What is the chemical reaction when aluminium is added to water?
Aluminium hydroxide could be formed
Why do you use aluminium to make airplane?
Aluminium is good for airplanes because it is very hard, it is insoluble in water and it could resist corrosion.
How can you use extract in a sentence?
As a noun: I always use pure vanilla extract, never imitation vanilla flavoring.As a verb: They could not extract him from the wreck without cutting the car away with a 'jaws of life'.
Can scientists predict a meteor shower?
yes they could.
Why is honesty important with scientists?
Scientists can tell whether something is right or wrong in an experiment. If scientists were not honest, then the results of their experiments could be skewed to match their hypothesis or to please others. All scientists must do this in order to maintain the best unbiased results.

What would one do with catnip extract?
There are many things one could do with catnip extract. One would be able to give the extract to their cat or place the extract on one of the cat's toys.

Can you use almond extract instead of vanilla extract?
You could use vanilla extract, but the taste would be different. you are bettere off going with almond instead
How many grams of copper could you get from 30 grams of aluminum?
None, as pure Aluminium is an element which contains only atoms of Aluminium and nothing else.
Is molasses like vanilla extract?
No. Vanilla Extract is for flavoring . Molasses is like an ingredient to make brown sugar. :Dglad I could help

Which metal could you wrap a baked potato in off the periodic table?
Aluminium (foil)
Why didn't the Romans use aluminum as weapons?
The Romans did not use aluminium for weapons because they did not know it was a metal. Even if they had known, aluminium they would not have used it to make weapoun because it is too soft this.Aluminium was identified as a metal only in 1808. This is because aluminium never occurs in metallic or natural forms in nature. The main source of aluminium is bauxite, a heterogeneous material which ranges from clay through to soft rock and can be white, pink, yellow, red or brown, or various combinations of these colours. It is composed mainly of one or more hydroxides of aluminium (50-60 %) and various mixtures of silicon, oxides of iron, titanium, and varying small percentages of clay and other silicates.Bauxite first appeared in history around the fifth century B.C. when the Egyptians and the Greeks used it as an astringent for dressing wounds and to fix dyes in textiles. This use as such continued until the Middle Ages. By the thirteenth century, some purification of aluminium was occurring and by the seventeenth century, it was being separated from the clays in which it was found. At the beginning of the eighteenth century, there was a suspicion that alumina had a metallic base which could probably be isolated. This was confirmed by the Antoine-Laurent de Lavoisier in 1787.Producing aluminium is not easy. In 1808, Sir Humphrey Davy, attempted to isolate the metal using electrolysis, but managed only to produce aluminium alloyed with iron. The first small amount of aluminium were created in 1825 Hans Christian Oersted, and in 1827 by Friedrich Wöhler. The same time Robert Wilhelm von Bunsen, demonstrated that aluminium could be purified using electrolysis. The basis for the modern aluminium industry was established in 1886.
How do you make acid from a rose petal?
I and my scientific research group, discovered that we must extract the rose petal first, to gain the acid. We could extract it with boiling the rose petals with a few mililiters of water in a beaker glass. Try to extract it with spirtus and tripod, so that the extract will be pure and got the maximum quality. After we extract it, we could test it with the litmus paper. I'm sorry if the answer didn't fulfill your need. And sorry for the fail Engish.
Is aluminum a secondary or primary source of light?
Aluminium is not normally a source of light. I suppose if you made a large mirror out of it you could turn that into a secondary source.
How do you make aluminum phosphide tablets?
Aluminum is made from a clay called bauxite, which contains aluminum oxide, or alumina. The bauxite is then refined to separate the pure alumina out. The alumina is then electrified to produce liquid aluminum which is cast into aluminum ingots.
