Answer:
This is an example of scientific investigation being led by inductive reasoning.
Explanation:
Inductive reasoning is the type of reasoning used to make broad generalizations from specific observations. We have certain pieces of data and make conclusions based on them. In the given example, astronomers have made a specific observation - that the orbit of Uranus isn't uniform. Based on that fact, they made a broader conclusion - that there is another planet. There are probably more things that could lead to the same conclusion.
The opposite is deductive reasoning, where a person starts off with a broad generalization and tries to make specific, logical conclusions based on it.

Answer:
0.058M is molarity of the solution
Explanation:
Molarity is defined as the ratio between the moles of solute (In this case, MgSO₄) and the liters of solution.
In the problem:
<em>Moles MgSO₄: 0.32 moles</em>
<em>Liters solution: 5.5L</em>
<em />
Molarity is:
0.32 moles / 5.5L =
0.058M is molarity of the solution
1) moles = mass/mR
CaCO3 Mr = 40 + 12 + (16×3)
= 52 + 48
= 100
mass = 15
so the moles would be 15 ÷ 100
which is 0.15 moles of CaCO3
2) moles = mass ÷ Mr
Mr of Al2O3 = 27 + (16×3)
= 27 + 48
= 75
mass = 204
so the moles would be 204/75 which is 2.72 moles of Al2O3
