What is the compound Cd3N2?
It's cadmium nitride, not cadmium binitride because the prefix "bi" is not used in ionic compounds such as these, only in molecular compounds.
What does the prefix eco mean?
The prefix eco- means environment or habitat. It is often used in nonce compounds.
What prefix means water?
Aqua. Hydro. As in aquifer or hydro-electric.
What does the prefix in a chemical formula mean?
Different things for different prefixes. Meth, eth, prop, etc. are prefixes in organic chemistry that tell you that there are 1, 2, 3, etc. carbon atoms in a compound. Other prefixes mean other things. But you need to learn the rules for naming compounds, because there are exceptions. CO has just one carbon, but its name has nothing to do with the meth prefix. It is called carbon monoxide.
How do you write the molecular formula for n-pentane?
The prefix "n-" indicates a straight carbon chain and the particle "pent" indicates five carbon atoms. One way of writing the formula is: H3C-CH2-CH2-CH2-CH3
What is the relationship between prefixes and molecular compounds?
the relationship between prefixes and molecular compounds is that, prefix are used to name molecular compounds.
What is the compound Cd3N2?
It's cadmium nitride, not cadmium binitride because the prefix "bi" is not used in ionic compounds such as these, only in molecular compounds.
What is the meaing of carbon dioxide?
According to the rules of nomenclature for molecular compounds, "carbon" means 1 carbon (the absence of a prefix in the first element of a molecular compound means there's just one) and "dioxide" means 2 (the prefix di- means 2.) If, by chance, the second element of a molecular compounds has 1, then you do use the prefix mono-, for example, carbon monoxide. However, a molecular compound never starts with mono-. If there's just one, you omit the prefix on the first of the two elements. So, carbon dioxide means 1 carbon, 2 oxygens, so CO2.
What are molecule compounds?
Naming Binary Molecular CompoundsBinary molecular compounds are composed of only two elements. Examples are H2O, NO, SF6 etc. . Naming these binary compounds is a little bit more involved than naming salts. Why is this so? Molecular compounds are more difficult to name because the atoms combine through covalent and not ionic bonds. Therefore we cannot use the electrical neutrality rule for these compounds. Most molecular compounds are made from nonmetals. Sometimes these compounds have generic or common names (e.g., H2O is "water") and they also have systematic names (e.g., H2O, dihydrogen monoxide). The common name must be memorized. The systematic name is more complicated but it has the advantage that the formula of the compound can be deduced from the name. Simple binary compounds consist of only a few atoms. Systematic naming of these compounds follow the rules: * The elements , except for H, are are written in order of increasing group number (e.g., NO not ON) * The number of atoms of a given type is designated by a prefix such as di- , tri-, tetra- etc. (The exception to this rule is for the first atom: if the first atom is "mono" then no prefix for it is given.) (e.g., NO is nitrogen monoxide not mononitrogen monoxide)
What method is used to distinguish between different molecular compounds that contain the same element?
They use subscripts in the chemical formula. Example H2O indicates that there are two hydrogens.
Where on the periodic table will you find the two elements in a binary molecular compound?
There are millions of different chemical compounds and they are made up of many diffent things. Not even necessaraly made of only two elements.
What does the prefix eco mean?
The prefix eco- means environment or habitat. It is often used in nonce compounds.
What words begin with the prefix tetra?
My names of chemical compounds begin with the prefix tetra, such as Carbon tetrachloride and Tetrahydrocanabinol.
When is a prefix not used in front of the name of an element?
No prefix is used if it is an ionic compound. If it is a binary molecular compound, the prefix mono- is not used in front of the name of the first element. For example, the ionic compound Na2O is sodium oxide, not disodium monoxide, and the molecular compound CO2 is carbon dioxide, not monocarbon dioxide.
Why does sulphur plus oxygen use the term dioxide for oxygen but magnesium plus oxygen uses the term oxide. Is it because Mg is a metal?
I answered this question. It is indeed because Mg is a metal. Ionic compounds (those with a metal) do not get a prefix, molecular compounds (those without a metal) do.
Which of the following correctly shows a prefix used in naming binary molecular compounds with its corresponding number?
Binary molecular compounds are named according to the number of atoms in the compound. Each part gets its own prefix.For example:H2O= Dihydrogen monoxideMgO= Magnesium monoxideBr2O7 = Dibromine heptoxideCaO= Calcium monoxideBr4Cl8 = Tetrabromine octachloride
What is the prefix of praised?
As written, there is no prefix as part of the word "praised".
