How can the existence of atoms help to explain the law of definite proportions?
If the mass proportions of the original substances do not equal these definite proportions, there will something of one of the original substances be left over. Note that this is special, it could as well have turned out to be possible for substances to combine in any proportion. So we find the law of definite proportions. Now we should be baffled and wonder how on Earth could that be so? And then we could think of substances being made of small particles (atoms) or groups of such particles (molecules) to explain the laws of nature that we found. So the laws of definite proportions and multiple proportions are (partially) proof for the existence of atoms which combine into molecules. The laws are the real thing and atoms and molecules and their chemical formulas are the ideas we make to understand the laws.
What is the ratio of elements in a compound?
The ratio of elements in a compound is determined by the number of atoms of each element present in the compound. This ratio is represented by the chemical formula of the compound, showing the types and numbers of atoms involved in the chemical bonding.
What consisits of 2 or more atoms joined in a definite ratio?
covalent bonds a bond (any type of bond, but JUST the word bond!)
Is a compound a chemical combination of atoms whose proportions do not vary?
Yes, a compound is a substance made up of two or more different types of atoms chemically bonded together in fixed proportions. The ratio of atoms in a compound remains constant regardless of the amount of the compound present.
Compounds consists of atoma of two or more ...combined together in ..proportions?
Compounds consist of atoms of two or more elements.
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.
What term describes a substance formed by the combination of two ore more elements in definite proportions?
A compound is a substance formed by the combination of two or more elements in definite proportions. Each compound has a specific chemical formula that indicates the types of atoms present and the ratio in which they are combined.
The ratio in which atoms are blended together in compounds is shown by an?
By the law of definite proportions.

What are two or more different atoms are combined in definite proportion?
A simple definition is: a chemical compond has the elemental components in a fixed ratio.

How does the law of definite proportions explain the fact that although water and hydrogen peroxide consist of the same elements have different properties?
First find out what the law of definite proportions is. Then explain the fact that water and hydrogen peroxide consist of the same elements. Then find out if they have different or the same properties.
What is the ratio of elements in a compound?
The ratio of elements in a compound is determined by the number of atoms of each element present in the compound. This ratio is represented by the chemical formula of the compound, showing the types and numbers of atoms involved in the chemical bonding.
What edvidence convinced Dalton that elements must be made of individual particles called atoms?
He deduced that from the law of definite proportions.
What law does this statement agree with If it doesn't have exactly have one oxygen atom and two hydrogen atoms its not water?
the law of definite proportions
What is the experiment that john Dalton carried out that led to the law of definite proportions?
John Dalton wrote four essays called "Experimental Essays" based on his "Atomic Theory", which explained matter as consisting of discrete atoms, that there was one type of atom for each element, and that the compounds were made of combinations of different types of atoms in fixed proportions.
What consisits of 2 or more atoms joined in a definite ratio?
covalent bonds a bond (any type of bond, but JUST the word bond!)
