The hydroxyl group of this molecule is attached to the second carbon atom in the chain. Therefore, this is a secondary alcohol. Melting point of isopropyl alcohol is -88 o C, and the boiling point is 83 o C. It is miscible with water and stable under normal conditions. This is a colorless, clear, flammable liquid.
