What does the chemical name of a compound tell us?
A compound is a substance made up of a definite proportion of two or more elements. A chemical formula tells us the number of atoms of each element in a compound. It contains the symbols of the atoms of the elements present in the compound as well as how many there are for each element in the form of subscripts.
What is the formula dinitrogen?
For example, if the current date is 1/1/2012, this formula returns 1/6/2012. Returns the number of days between the current date and 1/1/2030. Note that cell A4 must be formatted as General or Number for the result to display correctly. Returns the current day of the month (1 – 31).
What substance do molecules have the strongest attraction to one another?
Stack #171756
| Question | Answer |
|---|---|
| In which substance do the molecules have the strongest attraction to one another? | sugar, a solid |
| Often atoms join so that each atom will have | an outermost energy level that is full of electrons |
| In a metallic bond, the nucleus of one atom is attracted by the nearby atom’s | electrons |
What is the anion formed from an oxygen atom called?
Forming negative ions
| Atom name | Ion name |
|---|---|
| Oxygen | Oxide |
| Fluorine | Fluoride |
| Bromine | Bromide |
| Iodine | Iodide |
What does the coefficient in a formula tell us?
Coefficients are used in all chemical equations to show the relative amounts of each substance present. This amount can represent either the relative number of molecules, or the relative number of moles (described below). If no coefficient is shown, a one (1) is assumed.
What ionic compound is Fe2O3?
Iron(III) oxide
Iron(III) oxide or ferric oxide is the inorganic compound with the formula Fe2O3. It is one of the three main oxides of iron, the other two being iron(II) oxide (FeO) the rarer form, and iron(II,III) oxide (Fe3O4) which naturally as magnetite.
What do intermolecular forces determine?
Intermolecular forces are much weaker than the intramolecular forces of attraction but are important because they determine the physical properties of molecules like their boiling point, melting point, density, and enthalpies of fusion and vaporization.
How is ionic bond formed?
ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. Such a bond forms when the valence (outermost) electrons of one atom are transferred permanently to another atom.
What is the coefficient of a compound?
The coefficient in a chemical formula is the number immediately preceding the compound. It appears full size, never as a subscript or superscript.
Is dinitrogen monoxide a compound or molecule?
Nitrous oxide, also known as dinitrogen oxide or dinitrogen monoxide, is a chemical compound with chemical formula N2O. It is commonly known as laughing gas due to the exhilarating effects of inhaling it.
What are the uses of dinitrogen pentoxide?
Uses of Dinitrogen Pentoxide – N 2 O 5 Used as a robust oxidizer in high-fuel rockets. Used in solvents that are not based on water, so that molecules that are very sensitive to water can be easily nitrated. Used as a nitrating agent in modern synthetic organic chemistry.
What is dinitrogen trioxide used for?
Dinitrogen trioxide is used as a special purpose fuels due to its highly combustible nature. The chemical only supports combustion and doesn’t actually burn. It is more often used as an oxidizing agent in combination with other chemical compounds.
What is the common name for dinitrogen monoxide?
Nitrous oxide (N2O), also called dinitrogen monoxide, laughing gas, or nitrous, one of several oxides of nitrogen, a colourless gas with pleasant, sweetish odour and taste, which when inhaled produces insensibility to pain preceded by mild hysteria, sometimes laughter.
