Answer:
Cl2, because it gained electrons
Explanation:
2Fe^2+ went from 2+ to 3+
Cl2 went from 0 to -1
Reduction-gain
Oxidation-loss
- means gained and + means loss trust me it doesn't make sense but if you stick to it it'll be a lot easier for you.

Answer:
292.4 g
Explanation:
- 2Al + 3H₂SO₄ → 3H₂ + Al₂(SO₄)₃
First we <u>convert 53.7 g of Al into moles</u>, using its<em> molar mass</em>:
- 53.7 g ÷ 27 g/mol = 1.99 mol Al
Then we <u>convert Al moles into H₂SO₄ moles</u>, using the <em>stoichiometric coefficients</em>:
- 1.99 mol Al *
= 2.98 mol H₂SO₄
Finally we <u>convert 2.98 moles of sulfuric acid into gram</u>s, using its <em>molar mass:</em>
- 2.98 mol H₂SO₄ * 98 g/mol = 292.4 g
Answer:
The new temperature is 527.15 ºC.
Explanation:
<u>Charles’s law</u><u> states that the volume of a fixed amount of gas maintained at constant pressure is directly proportional to the absolute temperature of the gas</u> (the absolute temperature is the Kelvin temperature).
We need to calculate the temperature after the expansion, that is T₂. For that, we use Charles' law:
Because we have to use the absolute temperature, we convert ºC to K adding 273.15:
<u>T₁</u> = 127 ºC + 273.15 ºC = <u>400.15 K</u>
T₂ = 800.3 K
We substract 273.15 to the result to convert it back to ºC:
T₂ = 800.3 - 273.15 = 527.15 ºC.
