Your body uses about 24 grams of Glucose to run cellular respiration. How many molecules does your body need for cellular respir
BartSMP [9]

Answer:

for the cellular respiration the human body needs 1.424 E21 molecules of glucose

Explanation:

mass glucose = 24 g

∴ Mw glucose = 180.156 g/mol

∴ 1 mol ≡ 6.022 E23 molecules

⇒ mol glucose = (24 g)×(mol/180.156 g) = 0.1332 mol glucose

⇒ molecules glucose = (0.1332 mol glucose)×(6.022 E23 molecules/mol)

⇒ molecules glucose = 1.424 E21 molecules

Sabendo que os calores de combustão do enxofre monoclínico e do enxofre rômbico são, respectivamente, - 297,2 kJ/mol e - 296,8 k
liq [111]

Responda:

+ 0,9kJ / mol

Explicação:

Dados os calores de combustão do enxofre monoclínico e enxofre rômbico como - 297,2 kJ / mol e - 296,8 kJ / mol, respectivamente para a variação na transformação de 1 mol de enxofre rômbico em enxofre monoclínico conforme mostrado pela equação;

S (mon.) + O2 (g) -> SO2 (g)

Uma vez que são todos 1 mol cada, a mudança na entalpia será expressa como ∆H = ∆H2-∆H1

Dado ∆H2 = -296,8kJ / mol

∆H1 = -297,2kJ / mol

∆H = -296,8 - (- 297,2)

∆H = -296,8 + 297,2

∆H = 297,2-296,8

∆H = + 0,9kJ / mol

Portanto, a mudança na entalpia da equação é + 0,9kJ / mol
