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

Ba2(SO4)2
2 dots
CrO4-2
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
oo
Charge of CrO4 is -2
At first dissolution reactionBa(OH)2(s) --> Ba2+(aq) + 2OH-(aq)Then precipitation reaction Ba2+(aq) + [SO4 2-](s) --> BaSO4(s)
lithium dichromate-LiCrO4 Li-lithium+1 chromate- CrO4-2
56-2=54 Your answer is 54. ~JM Chem 130 2012~
CrO4-2
I believe that would be Barium nitrate or Ba(NO3)2
That is, Ag2CrO4 Ag + and CrO4 2- come together to form Ag2CrO4 Silver chromate --------------------
