Answer:
The electron configuration for a
Mn3+ ion is [Ar]3d4
Explanation:
Concentration :
196 g/L and 4 N
<h3> </h3><h3>Further explanation</h3>
The concentration of a substance can be expressed in several quantities such as moles, percent (%) weight / volume,), molarity, molality, parts per million (ppm) or mole fraction. The concentration shows the amount of solute in a unit of the amount of solvent.
500 cc of 2M H₂SO₄
V = 500 cc = 0.5 L
mol H₂SO₄
mass H₂SO₄ (MW = 98 g/mol)
concentration in g/L :
concentration in normality
Relationship between normality and molarity
N = M x n (n=valence , amount of H⁺ or OH⁻)
so :
In a way, all of the answers could be argued for (for example: in the first option: if the scientists' opinions are understood to be "informed understanding of the causes of events"), but one of the options is the best:
Scientific laws describe specific relationships in nature without offering
an explanation.
The reason why I think this is true is that many laws are phased too short and too concise to provide comprehensive explanations, instead they describe the relationships that must hold.
One of the options is pplain false:
Scientific laws explain why natural events occur. -"Scientific laws were theories that have been tested, proven, and adopted as laws." - since they are not adopted as laws.
Answer:
The less mass in a given volume of air the less dense the air is going to be.
