Which particle would have the slowest rate of deposition?

round particle
very large particle
particle with sharp ends
particle with a high density

c) particle with sharp ends

Explanation:

Rate of deposition of a particle determines how fast a particle of given characteristics (size, shape etc) will settle onto a surface. This is explained in terms of the Stokes law, according to which the frictional force (F) or the Stokes drag acting between the particle and the medium is proportional to the particle radius (R), flow velocity (v) and viscosity (μ)

F =  6πμRv

The frictional force which is essentially offers resistance to the flow will be the highest for irregularly shaped particles particles in this case those with sharp ends. As a result, these particles would have the slowest rate of deposition.

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.

it's all four options.
