Why don't the T cells and macrophages do their job of recognizing and fighting the HIV virus? 1. They do not recognize the HIV virus as bad
2. The HIV virus hides so it is not seen
3. The HIV virus infecst the macrophages and T cells
4. The HIV virus goes where there are no macrophages and T cells​

Water ionizes by the equation h2o(l)⇌h+(aq)+oh−(aq) the extent of the reaction is small in pure water and dilute aqueous solutions. this reaction creates the following relationship between [h+] and [oh−]: kw=[h+][oh−] keep in mind that, like all equilibrium constants, the value of kw changes with temperature.

If 34.2 grams of lithium react with excess water, how many liters of hydrogen gas can be produced at 299 kelvin and 1.21 atmospheres? 2 li (s) + 2 h2o (l) yields 2 lioh (aq) + h2 (g)

At element makes up all organic compounds?
