Why is vanadium pentoxide yellow in colour?
because the arrangement of the oxygens in the crystal structure sets the energy difference between a molecular orbital energy level and its excited state to correspond to that wavelength of light. If you change the orientation of the oxygens, change the number of oxygens or change the ligands to something altogether different, the difference in molecular orbital energy levels will also change. The new energy difference will correspond to a new color.
What does 3 mean in Al2o3?
There are 3 oxygens
What is the physical state of the products?
A physical state of a substance is whether it is solid, liquid, or gas.
Which is A change in size shape or state of matter?
a change in size, shape or the state of matter is a physical change. True for A+.
How many oxygens are in the formula for the phosphide ion?
There are no Oxygen in the Phosphides
What is oxygens natural state?
a gas
What is oxygens state?
Colourless gas
What is the combining form for oxygen?
Oxygens liquid state
What is oxygens state of matter when it is 120 degrees Celsius?
A gas.
What is oxygens state at room temperature?
oxygen is a gas at room temperature
What is the oxidation state of Cr in SrCr2O7?
+6This compound has dichromate in it (Cr2O7-2). Oxygen almost always has an oxidation state of -2, which means the total charge for the oxygens is -14. The charge on the two chromates combined needs to be two less than the total charge on the oxygens because the ion has an overall charge of -2. Thus, the oxidation state for Cr is +6.
What is oxygens charge?
2-
What is oxygens oder?
it has no oder .
What is oxygens atomic number?
Oxygen is in p block. it is a useful gas. oxygens atomic number is 8.

Is the physical state a physical or a chemical?
it is a physical
Is boiling water a physical change?
The water leaving as steam has undergone a physical change from a liquid state to a gaseous one. No chemical change has occured because it is still H2O.Basic explanation:H2O(liquid) + heath H2O(gaseous)+ ...Water passes from a liquid form to gaseous, through an active physical process called : "evaporation", that occures with the help of a source of enery (heater).=> When the H2O molecule is heaten up, physical reactions occurs:- excitement (disorder increase, "molecules are increasingly kegeling" )- breaking of the hydrogen bridges/connections between the: "O" (oxygens) and "H" (hydrogens), liberating them from their actractive forces through the process of gasification.... In the end:=> Final global composition : When water boiles molecules "stay unchanged", they are the same H2O in vapour as before in liquid state.----------------------------------------------------------------------------------------------------This is (by definition) physical (like any change in state of matter is physical).
