What is the name of a process by which water is broken down into hydrogen and oxygen?
It's an example of electrolysis. Not unwanted hair removal, but that does use the same process. Electrolysis is the process of breaking down compounds by running an electric current through them.
Who said the mass of an electron is about 12000 that of a hydrogen atom?
its not, its closer to about 1/1800 of a hydrogen atom, the English chemist john Dalton was the first person to discover relative atomic masses and use them properly.
What did early scientistis use the process of electrolysis for?
They used it to isolate the elements potassium, sodium, magnesium, calcium, strontium, and barium.
Why is John Dalton's atomic theory still mentioned in science?
Scientists use Dalton's atomic theory even though parts of it have been proven wrong as the basis of other discoveries. His theory about atomic elements being the same was wrong but has been used for a long time even to the discovery of isotopes.
Draw a labelled diagram of the apparatus you would use to show that a metal was a good conductor of electricity?
it can be demonstrated by electrolysis with copper anode and graphite Cu-2e=Cu_2+
Who used experiments to and scientific tools to study matter John Dalton Aristotle or Democritus?
John Dalton used experiments and scientific tools to study matter. Aristotle and Democritus did not use such methods in their studies of matter.
Who is credited with the first atomic theory based on expiramental evidence?
scientific method used in the development of atomic theory
What do we use electrolysis for in everyday life?
Any use of electrolysis in everyday life of an appartment.
How would you use testimonial in a sentence?
The statue of John Dalton in Manchester, England, is a testimonial to his scientific contributions.
What experiment did daltons use for his atomic theory?
dalton wasnt the one who experimented with gold, rutherford was the one who did the gold foil experiment.
How do you use electrolysis in a sentence?
The electrolysis process involves using an electric current to drive a non-spontaneous chemical reaction.
What type of energy does electrolysis use?
Electrolysis uses electrical energy to break down water or other substances into their constituent elements through the process of electrolysis.
The use of an electric current to produce a relatively permanent removal of undesired hair is known as?
electrolysis
Who is the scientist who first proposed the use of chemical symbols?
The scientist who first proposed the use of chemical symbols was John Dalton. His work in the early 19th century led to the development of the modern atomic theory and the use of symbols to represent elements in chemical formulas.
What did William Crookes use to test John Dalton's theory?
William Crookes used a cathode ray tube to test John Dalton's theory of the existence of atoms. By observing the behavior of cathode rays in the tube, Crookes provided evidence supporting the idea of discrete, indivisible particles.
Why did john Dalton use the Greek word for invisible to describe atoms?
John Dalton used the Greek word "atomos," meaning indivisible or invisible, to describe atoms because he believed that atoms were the smallest, indivisible particles that made up all matter. Dalton's atomic theory proposed that all elements are made up of tiny, indestructible particles called atoms, which combine in simple whole number ratios to form compounds. The use of the term "atomos" reflected Dalton's belief in the fundamental, invisible nature of these building blocks of matter.
How will you determine the purity of some metals?
use electrolysis
