Sulfur, Charcoal, Potassium Nitrate.
Main components of Black Powder or Gun Powder. Ideal for using as propellant in fireworks.
It will have different burn speed depending on the level of components in the mixture.
It can burn very slowly or it can burn extremely fast.
Sulfur and Potassium Nitrate is used in matches, but there are more components to it than that. This can be some harder materials like sand or glass. This all mixed with a glue of some variety to make it stick to the end of the match. Friction make the match ignite. Matches can be made so that little friction will ignite them. This is however dangerous as a box of matches in your pocket may self ignite whilst you walk.
I suppose phosphor could be used, but this is highly toxic and extremely dangerous.
When a metal reacts with oxygen, it forms a metal oxide which is basic in nature. This can be distinguished from a non-metal oxide, which is acidic in nature. This difference in the nature of oxides can be used to identify whether a substance is a metal or non-metal.
No, Acetone is commonly used in metal cleaning prior to welding and painting.
Carbon is a non-metal that is commonly used in water purification processes. It is used in the form of activated carbon to adsorb impurities, such as chemicals, organic compounds, and pollutants, from water.
Oxygen is a non-metal. It is a reactive gas that is essential for sustaining life and is found in the non-metal group on the periodic table.
Neon is a non-metal. It is one of the Noble Gasses which are all non-metals.
Are Non-metal elements used in computers
Chlorine is a non-metal. It is used to kill fungi.
The disadvantages of crackers are the huge noise, accidents caused by crackers and the polution in the city.
Silicon is the non-metal used to make micro-chips for computers/electronics.

Phosphorous (P, #15) is a non-metal. It reacts vigorously with oxygen, which is why it is used for matchheads.

No, Acetone is commonly used in metal cleaning prior to welding and painting.
the non-metal element iodine is used as an antiseptic
they can be metal, metalliod or non-metal
Graphite is the only non-metal exception that can conduct electricity. Hence, even though graphite is a non-metal, it is used in batteries.
