The compound name for K2Cr2O7 is potassium dichromate.
(NH4)2 Cr2 O7 --------> N2 + 4H2O + Cr2 O3
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.
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.
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
The molecular formula is C6H8O7 but that does not give you the shape of the molecule it only gives the numbers of different atoms involved.Citric acid is in citrus fruits, and often used in fruit-tast sodas.Structural formula: (HOOC)-CH2-C(OH)(COOH)-CH2-(COOH)Name: Citric acid (plant biology, food)trivial name: TCA, or tricarboxylic acid (biochemistry)official name: 2-hydroxypropane-1,2,3-tricarboxylic acid (IUPAC)or 3-carboxy-3-hydroxypentanedioic acid (an older chemical name)I would suggest checking to check the link in 'Related links' for more information.

Percent by (basic) mass is easy... K2 = 39 x 2 = 78 Cr2 = 52 x 2 = 104 O7 = 16 x 7 = 112 % by mass = 112/(78+104+112) = 56/142 = 29.9465% If you're looking for a more complex/precise derivative that includes the probabalistic mass of the electrons, etc. then it becomes much more complicated. -D

o7 plate
An O7 ion is a hypothetical charged particle that would consist of seven oxygen atoms with a charge of -7. This ion is not commonly found in nature but may be formed under extreme experimental conditions in a laboratory setting.
