Why couldn't scientists in 1800 extract aluminium from alumina?

In 1800, scientists could not extract aluminum from alumina because the process to extract aluminum from alumina requires high temperatures and the availability of electricity, which were not readily accessible or understood at that time. It wasn't until the late 19th century, with the development of the Hall-Héroult process, that a commercially viable method for extracting aluminum from alumina was discovered.

What could happen if a baby drink almond extract?

If a baby consumes almond extract, there are potential risks, especially if the extract contains bitter almonds, which contain cyanide and can be toxic. Even if the extract is made from sweet almonds, it may contain high levels of alcohol or other additives that could be harmful to infants. Additionally, almond extract can trigger allergic reactions in susceptible individuals. It's always best to consult a pediatrician if a baby ingests anything that could be potentially harmful.

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.


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 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.
