Hydroelectric energy is produced.
Answer:
57.4 g
Explanation:
30.4 g Al will produce 57.4 g Al 2 O 3 30.4 g O 2 will produce 64.6 g Al
2 O 3 .The limiting reagent is aluminum, and the maximum amount of aluminum oxide that can be produced in this reaction is 57.4 g
Answer:
The concentration of NO₂ is 0,0230M
Explanation:
The equilibrium constant, kc, express the ratio in equilibrium between products and reactants. For the reaction:
N₂O₄(g) ⇄ 2NO₂ (g) <em>kc = 0.211 at 100°C</em>
kc = ![\frac{[NO_{2}]^2}{[N_{2}O_{4}]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BNO_%7B2%7D%5D%5E2%7D%7B%5BN_%7B2%7DO_%7B4%7D%5D%7D)
In equilibrium:
0,211 = ![\frac{[NO_{2}]^2}{[0,00251]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BNO_%7B2%7D%5D%5E2%7D%7B%5B0%2C00251%5D%7D)
5,2961x10⁻⁴ = [NO₂]²
<em>0,0230 M = [NO₂]</em>

Answer:
The mesosphere is 22 miles (35 kilometers) thick. ... Those meteors are burning up in the mesosphere. The meteors make it through the exosphere and thermosphere without much trouble because those layers don't have much air. But when they hit the mesosphere, there are enough gases to cause friction and create heat.
Unsaturated solution: a solution in which more solute can be dissolved.
Explanation:
Salt dissolved in water or even sugar dissolved in water is an unsaturated solution if the quantity of dissolved salt/sugar is below the saturation point.
