I honestly have no idea but brainly is making me answer this :)
Answer:
Wind energy
An ideal source of energy needs to be reliable, cost effective, safe and must lead to almost zero adverse environmental impact.
Wind energy is energy obtained from air moving at high velocity. This energy is harvested using windmills which convert mechanical energy to electrical energy.
Wind is inexpensive because it occurs naturally. However, a large expanse of land is required in order to mount sufficient number of windmills that will generate enough electrical energy for practical purposes.
This method of electricity generation is safe and does not lead to any environmental hazard unlike the burning of fossil fuels, use of nuclear energy or loss of habitat due to hydroelectric power generation.

Answer:
0.68 V
Explanation:
For anode;
3Mg(s) ---->3Mg^2+(aq) + 6e
For cathode;
2Al^3+(aq) + 6e -----> 2Al(s)
Overall balanced reaction equation;
3Mg(s) + 2Al^3+(aq) ----> 3Mg^2+(aq) + 2Al(s)
Since
E°anode = -2.356 V
E°cathode = -1.676 V
E°cell=-1.676 -(-2.356)
E°cell= 0.68 V
Answer: -
A 3.00-l flask is filled with gaseous ammonia, NH₃. the gas pressure measured at 26.0 ∘c is 1.55 atm . assuming ideal gas behavior, 3.23 grams of ammonia are in the flask
Explanation: -
Volume V = 3.00 L
Pressure P = 1.55 atm
Temperature T = 26.0 °C + 273 = 299 K
We know the value of Universal gas constant R = 0.082 L atm K−1
mol−1
We use the ideal gas equation
PV = nRT
Number of moles of Ammonia n = 
= 
= 0.19 mol
Molar mass of NH₃ = 14 x 1 + 1 x 3 = 17 g / mol
Mass of NH₃ = Molar mass of NH₃ x number of moles of NH₃
= 17 g / mol x 0.19 mol
= 3.23 g
