One large drop of rain, or as many as 20 average-sized drops of water from an eyedropper, given maximum surface tension. As many as 35 of the smallest drops can hold together atop the coin.
Because the hydrogen molecules in water want to stay connected and once you add soap it messes with the bonds and and they don't stay bonded as strongly. Also the mass and density of the water changes when you add soap.
There is only so much space between water molecules for sugar molecules to fit.
Hydrogen bonding. Water is a polar molecule so it is slightly negatively and positively charged on different ends and this leads to cohesion of the molecules; one to another. Alcohol is nonpolar.
32 electrons can fit
2 can fit in the first energy level, 8 can fit in the second, and there is an infinite number that can fit in the 3rd.

The controlled variable is the penny. The independent variable is the water. The dependent variable is the amount of water able to fit on the penny.
Alot of drops fit because if you keep the surface tension from moving then you could put as much drops as you can.] ==If you put a penny on a flat surface and keep its tension and keep the penny from moving you can put as much drops as you can till it leaks off. You cant put as much as you want cause the penny will overflow. its not a big object?
I would say 35 drops!
About 10
it depends on the size of the mouth
Ideally, everyone performing the experiment would include the following: - distilled waterThere are a lot of factors involved. The cohesion and adhesion ('stickiness') of water molecules can be effected by things like oils (on surface pennies from peoples' skin) and other contaminates on the penny. The size of the dropper or pipette will determine the size of each water droplet - the larger the drop, the fewer number of drops will fit on the penny. The manner in which the water is added to the penny is also a factor. Water has a cohesive nature (the molecules are kind of like magnets and are attracted to one another). Therefore, if the drop from the pipette is allowed to touch the water already on the surface of the penny, the water can be 'pulled' out of the dropper. When this happens, the size (volume) of the drop is not always the same - it could be a very small amount (which will result in a very large number of drops), or a large amount. Soap causes the cohesiveness ('stickiness') of the water molecules to decrease so they are not as strongly attracted to each other. Because of this, when soap is added to the water the number of drops that can be placed on the penny will decrease. The water molecules can't 'stick' together as well, so the water on top of the penny spills off sooner than it would with non-soapy water. Ideally, everyone performing the experiment would include the following: - distilled water (to start with) - same type/size of calibrated dropper/pipette - same date of penny - penny cleaned as thoroughly as possible using same cleaning procedure - same 'dropping' procedure

It all depends on if you drop the water fast or if you drop it slow. Ideally, everyone performing the experiment would include the following: - distilled waterThere are a lot of factors involved.
