Answer:
See explanation
Explanation:
We have to start, remembering the mechanism behind the <u>McLafferty rearrangement</u>. The hydrogen in the g<u>amma carbon</u> (in this case, carbon 5) would be removed by a <u>heterolytic rupture</u> due to the <u>cation-radical</u> placed in the oxygen of the <u>carbonyl group</u>. Then we will have several heterolytic ruptures. Between <u>carbons alpha and beta</u> (in this case, 4 and 3) and a rupture in the <u>carbonyl group</u>. Due to these ruptures, <u>two double bonds would be formed</u>. One double bond in the alcohol cation-radical and the other one in the alkene.

Answer:
c) 0.080 M Al₂(SO₄)₃
Explanation:
Ion [SO₄²⁻] concentration of each solution is:
a) 0.075 M H₂SO₄: <em>[SO₄²⁻] = 0.075M</em>. Because 1 mole of H₂SO₄ contains 1 mole of SO₄²⁻
b) 0.15 M Na₂SO₄: <em>[SO₄²⁻] = 0.15M</em>. Also, 1 mole of Na₂SO₄ contains 1 mole of SO₄²⁻
c) 0.080 M Al₂(SO₄)₃ [SO₄²⁻] = 0.080Mₓ3 =<em> 0.240M</em>. Because 1 mole of Al₂(SO₄)₃ contains 3 moles of SO₄²⁻.
<h3>Thus, the soluion that has the greatest [SO₄²⁻] is 0.080 M Al₂(SO₄)₃</h3>
Answer:
D.) 2,000 kilocalories would be the correct answer.
Explanation:
Answer:
Explanation:
Boyle's law for gases states that, at constant temperature, the volume and pressure of a fixed amount of gas are inversely related.
Mathematically, that is:
Here, you have:
Then, you can solve for V₂:
Substitute and compute:
- V₂ = 14.1 KPa × 2.4L / 84.6 KPa = 0.40 L ← answer
