The hydroperoxyl radical, also known as the hydrogen superoxide, is the protonated form of superoxide with the chemical formula HO 2, also written HOO •. This species plays an important role in the atmosphere and as a reactive oxygen species in cell biology. [2] The molecule has a bent structure. [3] The p Ka of HO 2 is 4.88.

2022年8月8日 · An HO-2 policy is a form of homeowners insurance that provides less coverage than a standard homeowners insurance policy. This policy type has been all but phased out of the marketplace.

2019年4月14日 · HO-2 — Designates a "broad form" homeowners insurance policy that provides insurance coverage on a "named-peril" basis. There are 16 covered perils on a broad form policy. They are: HO-3 — Designates a "special form" homeowners insurance policy that provides insurance coverage for the structure of your home on an "open-peril" basis.

2022年6月7日 · The primary difference between HO2 and HO3 home insurance policies is the way your dwelling is covered. With HO2 coverage, your dwelling coverage is written as named perils which means that your home structure is only covered by perils included in your policy.

2023年9月15日 · The hydroxyl (OH), hydroperoxy (HO2), and organic peroxy (RO2) radicals play important roles in atmospheric chemistry. In the presence of nitrogen oxides (NOx), reactions between OH and volatile organic compounds (VOCs) can initiate a radical propagation cycle that leads to the production of ozone and secondary organic aerosols.

s: Strong: vs: Very strong: o: Energy separation between the v = 0 levels of the excited and electronic ground states. x: Energy separation between the band maximum of the excited electronic state and the v = 0 level of the ground state.

1995年6月20日 · The self-reaction of the HO 2 radical is an important termination reaction for HO χ and it is the major gas phase source of hydrogen peroxide in the atmosphere. It is well established that the rate of this reaction is sensitive to both …

2025年2月5日 · What is an HO-2 policy? An HO-2 policy is a type of home insurance that is written on a named-perils basis. This means it only covers damage to your property that’s caused by one of the perils identified in the policy. Some HO-2 policies also cover your personal property and personal liability.

2004年7月6日 · HO 2 •, usually termed either hydroperoxyl radical or perhydroxyl radical, is the protonated form of superoxide; the protonation/deprotonation equilibrium exhibits a pK a of around 4.8. Consequently, about 0.3% of any superoxide present in the cytosol of a typical cell is in the protonated form.
