What method of separation can be used to separate fuel with water?
One method that can be used to separate fuel from water is centrifugation. By spinning the mixture at high speeds, the denser water will separate from the less dense fuel, allowing for their separation. Alternatively, a separating funnel can also be used to allow the two liquids to separate based on their different densities.
When sand and gravel mix together is it reversible?
Yes, the mixing of sand and gravel is a physical change, which means it is generally reversible. You can separate sand and gravel by using methods like sieving or washing, as their different sizes and densities allow for such separation. However, the ease of separation may depend on the specific mixture and the method used.
What property of these metals would allow such a separation?
The different melting points of the metals would allow separation by heating the mixture to a temperature where one metal melts while the other remains solid, enabling them to be physically separated.
Is filtering a mixture a chemical or physical change?
it is a physical change because the appearance just changed.
How can seprate p-nitro acetanilide mixture of para and ortho acetanilide?
The amide group on acetanilide is an ortho/para director, so a simple nitration should work: a mixture of sulfiric acid and nitric acid should be sufficient. Afterward, separation of the ortho and para compounds (by column chromatography, probably) would be necessary.
What physical property would you allow you to separate a mixture of iron filling and soil?
a screen
When would it be easy to use only your hands to separate mixture?
It would be easy to use only your hands to separate a mixture when the components have distinct physical properties such as size, shape, or texture that allow you to pick them apart easily. If the components are large enough to be easily distinguishable and separate with your hands, then hand separation would work well.

How do you separate gasoline and water where gasoline forms the upper layer in the mixture?
Use a separatory funnel to pour the mixture into it and allow it to sit until the layers separate. Open the stopcock to drain off the lower water layer, leaving the gasoline in the upper layer. Repeat the process if necessary for better separation.
How can you separate kerosene oil and water?
Kerosene is less dense than water, so it will float on top. To separate them, pour the mixture into a separation funnel and allow time for the layers to settle. Then, open the stopcock and drain the kerosene layer from the bottom.

How would you separate gold from a mixture of gold and copper filings?
One method to separate gold from a mixture of gold and copper filings is by using a process called gravity separation. This involves shaking the mixture in water to allow the gold, being denser, to settle to the bottom while the lighter copper filings float on top. The separated gold can then be carefully collected and dried.
How do you remove emulsions during extraction?
To remove emulsions during extraction, you can try several methods. First, allow the mixture to sit undisturbed, which can help the emulsion separate naturally. If that doesn't work, gently heating the mixture can reduce viscosity and promote separation. Alternatively, adding salts or solvents that disrupt the emulsion's stability can help break it down, allowing for easier phase separation.
Is filtering a mixture a chemical or physical change?
it is a physical change because the appearance just changed.
If you made a mixture of iron fillings and salt how could you separate that mixture into its 2 original substances?
Place the mixture in water. You recover the iron once the salt dissolves. Then allow the water salt mixture to dry and allow salt crystals to reform.
How is it easier to separate a mixture of seashells and marbles than a copper sulfate soulution?
It is easier to separate a mixture of seashells and marbles because they have distinct physical properties, such as size, shape, and color, which allow for manual sorting. On the other hand, separating copper sulfate solution is more difficult because the components are both in liquid form and have similar physical properties, requiring a process like distillation or filtration to separate them effectively.
