1 million = 10 lakhs (in Indian rupees) Then, 31.6 millions = 3 cr 16 lakhs
write the number that is 100 less
You write a number, not wright! It would be written as 75% of [the number].
To write 7 as an ordinal number, you would write it as "seventh."

The oxidation number for Cr in Cr2O7^2- is +6.
The change in oxidation number of Cr depends on the specific reaction or compound involved. For example, in the reaction from Cr(III) to Cr(VI), the oxidation number of Cr changes from +3 to +6, indicating an increase in oxidation state.
The atomic number of Cr, which stands for chromium, is 24.
+3 for Cr and -2 for O
+2 for Ca, +6 for Cr, -2 for each O

The oxidation number of Cr in CrBr is +3. Since Br has an oxidation number of -1 and there is only one Br atom in the compound, the oxidation number of Cr must be +3 to balance the charges to zero.
The oxidation number of Cr in Cr2O7^2- is +6. This is because the overall charge of the dichromate ion is 2-, and each oxygen atom has an oxidation number of -2. By setting up and solving an equation representing the total charge of the ion, we can determine the oxidation number of Cr.
The oxidation number of Cr in MgCrO4 is +6. This is because oxygen is typically assigned an oxidation number of -2, and the overall charge of the compound is 0, so the oxidation number of magnesium (+2) and oxygen (-2) must be balanced by the oxidation number of Cr (+6).
