find atomicty of water
Answers
Answer:
Explanation:
The atomicity of a substance is the number of atoms in each molecule of the substance.
Two molecules of hydrogen and one molecule of oxygen form one molecule of water.
Each molecule of hydrogen has two atoms of hydrogen. Therefore the atomicity of hydrogen is two. Similarly each molecule of oxygen consists of two atoms of oxygen. The atomicity of oxygen is two.
One molecule of water contains two atoms of hydrogen and one atom of oxygen, so the atomicity of water is three.
Answer:
key terms ... (I) atomic theory's (ii) what I atom?
Explanation:
(i). after the discovery of above two laws of chemical combination, the next problem faced by the the scientist was to give appropriate explanation of these laws .
this led a british chemist, John Dalton yo put forward the basic theory about the nature of matter in ,1808. this theory is known as " Dalton 's theory's. this theory is based on concept of divisibility of matter , which was proposed by the ancient philosophers.
(ii). an atom may be defined as the smallest particle of an element which may or may not be capable of free exitence. however., it is the smallest particle that takes part in a chemical reaction..
(iii). for example- atoms of noble gases, that is, helium, neon, argon, Krypton, and xenon are unreactive and thus , exist in the free state. however, atoms of hydrogen, oxygen, nitrogen, etc., are highly reactive and do not exist in the free state.....
I hope it's help you....
