Hi! The answer is "A. Anopheles", malaria is a mosquito-borne parasitic spread by anopheles mosquitoes.
5H2O contain 9 moles of oxygen atom.
Answer:
5.11 mol/L.
Explanation:
<em>H₂(g) + I₂(g) ⇄ 2HI(g), Kc = 53.3.</em>
∵ Kc = [HI]²/[H₂][I₂]
[H₂] = 0.70 mol/1.0 L = 0.70 mol/L.
[I₂] = 0.70 mol/1.0 L = 0.70 mol/L.
∵ Kc = [HI]²/[H₂][I₂]
∴ [HI]² = Kc[H₂][I₂] = (53.3)(0.70)(0.70) = 26.117.
<em>∴ [HI] = √26.117 = 5.11 mol/L.</em>
