Is ratio of atoms is always the same in a compound?
Generally yes (the law of definite proportions); as exceptions - nonstoichiometric compounds.
How are compounds diffident from mixtures?
Compounds are composed of atoms of different elements chemically bonded in definite proportions. The components of mixtures are not chemically combined and they do not have definite proportions.
Which of Dalton's four principles support law of definite proportions?
Dalton\'s principle of compounds supports the law of definite proportions.
A combination of two or more elements in definite proportions?
compounds
What is the name for two elements that are cheically combined in definite proportions?
Compounds.
The ratio in which atoms are blended together in compounds is shown by an?
By the law of definite proportions.
State the law of definite proportions?
The law of definite proportions states that all chemical compounds have constant proportions of their components.
What you mean by nonstoichiometry?
The chemical composition of nonstoichiometric compounds do not respect the law of definite proportions.
What are non-stoichiometric defects?
Non stoichiometric compounds do not match to law of definite proportions.
What factors affect the ratio when substance combine to form compounds?
These are the laws of multiple proportions, definite proportions and mass conservation.
What are pure compounds?
A substance made from two or more elements in definite proportions. eg NaCl
Is it true that a chemical has a definite composition?
Yes, after the Law of definite proportions; but now it is clear that this law is not applicable to all known chemical compounds.
