conservation of mass. These results do not obey the law of conservation of mass. Possibly she made a mistake recording her numbers. 28. When 31 g of phosphorus reacts with oxygen‚ 71 g of an oxide of phosphorus is the product. What mass of oxygen is needed to produce 13 g of this product? 31g + x = 71g 71g - 31g = 40g oxygen This means that in

a beneficial therapy for children with Cerebral Palsy? Background: Hyperbaric Oxygen Therapy (HBOT) is being promoted as a new therapy for children afflicted with cerebral palsy. It is being utilized by several specialized medical centers in the US‚ Europe and Canada. The rationale behind this therapy is inhalation of pressurized pure oxygen within a hyperbaric chamber‚ results in higher levels of dissolved oxygen within the blood (Liptak‚ 2005).

Describe how hydrogen bonding occurs between water molecules‚ and relate this and other properties of water‚ to the roles of water in living organisms. Water is a very small molecule‚ consisting of two hydrogen atoms covalently bonded to an oxygen atom. However the electrons shared are not done so equally‚ oxygen is more electronegative and has a firmer hold on the electrons and pulls them slightly towards its nucleus. Due to this‚ the charge across the molecule of water is not equally distributed
