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
Answer:
Lewis definition
Explanation:
Lewis defintion considers electron transfer instead of proton transfer to define acids and bases. A Lewis acid accepts an electron pair while a Lewis base donates an electron pair. Since this definition refers to electrons only, virtually any compound can be a Lewis acid.
