Aluminum. chemical element with symbol Al
The correct answer is Electrical Energy.
<span>The </span>authentic<span> voice of Bettina is </span>obtained through<span> a transducer, which is the microphone which converts the sound </span>energy<span> to </span>electric<span>. </span>it's far<span> then amplified </span>by<span> an amplifier </span><span>and </span>introduced<span> to the </span>target audience by means of some other<span> transducer, such as the speakers which </span>changes the electrical energy lower back<span> into sound </span>energy<span> at a louder </span>stage.
<span>Missing question: The first-order rate
constant for the decomposition of N2O5, 2N2O5(g)→4NO2(g) + O2(g) at 70°</span><span>C is 6.82×10−3 s−1. Suppose we start with 2.70×10−2 mol of
N2O5(g) in a volume of 1.8 L .
</span>c₀(N₂O₅) = 0,027 mol ÷ 1,8 L.<span>
c</span>₀(N₂O₅) =
0,015 mol/L.<span>
c(N</span>₂O₅) = 0,019 mol/ 1,8 L = 0,01055 mol/L.<span>
k = 6,82·10</span>⁻³ s⁻¹.<span>
ln c(N</span>₂O₅) =
ln c₀(N₂O₅) -
k·t.<span>
t = (ln c</span>₀(N₂O₅) - ln c(N₂O₅)) ÷ k.<span>
t = 0,35 ÷ 0,00682 s</span>⁻¹.<span>
t = 51 s = 0,86 min.</span>
