Os produtos da combustão do H₂S e SO₂ gasoso são mostrados em reações abaixo. H₂(g) + S(s) → H₂S(g) Δ H = -21 KJ S(s) + O₂(g) → SO₂ (g) Δ H = -297 K H₂(g) + 1/2O₂(g) → H₂O(g) Δ H = -242 KJ conclui-se que a energia desprendida na combustão de 1 mol de H₂S(g) segunda a equação é: H₂(g) + 1/2O₂(g) → SO₂ (g) + H₂O(g) Δ H = ? * 1 ponto
a) - 67 Kj
b) + 34 Kj
c) - 560 Kj
d) -34 Kj
e) - 518 Kj

answer: at room temperature (roughly 20 degrees c), you can dissolve 203.9 grams (or 200 grams) of sugar in 100 ml of water. as water temperature increases, the amount of sugar that will dissolve increases, up to about 500 grams of sugar in 100 ml water at 100 degrees c.
