Answer:
1.99V
Explanation:
Balanced redox reaction equation:
3CU2+(aq) + 2Al(s) ------> 3Cu(s) + 2Al3+(aq)
E°cell= E°cathode- E°anode
E°cell= 0.34-(-1.66)
E°cell= 2.0V
From Nernst equation:
E= E°cell - 0.0592/n logQ
E= 2.0 - 0.0592/6 log [3.43]/[1.63]
E= 2.0- 0.0032
E= 1.99V

Explanation:
Well, dam is used as the main source of water that irrigate the whole ecosystem.
dam will hold the water to be used by the bottom half of the ecosystem, but this could result in negative effect such as it will flood will unclean water since the water is not flowing as normal.
Answer:
5.6 L is the final volume for SO₂ at STP condtions
Explanation:
The reaction is: S(s) + O₂ (g) → SO₂ (g)
Ratio for this reaction is 1:1, if we see stoichiometry.
1 mol of sulfur can react to 1 mol of oxygen in orden to produce 1 mol of sulfur dioxide.
Then, 0.250 moles of sulfur can produce 0.250 moles of SO₂.
If we solve this by a rule of three, we can say:
At STP 1 mol occupies 22.4L
Then, 0.250 moles will be contained at (0.250 mol . 22.4L) /1mol = 5.6 L
If we apply the Ideal Gases Law:
P . V = n . R . T
1 atm . V = 0.250 mol . 0.082 . 273K
V = (0.250 mol . 0.082 . 273K) / 1atm → 5.6 L
