No, boric acid can still be very dangerous to humans, animals, and children. It may requires a lot of it for a lethal dose, but there are also several side effects of exposure to boric acid. Many of the insecticides that contain boric acid will contain a sweetener, such as sugar, to attract insects.
Within a water molecule is covalent bonds. between water molecules are hydrogen bonds.
Hydrogen Bonding and Water. Hydrogen bonds account for some important qualities of water. Even though a hydrogen bond is only 5% as strong as a covalent bond, it's enough to stabilize water molecules. 1  Hydrogen bonding causes water to remain liquid over a wide temperature range. 2  Because it takes extra energy to break hydrogen bonds, water has an unusually high heat of vaporization. Water has a much higher boiling point than other hydrides. There are many important consequences of the effects of hydrogen bonding between water molecules: Hydrogen bonding makes ice less dense than liquid water, so ice floats on water.
