under the same conditions carbon (iv) oxide, propane and nitrogen (i) oxide diffuse at the same rate. Explain

Rate of diffusion is same .

Explanation:

As we know that Rate of the diffusion is directly proportional to the .They have same mass if there is same rate and similar condition therefore the mass of carbon (iv) oxide,propane and nitrogen (i) oxide will be similar.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
