Answer:
I would think the correct answer would be B and D.
Explanation:
The information the institutions gathered doesn't tell whether the temperature increased or decreased so it couldn't be A. And the data that is gathered by each institute is similar to one another, so it couldn't be C. Therefore, you're left with B and D.

Explanation:
Answer is: the mass of the oxygen is 2.37 grams.
Balanced chemical reaction: 2Mg + O₂ → 2MgO.
m(Mg) = 3.6 g; mass of magnesium.
n(Mg) = m(Mg) ÷ M(Mg).
n(Mg) = 3.6 g ÷ 24.3 g/mol
n(Mg) = 0.149 mol.; amount of the magnesium.
n(O₂) = ?
From chemical reaction: n(Mg) : n(O₂) = 2 : 1.
n(O₂) = n(Mg) ÷ 2.
n(O₂) = 0.149mol ÷ 2.
n(O₂) = 0.075 mol; amount of the oxygen.
m(O₂) = m(O₂) · M(O₂).
m(O₂) = 0.075 mol · 32 g/mol.
m(O₂) = 2.37 g; mass of the oxygen.

<span>An insect would have an easier time walking on the surface of water than on the surface of ethanol. Water's stronger intermolecular forces lead to higher surface tension. Higher surface tension allows water to support the insect. I hope this helps.</span>
