The oxidation number of B in B4O7 is +3. This can be determined by assigning oxygen an oxidation number of -2, then setting up an equation to solve for the oxidation number of B.
The compound name for K2Cr2O7 is potassium dichromate.
The chemical name O7 does not correspond to a specific compound. In chemical nomenclature, the symbol O represents oxygen, but the number 7 on its own does not provide enough information to identify a particular molecule. More details, such as the elements involved and their proportions, are needed to determine the specific compound.
(NH4)2 Cr2 O7 --------> N2 + 4H2O + Cr2 O3
Since oxygen atoms can only accept two electrons, the balance of charges for the overall neutral molecule suggests that the two chromium atoms must each have donated half of the electrons to the oxygen atoms. Therefore, the total number of electrons required for all three oxygen atoms to reach a noble gas configuration is 3 atoms*2 electrons/atom=6 electrons Dividing this up between the two chromium atoms: 6 electrons/2 atoms=3 electrons/atom Therefore, each chromium atom bears a positive charge (since it donated electrons) of 3+.
Methyl orange is synthesized by reaction of sulfanilic acid, sodium nitrite, and dimethylaniline. First, sulfanilic acid is dissolved in dilute aqueous acid. Sodium nitrite is added to produce a disowning salt .Chemical formula of Methyl Orange: C14H14N3NaO3S
