What are some general physical properties of non-metals?

Non-metals are not strong, malleable, ductile, or sonorous. They have lower melting and boiling points than metals and are poor conductors of electricity and heat, with low densities.

How do non-metals typically react with oxygen?

Most non-metals react with oxygen to form oxides.

What is a unique property of graphite among non-metals?

Graphite is an exception among non-metals as it is a good conductor of electricity.

How is hydrogen gas typically tested in the laboratory?

Hydrogen is tested by introducing it to a lighted splint, which is put out with a 'pop' sound.

What are the physical properties of hydrogen?

Hydrogen is a colorless, odorless, and tasteless gas, less dense than air, with a boiling point of 21K and a melting point of 14K.

Describe the industrial manufacture of hydrogen.

Hydrogen is manufactured by cracking, electrolysis of brine, and from natural gas.

What is the test for oxygen in the laboratory?

The test for oxygen is that it relights a glowing splint.

How is oxygen industrially manufactured?

Oxygen is manufactured by fractional distillation of liquid air.

What role does the ozone layer play in protecting Earth?

The ozone layer traps dangerous ultraviolet (UV) radiation from the sun.

What is a chemical test for water?

Water can be tested using white anhydrous copper (II) sulfate, which turns blue when water is present.
