  2. Barium nitrate - Wikipedia

    en.wikipedia.org/wiki/Barium_nitrate

    Barium nitrate is the inorganic compound with the chemical formula Ba(NO 3) 2. It, like most barium salts, is colorless, toxic, and water-soluble. It burns with a green flame and is an oxidizer; the compound is commonly used in pyrotechnics. [4]

  3. Oxygen - Wikipedia

    en.wikipedia.org/wiki/Oxygen

    The bond can be variously described based on level of theory, but is reasonably and simply described as a covalent double bond that results from the filling of molecular orbitals formed from the atomic orbitals of the individual oxygen atoms, the filling of which results in a bond order of two.

  4. Barium oxide - Wikipedia

    en.wikipedia.org/wiki/Barium_oxide

    Barium oxide, also known as baria, is a white hygroscopic non-flammable compound with the formula BaO. It has a cubic structure and is used in cathode-ray tubes, crown glass, and catalysts. It is harmful to human skin and if swallowed in large quantity causes irritation. Excessive quantities of barium oxide may lead to death.

  5. Nitrite - Wikipedia

    en.wikipedia.org/wiki/Nitrite

    In valence bond theory, it is described as a resonance hybrid with equal contributions from two canonical forms that are mirror images of each other. In molecular orbital theory , there is a sigma bond between each oxygen atom and the nitrogen atom, and a delocalized pi bond made from the p orbitals on nitrogen and oxygen atoms which is ...

    The handling of this chemical may incur notable safety precautions. It is highly recommend that you seek the Material Safety Datasheet for this chemical from a reliable source and follow its directions.

  7. Color of chemicals - Wikipedia

    en.wikipedia.org/wiki/Color_of_chemicals

    The color of chemicals is a physical property of chemicals that in most cases comes from the excitation of electrons due to an absorption of energy performed by the chemical. The study of chemical structure by means of energy absorption and release is generally referred to as spectroscopy.

  8. Barium nitrite - Wikipedia

    en.wikipedia.org/wiki/Barium_nitrite

    Barium nitrite is a chemical compound, the nitrous acid salt of barium. It has the chemical formula Ba(NO 2) 2. It is a water-soluble yellow powder. It is used to prepare other metal nitrites, such as lithium nitrite.

  9. Pauling's principle of electroneutrality - Wikipedia

    en.wikipedia.org/wiki/Pauling's_principle_of...

    There are two possible structures for hydrogen cyanide, HCN and CNH, differing only as to the position of the hydrogen atom. The structure with hydrogen attached to nitrogen, CNH, leads to formal charges of -1 on carbon and +1 on nitrogen, which would be partially compensated for by the electronegativity of nitrogen and Pauling calculated the net charges on H, N and C as -0.79, +0.75 and +0.04 ...
