Crystals of the covalent compounds always contain:(i) Atoms as their structural units (ii) Molecules as structural units (iii) Ions held altogether by electrostatic forces (iv) High melting pointsAnswer: (i)
Normal butane (C4H10) is stored as a compressed liquid at 90°C and 1400 kPa. In order to use the butane in a low-pressure gas-phase process, it is throttled to 150 kPa and passed through a vaporizer. The butane emerges from the vaporizer as a
