What else can I help you with?
Has the number of subatomic particles changed?
No, from 80 years.
What subatomic particles is lost or gained during a chemical reaction?
During a chemical reaction, electrons are the subatomic particles that are lost or gained. When an atom loses electrons, it becomes positively charged and when it gains electrons, it becomes negatively charged. This process is responsible for the formation of chemical bonds and the creation of new compounds.
Why is a chemical reaction called a chemical reaction?
Because this reaction involve chemical compounds as reactants and products and the chemical structure and composition being changed.
Why is the boiling of water a physical reaction and not a chemical reaction?
During boiling the chemical composition is not changed.
A compound can only be changed how?
A compound can only be changed by a chemical reaction.
What is a substance that is changed in a chemical reaction Called?
A substance that undergoes change in a chemical reaction is called a reactant.
Is sawing a log chemical reaction?
No, that would probably be considered a physical change. It is only a chemical reaction its chemical makeup is changed.
What change could happen during a chemical reaction?
the chemical shall be changed
What makes a chemical reaction?
to see if a chemical has changed look out for bubbling and or fizzing
According to the law of conservation of matter the number of is not changed by a chemical reaction.?
According to the law of conservation of matter, the total mass of substances before a chemical reaction is equal to the total mass after the reaction. This means that the number of atoms is not changed during a chemical reaction, only their arrangement.
Is it true In a chemical reaction reactants are changed into products?
True
Which part of a chemical reaction is most changed by enzyme activity?
The speed of the reaction is most changed by enzyme activity, as enzymes can greatly accelerate the rate at which chemical reactions occur by lowering the activation energy required for the reaction to proceed.
