Edurite - Aluminum Hydrochloric Acid Reaction

Question:When aluminum foil is placed in hydrochloric acid, nothing happens for about 30 seconds or so.This is followed by vigorous bubbling and the eventual disappearance of the foil. Explain these observations. Answers:The reaction that occurs is 2 Al + 6 HCL ---> 2 AlCl3 + 3 H2 So the bubbling gas is hydrogen.The reason there is a slight delay is that aluminum forms a very thin oxide layer

Sulphur Grade 11 Chemistry | Solutions | Khullakitab

Since S8 molecule is larger than O 2 molecule, the van-der Waals force between the S8 molecules is stronger than that between the O 2 molecules and the melting point of sulphur is also higher than that of O 2. Hence sulphur exists as solid and O 2 exists as gas. iii. Sulphur trioxide is not directly dissolved in water to manufacture H 2 SO 4.
