What else can I help you with?
What do chemical reactions require in order to begin?
depends what you are trying to do and loads of stuff dose a chemical reaction.
Chemical reactions that absorb energy will not occur without a source of energy true or false?
This is true. Energy is required to begin all reactions.
How is activation energy relates to the start of chemical reactions?
A chemical reaction begin only if the activation energy has a specific value.
What organs secrete enzymes which begin chemical digestion in the mouth?
The salivary glands in the mouth secrete enzymes in saliva that begin chemical digestion.
What is a Protein that speeds up chemical reactions in living things?
Enzymes are a type of protein that catalyse chemical reactions. There are many different types. They speed up the reaction by lowering the activation energy. This is the amount of energy needed to begin the reaction. The proteins that are vital to living things because they speed up chemical reactions are called enzymes. They are catalysts that lower the activation energy of chemical reactions.
How does heat speed up decomposition?
Decomposition involves chemical reactions and as a rough approximation, for many chemical reactions happening at around room temperature, the rate of reaction doubles for every 10°C rise in temperature. The reason for this is that for chemical reactions to happen, at the smallest scale, the individual chemical molecules have to bump into one another. As molecules warm up they begin to vibrate more and the chances of them bumping in to one another increases - the more bumps that happen, the faster the reactions go.
How do fires burn?
Fires involve chemical reactions. They generally require some kind of heat to begin the chemical reaction, and the reaction begins and releases heat which keeps it going. Like when we burn wood or paper. Heat the fuel sufficiently, it begins to burn and use oxygen out of the air, and it continues until it is cooled, smothered, or runs out of fuel. There are more "exotic" fires, but that's the basic idea in a nutshell.
Is a tree limb breaking a chemical or physical change?
It is a physical change: the wood (mostly cellulose) is not changed by the breaking. However, the living cells (if any) in the branch will begin to change chemically when exposed to the air and cut off from the xylem and phloem in the rest of the tree. Eventually the cells will die and the wood will rot (chemical changes).
How do reactions begin?
one particle has to travel rely fast
When should a foal begin its halter breaking on Howrse?
There is no halter breaking on Howrse.com. This is not something that you do with your horses on the game.
The main chemical of the stomach is to begin the digestion of?
to begin the digestion of proteins
Why is a spark of energy requieried to begin the chemical reaction of burning a fossil fuel?
The spark of energy is needed to initiate the combustion process by breaking the bonds within the fossil fuel molecules, creating reactive intermediates that can undergo further reactions with oxygen to produce heat and light energy. This initial energy input is required to overcome the activation energy barrier and start the combustion reaction.
