Who discovered observe in the scientific method?
The concept of observation as a crucial step in the scientific method dates back to ancient Greek philosophers such as Aristotle and Plato. However, the modern scientific method, with its emphasis on systematic observation and experimentation, was further developed by scientists like Francis Bacon in the 17th century.
What factors determines the method used to extract a metal?
The method used to extract a metal is determined by factors such as the reactivity of the metal, its abundance in the Earth's crust, and the cost-effectiveness of the extraction process. Additionally, the physical and chemical properties of the ore from which the metal is extracted also play a role in selecting the extraction method.
What method do we use to extract more reactive metals such as aliminium?
Through electrolytic reduction.
How did the scientists method impact the work of scientists beginning in the 16th century?
it gave scientists a way to repeat others' work to make sure it was correct
Hall discovered how to extract aluminum by?
Hall discovered how to extract aluminum by using the electrolysis process in 1886. This process involves passing an electric current through a molten mixture of aluminum oxide and cryolite, resulting in the separation of aluminum from oxygen. This method revolutionized the production of aluminum and is still used today.
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.
How can you extract the oxygen from hydrogen peroxide?
To extract oxygen from hydrogen peroxide, you can simply heat it. Hydrogen peroxide decomposes into water and oxygen when heated, and the oxygen gas can be collected. This is a common method used in laboratories to obtain oxygen gas.
Discoverer of deuterium?
Deuterium was discovered in 1931 by Harold Urey, a chemist at Columbia University. Urey successfully separated deuterium from hydrogen by using a method called fractional distillation. His discovery of deuterium revolutionized the field of nuclear chemistry.
Learning by the trial and error method was discovered by?
Learning by "trial and error method" was discovered by - THORNDIKE
How can you extract hydrogen?
Hydrogen can be extracted through various methods, with the most common being steam methane reforming (SMR), where natural gas is reacted with steam to produce hydrogen and carbon dioxide. Another method is electrolysis, where water is split into hydrogen and oxygen using electricity, ideally from renewable sources for a greener approach. Other techniques include gasification of biomass and thermochemical water splitting, but these are less widely used. Each method varies in efficiency, cost, and environmental impact.
How is hydrogen gathered?
we extract it from fossil fuelsHydrogen is obtained by the electrolysis of water.
Scientists usually design experiments?
Why is it important for scientists to use the scientific method
Why was a dutch hamburger pattie in the news last week?
A group of scientists have discovered a way to grow organs in a laboratory. They think that they can use this method to make test tube hamburgers in the future.
How did the scientific method change the way scientific came to a conclusion?
It didn't because before the scientific method there were no scientists. Scientists are professionals that employ the scientific method to do their work.

Describe the method of purification of copper?
The method used to extract Cu from its ore depends on the nature of the ore.
What is a antonym for the word scientific method?
a non method used by scientists
