When baking a cake what does it mean when it says to fold one mixture into another mixture?
When baking, folding is a method used to incorporate more air into the mixtures. In order to fold, you need a spatula or a spoon. Carefully pour mixture A into mixture B a little at a time. Take the spatula, scrape the bottom of the bowl, and take mixture B and "fold" it over the other mixture. Do not simply stir, as that would dispel the air and make the cake heavy. Continue to scrape the bottom of the bowl and flop the mixture A over mixture B until well combined! So basically, you are literally folding the mixture!
When is decanration used to separate a mixture?
Decantation is used to separate a mixture when one component is more dense or insoluble in the mixture. By allowing the mixture to stand undisturbed, the heavier or insoluble component settles to the bottom, allowing the clear liquid to be poured off.
Can the term solution be used to identify a mixture that has the same composition throughout?
The term solution can be used to identify a mixture that has the same composition throughout.
What is Earthly deposit of clay and lime mixture called?
A deposit of clay and lime mixture on Earth is called marl. Marl is formed from the accumulation of clay and calcium carbonate-based materials over time, often found in sedimentary rock layers. It is commonly used in agriculture and construction due to its nutrient-rich and binding properties.
Why rich mixture used during starting of engine?
There is no Oil lubricating your engine at a cold start up, so a rich mixture is used to try eliminating any scouring on your (internal) engine components.
What is full rich position of mixture control in aeroplane?
The mixture control of a piston powered engine enables you to vary the amount of fuel being used in your specific fuel/air mixture. At higher power settings and lower altitudes, more fuel is needed in the mixture while at higher altitudes and lower cruise power settings, less fuel can be added to the mixture thus conserving on the amount of fuel used during a flight.
Which manufacturer used only three colors in their paint?
they are used to take mixture from a colour
What thermostat is used in a 1991 Honda CRX?
In todays car a 195 degree thermostat is used. Any colder and the computer will keep the fuel mixture rich.
What is a mixture of decayed matter?

Why do you use ethanol after chloroform and isoamylalcohol mixture and isopropanol during genomic DNA isolation?
Ethanol is used after the chloroform and isoamylalcohol mixture to precipitate DNA from the solution. Isopropanol is used during genomic DNA isolation to further facilitate the precipitation of DNA, ensuring a higher yield and purity of DNA in the final step.
What can be used to separate parts of a mixture?
If the mixture is a mixture of solids and if one of constituent is a ferromagnetic substance, a magnet can be used to separate the magnetic and non-magnetic substances. If one of the constituent is a sublimate, sublimation can be used. If the mixture is a mixture of solids and liquids, decantation, filtration and distillation can be used. If the mixture is a mixture of liquids, fractional distillation can be used to separate the different constituents taking advantage of the difference in boiling points of the different constituents.
