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.
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.
How will you separate a mixture of kerocene oil and water?
You can separate a mixture of kerosene oil and water using the method of decantation. Allow the mixture to sit undisturbed until the two liquids separate into distinct layers. Then carefully pour off the kerosene oil layer, leaving the water behind.
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.
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.
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.
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.
Which method could be used to obtain copper from a mixture of powdered copper and sodium chloride?
Electrolysis can be used to separate copper from a mixture of powdered copper and sodium chloride. By passing an electric current through the mixture, the copper ions will be attracted to the negative electrode (cathode) where they will be reduced and deposited as solid copper. This process will allow the separation of copper from the sodium chloride.
What physical property would allow you to seprate a mixture of iron filings and soil?
