What results in a chemical change?
Chemical changes occur when a substance combines with another to form a new substance, called synthesis or, alternatively, decomposes into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. Some reactions produce heat and are called exothermicreactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. Understanding chemical changes is a major part of the science ofchemistry. When chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an energy change as new products are generated. An example of a chemical change is the reaction between sodium and water to produce sodium hydroxide and hydrogen. So much energy is released that the hydrogen gas released spontaneously burns in the air.
The rearranging of the chemical makeup of matter is called a what?
The rearranging of the chemical make-up of matter is called a chemical reaction. This is what will constitute a chemical change as it will alter the chemical composition.
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.
What speeds up reactions?
A catalyst. It does do by decreasing the energy required for the reaction to take place (activation energy).
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 enzymes control chemical reactions?
enzymes helps control chemical reactions by the chemical in it called collagen when enzymes enter your body they create a chemical reactions and controls the chemical reactions you get by eating too much acids.
What are molecules called that control all chemical reactions in the body?
I don't know about controlling ALL chemical reactions in the body, but biological catalysts are known as enzymes.
What is the substance called that helps chemical reactions happen in the body?
enzymes carry out chemical reactions, and enzymes are in proteins, so preoteins carry out chemical reactions
What refers to all of the chemical reactions in the body?
The sum total of all the chemical reactions occurring in the body are called the metabolism.
Chemical reactions in the body take place in what nutrient?
Chemical reactions in the body take place in water.
Chemical reactions take place in the body in what nutrient?
Chemical reactions in the body take place in water.
What accelerates chemical reactions that occur in the human body?
Catalysts that are called "enzymes".
What is a protein that helps run chemical reactions in the body?
Proteins involved in chemical reactions (speeding them up) are called enzymes. Note: most enzymes are proteins, but not all.
What controls the rate of chemical reaction in human body?
In the human body enzymes control the rates of chemical reactions. Enzymes speed up reactions by lowering the activation energy, or the amount of energy required for the reaction to occur.
The organic compounds that serve as helper molecules in many of the body's chemical reactions are called?
vitamins
How chemicals play an important role in the physiological aspect of the body?
Enzyematic reactions that occur from chemical reactions in the body speed up the activity and physiologically have everything to do with chemical reactions in the body.
Chains of chemical reactions in living organisms are called?
Bio-chemical reactions.
