Answer:
A strong base produces more ions in solution than a weak base.
Explanation:
Answer:
is formed and it has three unpaired electrons.
Explanation:
Blue
reacts with water to produce pink colored
complex.
In this complex,
ion forms an octahedral complex with six
ligands.
As
is a weak field ligand therefore
ion remains in low spin state.
Hence electronic configuration of
ion in this octahedral geometry is
with total three unpaired electrons.
Answer:
Approx. 4⋅g.
Explanation:
Moles of sulfuric acid =10.0⋅g98.08⋅g⋅mol−1=0.102⋅mol.
Now we have the molar quantity of sulfuric acid that react; we also have the stoichiometric equation that shows the molar equivalence of sulfuric acid, and lithium hydroxide.
Given the stoichiometry,
mass of water =0.102⋅mol×2×18.01.g.mol−1=??⋅g.
Why did I multiply the mass in this equation by 2? Am I pulling your leg?
The answer is B.Let it sit
Using the mass/volume percentage method for percentages of the solution, you simply divide the grams of solute by the volume of the solution and multiply by 100 to get your percentage.
(75.0g/250mL)•100 = 30.0% solute
