Are chemical reactions useful?
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.
Is energy always involved in making or breaking chemical bonds?
no, some reactions are spontenous.
Substances are changed into different substances when bonds break and form during?
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.
How are chemical reactions described?
Chemical reactions are described based on observations. It may be in terms of changes in color, state of matter, or density.
What are three types of chemical reactions?
The three types of chemical reactions are: synthesis, decomposition, and replacement.
What are some fast reactions in everyday life?
Fireworks and wood burning are good examples of fast chemical reactions =]
What comes out of chemical reactions?
4 useful chemical reactions are: fermentation, smelting combustion and electrolysis
Are chemical reactions useful?

What are some of the chemical reactions that must occur to break down waste and how fast do they occur?
we must throw our garbage where it suppost to go.
What energy helps chemical reactions to form?
Heat helps chemical reactions to take place. Light can also cause some chemical reactions to take place.
Why might it not always be possible to determine the reactants and the products in a reaction explain your answer in terms of a chemical equilibrium?
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
What are some bad chemical reactions?
nothing
What are some of unwanted chemical reactions?
magazines
What is a sentence for reactions?
The students analysed the chemical reactions.Detectives watch for the suspect's reactions and body language when questioning them.
Are chemical changes irreversible If yes then what about the chemical reactions that are reversible Don't we say that all chemical reactions are chemical changes?
some chemical changes can be reversed but they are hard to reverse usually
What is a consequence if the enzyme was missing from a chemical reaction?
Enzymes speed up chemical reactions, so therefore it wouldn't happen as fast.
What chemical reaction produces the sun and energy?
These are not chemical reactions but thermonuclear reactions.
