What is the oxidation number of sulferin potash alum?
The sulfur in potash alum occurs in sulfate ions, which have the formula SO4-2. Since sulfur is less electronegative than oxygen, the oxygen has an oxidation number of -2; 4 atoms of oxygen give a total negative charge of -8, and the sulfur atom must have an oxidation number of +6 to match the -2 charge of the sulfate ion as a whole.
What two elements must a silicate have?
Silicon and oxygen.
What happens to the sulphur particles in order for them to become sulphur dioxide particles?
well sulfur dioxide is a covalent compound so the sulfur atoms and the oxygen atoms share valence electrons. This is because all three atoms must try to have an octet, and with only 18 total valence electrons this must be done through sharing. So to become sulfur dioxide, the valence electrons on the oxygen atoms must be shared with the valence electrons on the sulfur atom.
What must link up with this fuel to produce energy?
Oxygen
Why must no flammable elements be present when oxygen is in use?
Oxygen supports combustion, therefore no open flame or combustible products should be permitted when oxygen is in use.
What must be done if oxygen deficiency occurs 19.5 percent during a permit required confined space entry?
If oxygen levels fall below 19.5% during a permit-required confined space entry, all entrants must stop work immediately and leave the confined space. No one may reenter that space until testing shows that adequate oxygen levels have been restored.
If you have scleroderma and you now must use oxygen your breathing is not getting better?
I have scleroderma the doctors have now put me on oxygen 24/7 is there any thing eles that can be done
What condition must exist in cell for fermentation to occur?
Oxygen must be absent in the cell.
What happens if you have a hemoglobin deficiency?
The blood's oxygen transport mechanism depends upon hemoglobin, so a person with no hemoglobin would immediately succumb to anoxia, unless such a person were to be placed in a hyperbaric oxygen chamber.
Where does oxygen enter the blood and carbon dioxide leave the blood?
Oxygen must enter our blood and Carbon Dioxide must leave the blood through our lungs. They do so by diffusion between the cappillaries.
