Carbon Dioxide and Carbon Monoxide. Bothe are made of carbon and oxygen, but different ratios of oxygen. Water and Hydrogen peroxide are another pair .
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
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 )
I believe...compounds are made up of two or more elements. Elements are made up of atoms.
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.
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.
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
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.
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.
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.
Elements combined in specific ratios form 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.
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.
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.
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 whole atoms of the same element combined to form compounds. Examples of the law of multiple proportions are CO and CO2.
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 )
