What else can I help you with?
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
Can all elements form compounds?
Compounds are combinations of elements. They are different from molecules in the fact that Compounds cannot be a combination of the same element ( O2 ) instead compounds are combinations of different elements ( CO2 )
What is the relationship between atoms elements and compounds?
I believe...compounds are made up of two or more elements. Elements are made up of atoms.
What Elements combine in fixed mass ratios to form compounds This must mean that elements?
In chemical compounds, elements combine in fixed ratios by mass to form stable, distinct substances. This observation is summarized in the law of definite proportions, which states that a compound is always composed of the same elements in the same proportions by mass. This principle demonstrates the predictable and reproducible nature of chemical reactions.
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.
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 compounds usually have variable ratios where as mixtures usually have fixed ratios?
No, its the opposite. Compounds have fixed ratios, think of H20, while mixtures can vary. You can make many types of mixtures out of the same things. Because of bonding compounds have fixed ratios.
Do the atoms in a mixture have a set ratio?
Atoms can interact in different manners. Compounds can have the same ratios of atoms combined in different ways producing different properties (cis and trans forms of compounds come to mind). Additionally, many compounds consist of the same elements but in different ratios. Compare Carbon dioxide, a inert waste product of respiration, to carbon monoxide, a gas deadly to humans. Both use carbon and oxygen, but CO2 has an extra oxygen molecule, greatly changing its properties. So in short, no. Atoms can combine in multiple ratios, and even compounds of equal ratios can come together in different manners to produce different compounds.
Different compounds can be formed from similar elements?
Yes. And this might blow your mind but different compounds can even be formed from the same number and type of elements. Isomers! Example: Theobromine= vasodilator Theophylline= anti-inflammatory Same amount and type of elements, but arranged differently makes a completely different compound.
What type of matter is made of elements in a specific ratio that is always the same?
Elements combined in specific ratios form compounds.
What the relationship between the elements and the compounds?
Atoms make up all matter. An element has atoms that are all the same. Compounds are made of different kinds of atoms combined chemically in exact whole number ratios.
What parts of daltons atomic theory is illustrated by 2 parts of hydrogen and oxygen forming water?
Dalton's atomic theory is illustrated by the combination of hydrogen and oxygen to form water in two ways: through the law of definite proportions, which states that compounds contain elements in specific ratios by mass, and through the law of multiple proportions, which states that different compounds can be formed by combining the same elements in different ratios.
How can two coumpounds made from the same element be so different?
Because the proportions of the elements are different in the different compounds. They may contain the same elements, but the different proportions make them different compounds with different properties.
What is meant by the law of constant composition for compounds?
The law of constant composition for compounds is a law in chemistry according to which any given compound always contains the same component elements in the same ratios, by mass. The ratios do not depend on where the compound comes from or the way in which it was produced.
The law of multiple proportions can be partly explained by the idea that?
The law of multiple proportions can be partly explained by the idea that whole atoms of the same element combined to form compounds. Examples of the law of multiple proportions are CO and CO2.
Can all elements form compounds?
Compounds are combinations of elements. They are different from molecules in the fact that Compounds cannot be a combination of the same element ( O2 ) instead compounds are combinations of different elements ( CO2 )
What is the relationship between atoms elements and compounds?
