When water evaporates from a body of water what kind of sediment is left behind?
The sediment is a mixture of sand, soil, salts, detritus.
What is decanting?
'''''Decantation''''' is a fast method for separating a mixture of a liquid and a heavier solid. In this process , first the solid impurities are allowed to sediment at the bottom of the container. Then, the pure liquid is poured out carefully from the container into another container. The precipitate or solid is left behind at the bottom of the container.
Why do you have to filter the mixture?
To get rid of any residue that is left behind. Eg) a mixture of water and sand. You filter the sand because you only want the water.
When a liquid form a solution evoporate the?
When a liquid from a solution evaporates the solute will be left behind,e.g salt water,when the water evaporates only the salt will be left and that salt would be known as the solute.
How do you decant a solution?
Decanting can be used o separate a liquid from an insoluble solid. As the solid settles to the bottom of the container, the liquid can be carefully poured into another container leaving the solid (sediment) behind. Decanting can also be used to separate two immiscible liquids like oil and vinegar.
When water evaporates from a body of water what kind of sediment is left behind?
The sediment is a mixture of sand, soil, salts, detritus.
Which method could be used to obtain copper from a mixture of powdered copper and sodium chloride?
Wash the mixture with water and separate the solid from the liquid, for example, by filtration. The sodium chloride will dissolve in the wash water, while the copper is left behind.
A clear liquid in an open container is allowed to evaporate and after three days a solid is left in the container so was the clear liquid an element a compound or a mixture and how do you know?
mixture.
Can you separate a soluble from a liquid?
A soluble substance can be separated from a liquid by evaporation. Evaporate off the liquid and the solid is left behind.
Is liquid gas an element mixture or compound?
A compound is where the elemental components are chemically bonded at the molecular level and can only be separated with great effort (not evaporation). The liquid could have been a mixture (hard water for example; water with minerals, fluoride, calcium, salt whatever) and the dissolved minerals left behind when the liquid evaporated. However the liquid itself could be a compound (such as pure water) but the fact it left behind 'impurities' when it evaporated means it became a mixture or colloid when the impurities mixed into the liquid. So if the container was completely clean when the liquid was put in and there was no possibility of impurities being introduced from the air or other sources, it was a mixture before it evaporated.

Effect of the magnet bar on iron and sulfur mixture?
The iron particles will lift out of the mixture and stick to the magnet while the sulphur is left behind, effectively separating the mixture.
what other method of separating a liquid from a solid did you learn today other than filtration?
Methods of separating a solid and liquid rather than filtration. (a)When a solid and liquid are soluble,a method know as evaporation is used.When this mixture is heated,the liquid will evaporate and the solid will be left and obtained after evaporation. (b)When the mixture is insoluble,it is separated by use of decantation.The mixture is given some time to settle and the liquid is poured into another beaker and the the solid is left in the initial beaker.
What kind of casting method is resin casting?
Resin casting is done by use of a mold and a mixture made with a form of liquid synthetic resin. It is then poured or injected into the mold and left to sit until hardened.
Why do you have to filter the mixture?
To get rid of any residue that is left behind. Eg) a mixture of water and sand. You filter the sand because you only want the water.
How do you break the salt water mixture?
Let the water evaporate completely. The solid salt will be left behind.
When a liquid form a solution evoporate the?
When a liquid from a solution evaporates the solute will be left behind,e.g salt water,when the water evaporates only the salt will be left and that salt would be known as the solute.
