Rubidium oxide is the chemical compound with the formula Rb 2 O.Rubidium oxide is highly reactive towards water, and therefore it would not be expected to occur naturally. While the processes such as weathering, dissolution, mineralization, and desorption increase phosphorus availability in the soil for plant uptake, processes such as immobilization, adsorption, precipitation, runoff, and erosion decrease the phosphorus availability (figure 2). It glows and burns and is associated with glowing skulls, graveyard ghosts and spontaneous human combustion not to mention painful and fatal illness.

The person who lay afterwards in the bed, waking at night and feeling more than ordinary heat, perceived that the coverlet was on fire. Lemerys guest was lucky to survive: phosphorus burns with an incredible intensity and produces thick, choking white smoke (it is for this reason that white phosphorus has been used in incendiary bombs and to produce smoke screens). Phosphorus trichloride is very toxic and corrosive in nature, hence, it should not come in direct contact with eyes and skin. Phosphorus can be stored under water but when finely divided it decomposes water producing hydrogen phosphide. Explanation: Al + O2 Al2O3. 1. Double Replacement - the metals in ionic .
