24= y2k* - 2x H202 grams in mass
Answer:
0.925 moles of Nickel (II) chloride
Explanation:
Now, we know that the number of moles in a solution is given by;
n=CV
n= number of moles
C= molar concentration of solution = 0.925 M
V= volume of solution= 1.0 L
So having known all the parameters except the unknown (number of moles of Nickel (II) chloride) we can now proceed to find the unknown.
n= 0.925M ×1.0L
n= 0.925 moles of Nickel (II) chloride
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
It’s number one because you add all of them together
