Answer:
Explanation:
There are many compounds that are produced from Nickel.
Molar mass of Ni = 58.7g
So for 0.235g Ni, there are 0.004M.
By conservation of mass, the compound produced will contain 0.04M of Ni.
Out of the choices given, the one that describes a substance whose atoms all have the same number of protons are an element. The correct answer will be B.
Answer:b

Answer:
Explanation:
Use the dilution equation: M1V1 = M2V2
M1 = 6.0 M
V1 = 0.025 L
M2 = ?
V2 = 1.75 L
(6.0 M)(0.025 L) = M2(1.75 L)
Solve for M2 --> M2 = 0.086 M HCl
