The radical of helium is He·. Helium does not naturally form radicals in the same way that other elements do, but in certain conditions it can form a radical by gaining an extra electron to become negatively charged.
A phenoxy radical is a type of reactive intermediate in organic chemistry that contains a phenyl ring (benzene ring) with an oxygen atom attached to it. Phenoxy radicals are commonly involved in radical reactions and can be stabilized by resonance delocalization of the unpaired electron around the phenyl ring.
CO common meaning is the chemical formula of carbon monoxide. Also the carbonyl group (C=O).
The radical with four carbon atoms and nine hydrogen atoms is the butyl radical, specifically the n-butyl radical. It is a short-lived species that is highly reactive due to having an unpaired electron. It is commonly encountered in organic chemistry reactions involving radical intermediates.
"HO2" typically refers to the hydroperoxyl radical, which is a reactive oxygen species formed in the atmosphere. It plays a role in chemical reactions that can lead to the formation of pollutants like ozone and can contribute to air quality issues.
The formula for the sulfate ion is SO4^2-.
The chemical formula for thiosulfate radical is S2O3^2-. It consists of a central sulfur atom bonded to three oxygen atoms in a trigonal planar arrangement.
The structural formula of a phosphate radical is PO₄³⁻. It consists of one phosphorus atom bonded to four oxygen atoms, with a net charge of -3.

I assume you mean x(squared) + 4x - 10. Solving this isn't extremely difficult if you know the quadratic formula. first of all, remember the form ax(squared) + bx + c you are currently in that form. so, the formula is (-b +OR- radical(b(squared) - 4ac)) /2a so, using the formula, you will get (-4 + or - radical(16 - 4(1)(-10)))/2(1) this simplifies to (-4 + or - radical(56)) / 2 this can simplify to (-4 + or - radical(4) * radical(14)) / 2 the 2 in the denominator cancels out with the -4 and the 2(comes from radical(4)) in the numerator. this leaves us with -2 + or - radical(14) these are the two solutions. x= -2 + radical(14) x = -2 - radical(14) this may seem complex since it's hard to explain in this way, but I promise you will understand it. here is an easier to understand version of the quadratic formula.
The chemical formula for methylene is CH2. It is a highly reactive and short-lived radical that is involved in various chemical reactions.
The name of NH4+ is ammonium ion. Its chemical formula is NH4+.
If there is any acid radical present, it is one with the formula O2-2. However, hydrogen peroxide is not usually considered an acid except by the broadest definition(s) of acid behavior.
