1. Skin and respiratory allergic reactions
2. Baking soda and vinegar
3. Caustic soda exposed to liquid
4. Many different forms of acids exposed to almost everything will cause an immediate chemical reaction
yes some chemical reactions are harmful to us. as digestion of food, photosynthesis, decomposition of organic waste are some examples of the useful chemical reactions.
no, some reactions are spontenous.
Chemical bonds are made and broken by chemical reactions. After chemical bonds have been broken, then energy is released, and if a chemical bond is made, then energy is absorbed.
Chemical reactions are described based on observations. It may be in terms of changes in color, state of matter, or density.
The three types of chemical reactions are: synthesis, decomposition, and replacement.
Fireworks and wood burning are good examples of fast chemical reactions =]

Heat helps chemical reactions to take place. Light can also cause some chemical reactions to take place.
1 some reaction can be very fast and consume the products of other reactions as they form, for example multistage reactions like blood clotting. 2 some reactions are highly reversible such as the oscillating clock reactions

Chemical reactions can produce a variety of products, including gases, liquids, solids, or energy in the form of heat or light. The specific products depend on the reactants involved and the nature of the reaction.
Enzymes speed up chemical reactions, so therefore it wouldn't happen as fast.
some chemical changes can be reversed but they are hard to reverse usually
The students analysed the chemical reactions.Detectives watch for the suspect's reactions and body language when questioning them.
Candle and all Chemical reactions
These are not chemical reactions but thermonuclear reactions.
