Σελίδα 42 - Bring a cold porcelain dish into a small luminous Bunsen flame. Note the deposit. What is this form of carbon called ? In what other forms does carbon exist ? What properties have all of these forms in common ? c.
Σελίδα 22 - Instead of a plain tube, use one graduated into cubic centimetres. Enclose 60 to 80 cc. air in the tube over water. Arrange the tube so that the level of the water inside and outside is the same. Note the temperature of the air and the height of the barometer.
Σελίδα 32 - Pour the clear solution into an evaporating-dish, cover it loosely with a filter paper, and set it aside in the hood. The carbon disulfide soon evaporates, the sulfur being deposited in crystals. Examine these with a magnifying-glass.
Σελίδα 53 - Burn off a platinum wire in the flame until it ceases to impart any color to the flame, then dip in the solution and bring it immediately to the flame.
