How many 8.5 x 11 sheets of paper does it take to reach the moon?
25 distances
How many sheets of toilet paper are there in a single roll?
Each brand of paper towel has a different amount.
What is the least count of graph paper?
The least count of graph paper is determined by the smallest measurable unit on the paper, typically represented by the smallest division or grid square. This value is essential for accurately measuring distances and plotting points on the graph. The least count can vary depending on the type of graph paper, with common values including 1 mm, 0.5 mm, or even 0.1 mm.
How much does 1 box of 8.5 x 11 paper weigh?
You need more information. You need to know how much paper you are dealing with (a ream, or some other sheet count) and also the specific grade of paper. Reams of different paper can weigh differently.
How many different circles can you make if you take a paper clip and 2 pencils?

Why different compounds travel different distances on the piece of paper?
i think that it is because some compounds are more dense than others so they don't move that much or that far as others do. Whereas other compounds are "thinner" than some and can move with more ease causing them to travel greater distances. It also has to do with the amount of friction between the paper and the certain compound.
Why do pigments travel different distances up filter paper?
It depend on the density of the pigments.
What do the strips in the paper represent?
The strips in paper chromatography represent the different components of a mixture being separated based on their solubility and affinity for the stationary phase. Each strip shows the individual compounds in the mixture as they travel at different rates through the paper due to their interactions with the mobile phase.
What role does the stationary phase play in paper chromatography and how does it affect the separation of compounds"?
The stationary phase in paper chromatography acts as a medium for separating compounds based on their different affinities for the stationary phase and the mobile phase. It affects the separation of compounds by slowing down the movement of different compounds at different rates, allowing them to separate based on their interactions with the stationary phase.
Why did different dyes travel up the filter paper at different rates in paper chromatography?
different dyes travel with different speed/rates on filter paper in paper chromatography as they have nothing to do with the filter paper as it is the stationary medium while the rates depends upon the interaction between the solute i.e., dyes and the mobile phase i.e., the solvent.
How do you separate those in fountain pen ink?
To separate the components in fountain pen ink, one common method is chromatography. This involves placing a small sample of the ink on a suitable material (like filter paper) and allowing a solvent to travel up the paper, separating the components based on their solubility and affinity for the solvent. The different components will travel different distances, creating distinct bands that can be analyzed.
Why do different colors travel at different speeds?
Different colors of light travel at different speeds because they have different wavelengths. In mediums like air, water, or glass, shorter wavelengths (like blue and violet light) travel slightly slower than longer wavelengths (like red and orange light), leading to the separation of colors we observe in phenomena like rainbows or prisms.
What is paper chromatography used for?
Paper chromatography is a method used for separating out different components of solution. The most common classroom use for it is to visually see the different colored dyes in ink because the different colors will travel different lengths across the paper.
Why do colors show up on paper chromatography?
Colors show up on paper chromatography because different compounds in the mixture will travel at different rates on the paper. As the solvent moves up the paper, the compounds separate based on their affinity for the paper and the solvent, resulting in distinct colored bands that can be visually observed. Each compound absorbs different wavelengths of light, resulting in different colors being displayed.
What is function of butanol in paper chromatography?
Butanol is used as a solvent in paper chromatography because it can dissolve a wide range of compounds. It helps to carry the sample and allow it to migrate up the paper. Butanol also helps in separating the components of the sample by interacting differently with different compounds.
How does erasable ink work and what makes it different from traditional ink?
Erasable ink contains special compounds that allow it to be easily removed from paper using friction or heat. This is different from traditional ink, which permanently bonds with the paper fibers.
What type of change is burning of paper?
Burning paper is a chemical change. The paper reacts with Oxygen in the atmosphere to produce Carbon Dioxide, Water and other compounds [exactly which other compounds is dependent upon the composition of the burnt paper]
