Individuals in most countries can get first aid training through courses offered by community health organizations and hospitals. Training may last anywhere from a few hours to three or four days, depending on the scope of a program.
Manganese is a pinkinsh-gray, chemically active element. It is a hard metal and is very brittle. It is hard to melt, but easily oxidized. Manganese is reactive when pure, and as a powder it will burn in oxygen, it reacts with water (it rusts like iron) and dissolves in dilute acids.Applications. Manganese is essential to iron and steel production. At present steel making accounts 85% to 90% of the total demand, most of the total demand.anganese is reactive when pure, and as a powder it will burn in oxygen, it reacts with water (it rusts like iron) and dissolves in dilute acids.

MnO4 redirects here. For the manganate ion MnO 4 2â , see Manganate. A permanganate is the general name for a chemical compound containing the manganate(VII) ion, (MnO 4 â). Because manganese is in the +7 oxidation state, the permanganate(VII) ion is a strong oxidizing agent.The ion has tetrahedral geometry. H+ + MnO 4 â + 5 e â â Mn 2+ + 4 H 2 O. In a strongly basic solution, permanganate(VII) is reduced to the green +6 oxidation state of the manganate ion, MnO 4 2â .
