  2. Hinkley groundwater contamination - Wikipedia

    en.wikipedia.org/wiki/Hinkley_groundwater...

    A 2007 toxicity report for the National Toxicology Program provided evidence that high doses of chromium 6 caused cancers of the gastrointestinal tract in rats and mice at levels higher than 5 mg/L of water, (5 ppm, or 5,000 ppb). [41] [42] Average hexavalent chromium levels in Hinkley were recorded at 1.19 ppb, with an estimated peak of 20 ppb.

  3. Carbon monoxide - Wikipedia

    en.wikipedia.org/wiki/Carbon_monoxide

    Carbon monoxide (chemical formula CO) is a poisonous, flammable gas that is colorless, odorless, tasteless, and slightly less dense than air. Carbon monoxide consists of one carbon atom and one oxygen atom connected by a triple bond. It is the simplest carbon oxide. In coordination complexes, the carbon monoxide ligand is called carbonyl. It is ...

    On Microsoft consoles, Edge replaced IE as the dominant browser a few months after its release in 2015. [201] Market share varies by region. On some days of the week, Edge takes second place with a 10.02% share in the US on PC, and Firefox and Edge have a very similar share globally, switching places for second and third depending on the day.

  5. Reducing agent - Wikipedia

    en.wikipedia.org/wiki/Reducing_agent

    This is commonly expressed in terms of their oxidation states. An agent's oxidation state describes its degree of loss of electrons, where the higher the oxidation state then the fewer electrons it has. So initially, prior to the reaction, a reducing agent is typically in one of its lower possible oxidation states; its oxidation state increases ...

    The highest occupied molecular orbital of CO is a σ MO Energy level scheme of the σ and π orbitals of carbon monoxide The lowest unoccupied molecular orbital (LUMO) of CO is a π* antibonding MO Diagram showing synergic π backbonding in transition metal carbonyls. Carbon monoxide bonds to transition metals using "synergistic pi* back ...

    Meanwhile, carbon monoxide poisoning also remains a concern for officials. The Centers for Disease Control and Prevention estimates that 420 Americans a year die from carbon monoxide poisoning.

  8. Oxidation state - Wikipedia

    en.wikipedia.org/wiki/Oxidation_state

    Carbon monoxide exemplifies a Lewis structure with formal charges: To obtain the oxidation states, the formal charges are summed with the bond-order value taken positively at the carbon and negatively at the oxygen. Applied to molecular ions, this algorithm considers the actual location of the formal (ionic) charge, as drawn in the Lewis structure.
