What does SOAP stand for?
Introduction. The Subjective, Objective, Assessment and Plan (SOAP) note is an acronym representing a widely used method of documentation for healthcare providers.
Why does dish soap repel milk?
When you first put the detergent on the milk, the negative end of the detergent molecules line up with the positive end of the water molecules. This causes the detergent molecules to zoom out in every direction over the surface of the milk and push the food coloring out toward the edge of the plate.
Does dish soap break down grease?
Dish soap only temporarily breaks up the fat, oil, and grease. Further down the sewer line all that grease, oil, and fat will begin to congeal and cause a blockage.
Is adding food coloring to milk a chemical change?
Milk is made up of mostly water but it does contain vitamins, minerals, proteins and small droplets of fat. The soap and fat work hard to join together, which causes the movement. When food colouring is added we are able to witness this chemical reaction occurring.
Why is soap mixed with water answers?
The soap becomes chemically active when mixed with water. It works because soap is made up of molecules with two very different ends. One end of soap molecules love water – they are hydrophilic. The other end of soap molecues hate water – they are hydrophobic.
What would dissolve the best in water?
1 Answer. Polar solutes or ionic solids dissolve best in water.
What happens when you put soap in water?
Adding soap lowers the water’s surface tension so the drop becomes weaker and breaks apart sooner. Making water molecules stick together less is what helps soaps clean dishes and clothes more easily.
Why does pepper move away from dish soap in water?
Soaps and cleaners are designed to break down the surface tension of water. The water molecules, however, want to stick together and maintain that tension, so they move away from the soap, carrying the pepper with them!
What method would you use to separate ground pepper from water?
As a result, you can simply filter out the pepper using filter paper. Once you’ve done that, all you have to do is evaporate the water, and then you’ll be left with the leftover formerly dissolved salt.
What happened to the paper as you put a drop of liquid detergent to the water?
Answer: The paper clip is able to float due to the water’s surface tension. This is because the detergent acts as a surfactant, a substance that reduces the surface tension of the substance it is dissolved in, breaking the water’s surface tension.
What happens when you mix water and dishwashing detergent?
Detergent grabs onto both types of molecules causing oil droplets to be suspended in the water. When you shake the jar the detergent molecules adhere the water and oil together forming an emulsion. An emulsion is the combination of molecules that are not normally attracted to each other, that don’t usually mix.
Why does pepper sink in alcohol?
The surface tension of the water is high due to hydrogen bonding. The bits of pepper are small enough to be suspended on the surface of the water. However, the surface tension of isopropanol is much lower than that of water, allowing the pepper to sink to the bottom of the well.
How many drops of water can fit on a penny?
Were you surprised to discover that a lot more drops of water fit on a penny than you predicted? We had 27 drops of water on ours! Surface tension and cohesion is the reason you can get so many drops of water on a penny. Cohesion is the “stickiness” of like molecules to one another.
Why does a penny hold so many drops of water?
The attraction of water molecules to other substances, like soil or glass, is called adhesion. As drops of water are added onto a penny, the adhesive force between the water and the penny keeps the water from falling off. Cohesive forces are strong, but not unbreakable.
Why can you fit more drops of water than alcohol on a penny?
But alcohol has a different size and shape and has its polar part on one end. Alcohol molecules can meet at areas where they would not attract as strongly. The water is more attracted to itself than to the metal of the penny. The alcohol is a bit less attracted to itself so it spreads more on the penny.
Why does the heads side of a penny hold more water?
The results showed that heads was able to hold more droplets than tails since it had less carvings. When a penny has less carvings on one size than the other side, there will be different results since each side takes up a different amount of space.
Which side of a penny can hold more drops of water?
heads side
Why do pennies turn silver in zinc?
When a copper penny is heated in a solution of sodium hydroxide mixed with zinc dust, small amounts of zinc dissolve into the surface of the penny. This causes the penny to look silver since there is now a layer of zinc over the outside of the penny. The two metals, zinc and copper, do not react chemically.
How is the shape of a drop of water on a penny different from the shape of a drop of alcohol?
Though gravity is trying to pull all the water molecules down, toward the surface of the penny, the hydrogen bonds keep the water droplet in a spherical shape. Because alcohol is so much less polar, it can’t resist gravity, and all of the molecules are pulled down into a flat sheet over the penny’s surface.
