Diglycolamine has a molecular formula of C4H11NO2. This means it has 4 carbon atoms, 11 hydrogen atoms, a single nitrogen atom, and two oxygen atoms.
The answer is coded in the question itself: "Di" means 2 and "pent" means five; therefore the formula is P2O5.
A chemical formula is the number of atoms in a substance, and is the same as a molecular formula (provided the substance is a molecule - if not, it has no molecular formula). A structural formula shows how the atoms are linked, and there are different interpretations of this: eg C3H8O2 is the chemical formula of 1,2 propan di-ol, which is the same as the chemical formula of 1,1 propan di-ol the structural formula however is CH2OHCHOHCH3 for 1,2 propan di-ol and CH(OH)2CH2CH3 for 1,1 propan di-ol. A displayed formula shows all the bonds: ........H..OH...H.............O-H...H...H ........|....|.....|..................|....|.....| ....H-C.-.C.-.C.-.H.....H-O-C.-.C.-.C.-.H ........|....|.....|..................|....|.....| ....H-O...H....H.................H...H....H 1,2 propan di-ol........1,1 propan di-ol ---------------------------------- Some chemicals, such as table salt, have no molecule. Thus, they only have chemical formula but not molecular formula. The chemical formula of table salt is NaCl. There are other salts, such as Na2SO4, MgSO4, etc. (If you hear people saying "the salt molecule has the formula of NaCl...", believe me, they do not know what they are talking about.) Some compounds exist as molecules- discrete entities, such as water. This kind of compounds have molecular formula. Water's is H2O. Structural formula? Never heard of.
C2O5 Just look at the latin roots (di, pent >> 2, 5)
The answer to this question is coded in the name of the compound itself: "di" means 2 and "octa" means 8. Therefore, the formula is Si2N8.
Binary molecular compounds are composed of only two elements.Both are nonmetalsThey are not ions, so ionic charges are not used in formulas.They may combine in more than one way such as CO or CO2.A prefix is used in the name, such as mono- or di-An example of both the formula and the name of a binary molecular compound would be N2O4 or dinitrogen tetroxide. The prefixes are used in accordance to how many of one element is the formula, in this case two nitrogen and four oxygen.
You add one more amine into it !
Di-tert-butyl dicarbonate orC10H18O5
no, you are mistaking di-ethylene for di-ethyline , hope this helps
The answer is coded in the question itself: "Di" means 2 and "pent" means five; therefore the formula is P2O5.
H2N- (CH2)6-NH2
Any dioxide has two (= 'di-') oxygen atoms (= 'oxide') in its molecular formula. Examples: Carbon dioxide CO2 and Sulfur dioxide SO2
Above 7 being basic like any (di)amine group (-NH2)2 .Thiourea is an organosulfur compound of with the formula S=C(NH2)2 .
Diatomic elements consist of two atoms.The formula of these elements are always written with a subscript 2 in its symbol to indicate its molecular composition.examples: H2,O2.

It's empirical formula would be NH2. An empirical formula represents the ratio of the atoms in the compound, rather than the actual number. You can work this out by dividing by a common denominator (in this case, 2).
Oxidation value of N is minus two in H2N-NH2 and of H it is (as always) +1
