To find the mean (or average) you first add up the numbers you have. NOTHING 1.88
That's the beginning of the Fibonacci series.

CrO4-2
The reaction between SO42- and Ba2+ forms BaSO4. The chemical formula is BaSO4.
The white precipitate formed in the reaction between BaCl2 and K2CrO4 is BaCrO4 (barium chromate). This precipitate forms because Ba2+ ions from BaCl2 react with CrO4^2- ions from K2CrO4 to produce an insoluble compound that falls out of solution.
No. It is an ionic compound composed of the lead IV cation (Pb4+) and the chromate anion (CrO4)2-.Pb4+ + 2(CrO4)2- --> Pb(CrO4)2
The chemical symbol for chromate is CrO4^2-.
The symbol for a chromate ion is CrO4^2-.
Formula: CrO4-2
The oxidation state of Ba2 is 2.
56-2=54 Your answer is 54. ~JM Chem 130 2012~
The ion for K2CrO4 is the chromate ion, which has a chemical formula of CrO4^2-.
The formula for a chromate ion is CrO4-2, and its charge is -2.
