What is the difference between stoichiometric and non stoichiometric solids?
Non-stoichiometric compounds are chemical compounds with an elemental composition that cannot be represented by a ratio of well-defined natural numbers.Stoichiometric compounds are compounds in which atoms are combined in exact whole-number ratios.
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.
Why a sharp melting point could not be obtained always?
the melting point of pure substances is always being sharp. it means that the boiling point it have it will boil at that point not some up or down but on same temperature in other words we say that it has no impurities because of impurities it boiling point varies and it has many other components and boiling point of every component is different so that why the boiling point of impure compounds varies or it don t have exact value and the pure compounds have same elements combine together and every molecule boil at particular point so it has sharp melting point or exact point
When reactive elements combine they give off heat and what other substance?
Heat is energy, not a substance. When reactive elements combine they form more stable compounds. The exact substance formed depends on the elements. e.g. hydrogen and oxygen form water while sodium and chlorine form common table salt.
What is the exact molecular formula of honey?
Honey is a mixture of organic and some inorganic compounds, hence is not a pure substance and has no "one" or "exact" molecular formula. A typical honey breakdown of composition is: * Fructose: 38.5% * Glucose: 31.0% * Sucrose: 1.0% * Water: 17.0% * Other sugars: 9.0% (maltose, melezitose) * Ash: 0.17% * Other: 3.38% Fructose and glucose have the same empirical molecular formula: C6H12O6, just a different isomer of it. Sucrose is just a disaccharide of glucose and fructose with an α (alpha) 1,2 glycosidic linkage. The other compounds such as ash contain a large multitude of other compounds, making honey a very mixed batch of organic chemicals, we refer colloquially to as "honey".
What do compounds always contain exact ratios of?
elements
Do mixtures contain exact ratios of elements?
No, they do not.
What is the difference between stoichiometric and non stoichiometric solids?
Non-stoichiometric compounds are chemical compounds with an elemental composition that cannot be represented by a ratio of well-defined natural numbers.Stoichiometric compounds are compounds in which atoms are combined in exact whole-number ratios.
Does 'organic' mean that it contains hydrogen?
Organic compounds are most compounds that contain carbon. There are some carbon compounds, such as carbon dioxide, that are inorganic. Thus, a more specific definition is that an organic compound is a compound that contains carbon bonded to hydrogen, although the exact distinction may not always be this simple.
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 compound does not contain carbon and hydrogen together?
AnswerCompounds that do not contain carbon are inorganic; compounds that contain carbon are organic. Minerals are inorganic compounds.AnswerLoosely speaking, "inorganic".This is not exact scientific terminology, however, because there are inorganic compounds that DO contain carbon. Example: the global warming gas, carbon dioxide (CO2).Answerinorganic compounds.
When do two ratios form a proportion?
When both can multiply its comparisons to when both ratios share the exact same numbers.
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 is the relationship between element and compound?
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 is a list of Elements in a compound in exact ratios?
the emperical formula
Covalent compounds display which of these properties?
Covalent compounds are neutral. Covalent compounds share electrons. apex:)
What are the examples of synthetic media?
-The medium is chemically defined. This means that it only contains pure organic and pure inorganic compounds that are specified by an exact formula.The content varies little between sources. -Minimal media, for fungi, contain only a few essential compounds like salt and amino acids, other types of synthetic media are useful in research and cell culture when the exact nutritional needs of the test organisms are known.
