Do elements that combine in changing ratios form mixtures?
No, compounds are formed.
What forms a compound?
Atoms of elements combine in fixed ratios will form compounds.
Did Dalton's atomic theory state that atoms of different elements combine in simple whole-number ratios can form compounds?
John Dalton, the father of modern chemistry, said that atoms combine in simple whole-number rations to form compounds.
Can two completely different compounds contain identical elements?
No. The chemical formulas for the two compounds would be different as the ratios were different. For example there are three different oxides of iron which obviously contain the same two elements but these are in different ratios:- FeO Fe3O4 Fe2O3
Do elements always combine in specific ratios?
The Law of Definite Proportions says that a given chemical compound always contains the same proportion by mass of its constituent elements. This is NOT the same as saying that elements always combine in a specific ratio, because they can combine in different ratios in different compounds. An example of this might be copper oxide which can be CuO or Cu2O, showing a different ratio of copper to oxygen. So, the answer to the question, as asked, is no, elements do not always combine in specific ratios.
Do elements that combine in changing ratios form mixtures?
No, compounds are formed.
What do you get with changing ratios that combine in elements?
In this mode different compounds are obtained.

What do compounds always contain exact ratios of?
elements

Which elements proved difficult for mendeleev to add to his table because they were found to combine in various ratios with other elements?
Copper and magnesium are elements that were difficult for Mendeleev to add to his table because they were found to combine in various ratios with other elements.copper and manganese

What a compound is and how compounds are formed?
Compounds are made by elements bonding together. They are represented by the chemical formula. The chemical formula shows the elements and their ratios in the compound.
What is matter made of elements combined in changing ratios?
You think probable compounds.
What type of matter is made of elements in a specific ratio that is always the same?
Elements combined in specific ratios form compounds.
Daltons atomic theory stated that atoms?
atoms are indivisible,tiniest particles of matter. they combine in simple whole no ratios to form elements or compounds. they can neither be created, nor destroyed.
