Oxygen will diffuse faster as oxygen is a gas and bromine is a liquid
The respiratory system uses the diffusion of oxygen and carbon dioxide. You inhale the oxygen which goes through the alveoli and thew capillaries in the lungs and you exhale it through the same section you inhale from. Therefore they diffuse together.

Bromine is often thought of as a gas but as it has a boiling point of 58.8 °C (137.8 °F) it exists as a liquid at room temperature. The confusion arises as the bromine evaporates by diffusion and creates a noticeable odour at lower temperatures in the same way that water evaporates below 100 °C . At a temperature of  -7.2 °C (19 °F) bromine becomes a solid.
Fluorine because it is in the same group (group 17) as Bromine therefore it has the same chemical properties
no the do not bromine has 4 and oxygen has 2
The rate of diffusion in gelatin at room temperature is very slow. This is especially compared to the rate of diffusion in water at the same temperature.
Before diffusion there is a higher concentration of oxygen molecules outside the cell than inside the cell. After diffusion the concentration of oxygen molecules is the same outside and inside the cell.
Same as anywhere else on the cell. The function of the villi is to increase the surface area, and thus the rate of diffusion.
No. There are essentially three different capillaries that differ in the rate of diffusion.

Diffusion will constantly take place. However the net transfer of particles will cease when a concentration equilibrium occurs. I.e. you have a piece of iron with 0% carbon. you put it into a 20% carbon atmosphere. The carbon will diffuse into the iron until the concentration of carbon is the same in both the iron and the atmosphere. Diffusion will then still occur, but there will be diffusion to the bar and diffusion from the bar at the same rate.
Osmosis is the same thing as diffusion, but occuring only with liquids in a selectively permeable membrane. An example of this is that water entering your cells is osmosis, but oxygen entering is diffusion.

It's BROMINE. That is the element that is a liquid in the same period as Fe.
Lol, you're probably in my chem class doing the same lab. I'm trying to figure out the same thing.
