A chemical reaction is a process in which?
Chemical changes occur when a substance combines with another to form a new substance.These are called chemical reactions and are very hard to reverse.When chemical reactions take place, the atoms are rearranged and the reaction is accompanied by an energy change when new products are generated.
What evidence leads you to think that reactions in stars are very different from reactions like hydrogen combustion?
With the rate at which stars emit energy, any chemical process would exhaust a stellar mass of reactants in a relatively short time, yet stars last millions to billions of years. The only conclusion is that stars are powered by something many times more energetic than any chemical process.
What is the process by which a chemical change and a new substance is formed with new properties?
These are chemical reactions.
What process is the total of all the chemical reactions in an organism?
Answer metabolism
Is exercise a physical or chemical change?
Exercise is a chemical process but it is accompanied by many chemical reactions in the body.
Which is defined as new substances formed from chemical reactions?
Chemical reaction, a process in which one or more substances, the reactants, of a chemical reaction had a primary role in defining the science of chemistry as it is known today.
Which term is defined as new substances formed from chemical reactions-?
Chemical reaction, a process in which one or more substances, the reactants, of a chemical reaction had a primary role in defining the science of chemistry as it is known today.
A chemical change of original substance into one or more new substances is called?
Substances that undergo chemical change are called reactants.
What happens when a process is at chemical equilibrium?
Reactants and products stop forming.

In chemistry the state in which a chemical process and the reverse chemical process occur at the same rate such that the concentrations of reactants and products do not change is called what?
EQUILIBRIUM
Does anabolism require energy?
Anabolism is a metabolic process that requires energy. It refers to a set of chemical reactions involved in the synthesis of larger molecules from smaller components.
What initiates chemical reactions by breaking bonds in the reactants?
That process is called a chemical reaction.
Why is germination of a seed is a chemical change?
The chemical composition is changed during this process.
What is meant by the word chemical as used by scientsts?
The meaning of chemical is a process involving chemical reactions.
Why reversible reactions never complete?
Because reversible reactions are continuting process as well two way process.reactant n product convert into one another and in this way reaction will continue.
What are the substances that increase the rate of a chemical reaction called?
A catalyst can speed up a chemical reaction. Another possible answer in the Biological sense is that Enzymes speed up chemical reactions, but these enzymes are catalysts of the chemical reactions.Different catalysts catalyse different reactions. For example iron is used as a catalyst in the Haber process (manufacture of ammonia).
