How do you get tape adhesive off your arm caused by an iv?
Either use soap & water, or an alcohol-based liquid (such as anticeptic). BOth methods will break-down the adhesive.
Is wax adhesive or cohesive?
It is both. Anybody who has stuck a candle onto a candle base plate know that you first drip hot wax onto the plate and then quickly affix the candle to the wax before it cools and hardens. The wax sticking to the plate is adhesion, the wax sticking to itself is cohesion.
Which is true about sugar dissolving in water Sugar is the solvent and water is the solute. Both sugar and water are solvents. Sugar is the solute and water is the solvent. Both sugar and water are so?
One is going to be the solvent and one will be the solute, they can't be both at the same time. You usually put sugar into something such as water or tea or soda. That makes the sugar the solute (goes into) and the other, like water, the is the solvent. A good way to remember this is that the solvent is the part of a solution present in the largest amount.
Why is water harmless and hydrogen peroxide is poisionous given that both are compounds of hydrogen and oxygen?
Because the extra oxygen atom makes peroxide much more chemically reactive and unstable than water.
What are propane and water both examples of?
Propane and water, are both examples of Compounds.
If water spreads out on a glass plate is this an example or cohesive or adhesive force?
Both, the water molecules are cohesive to each other, and the outer water molecules are adhesive to the table surface.
Can you give some sentences using the word cohesive?
Water molecules are both cohesive and adhesive: they can stick together or stick to other surfaces.
What special abilities do water molecules have because they are polar?
Because water molecules are polar, they exhibit both cohesion adhesive. They are cohesive because they stick to other water molecules, and adhesive because they also stick to other surfaces.
Why is water both adhesive and cohesive?
Cohesion in water is the water being 'sticky' or attracted to itself. Adhesion in water is when the water is 'sticky' or attacted to other surfaces. Water is cohesive and adhesive because of it's properties. The oxyogen and hydrogen molecules are bonded together and are polar. Beacuse the molecules are polar the particales are therefore attracted to each other from negative to positive end (cohesion), but are also atracted to other particles in other surfaces, again positive to negative poles (adhesion). It's very important that water be both cohesive and adhesive for being good for solutions and other functions.
2 How can you explain Cohesion and adhesion in term of water molecules?
Water has both cohesive and adhesive forces. They are similar.The cohesive of water describes how the molecules of water are attracted to one another. We observe the cohesive forces of water when we see a drop of water sitting on a surface. The water does not spread because the molecules are attracted to one another. Surface tension of water is due to its cohesive properties.The cohesive forces of water are due to hydrogen bonding between molecules.Adhesive properties of water are how the molecules are attracted to other substances. We observe the adhesive forces of water when we see the edge of water in a glass is attracted up on the sides of the glass. This is most apparent when the diameter of the glass vessel is less than a centimetre. It is called a meniscus. Trees use this adhesive property of water to help suck water up from the ground. If the diameter of the glass is small enough, as in a glass capillary, the water will rise up the tube by itself due to adhesive forces.
Why does alcohol cling to a glass rod while mercury does not?
Cohesion is the tendency of molecules to be attracted to similar molecules. Adhesion is the tendency of molecules to be attracted to dissimilar molecules.Water is both cohesive and adhesive, as is ethanol alcohol. The cohesiveness of water can be demonstrated by filling a cup with water and placing a wet clothe over the top of the cup, then flipping the cup upside down. The water will not entirely spill out of the cup.Mercury is cohesive, but not adhesive, so two drops of mercury will absorb one another, but dipping a clothe in mercury will not absorb it.The phenomenon of cohesion and adhesion can be understood by looking at the molecular structure and charge distribution of a molecule.

Either use soap & water, or an alcohol-based liquid (such as anticeptic). BOth methods will break-down the adhesive.
Why water is said to be common place but unique?
I don't quite understand what you're asking but water is said to be common because of both it's importance to life and chemistry and the fact that it is so widespread. Water is unique because it has two unique properties being both it's adhesive and cohesive nature. it is also called as unique because you can't live there unless aquatic animals.It is also unique because humans can't live there except aquatic animals.
What is the best adhesive to stick vinyl base to bathroom wall?
100 % silicone, because it's both water and mildew proof.
What is good adhesive for nylon and PE?
There is no good adhesive for nylon and PE. Both are almost impervious to glue.
