Answer:
Total concentration of ions present in the final solution is 0.0726 M.
Explanation:
Mass of silver nitrate = 54.0 g
Moles of silver nitrate =
Volume of the solution made = V = 350.0 mL = 0.350 L
After dilution of 10.00 mL 0.9227 M solution.
Concentration of silver nitrate after dilution = 0.0363 M
Total concentration of ions present in the final solution:
Answer:
Explanation:
Mean of observation of A = 87.63
Mean of observation of B = 87.06
Mean of observation of C=87.76
So reading of B is closest to true volume hence his result is most accurate. Reading of C is least accurate.
As far as precision of measurement is concerned, it depends upon measuring instrument. From the reading it appears that the measuring instrument is the same because the no of significant figure of the reading is same ( three) . Hence their reading are equally precise.
The answer is :
Nickel II carbonate octahydrate
The explanation:
-when Ni is the symbol of Nickel.
and CO3 is the symbol of carbonate group.
and both have 2 valence so, it will be write 2:2 = 1:1 → NiCO3 named Nickel caronae.
and any compound contain H2O will be named Hydrate and here we have 8 H2O so, i will e named octa (because of his 8 ) octahydrate
so, the compound will be Nickel II carbonate octahydrate
