16 + 20 + 14 = 50 = 12 + 14 +14 + 10
That's the beginning of the Fibonacci series.
To find the mean (or average) you first add up the numbers you have. NOTHING 1.88

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, Pb(CrO4)2 is not a molecular compound. It is an ionic compound composed of lead(II) cations (Pb2+) and chromate anions (CrO4)2-.
The chemical symbol for chromate is CrO4^2-.
The symbol for a chromate ion is CrO4^2-.
The formula of the chromate ion is CrO4^2-.
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.
The chemical formula for Barium ion (Ba2+) is simply Ba2+ and the chemical formula for Nitrate ion (NO3-) is NO3−. To represent the compound formed by Barium ion and Nitrate ion, write Ba(NO3)2.
