Why does the temperature increase and decrease during neutralization?
Neutralization is an exothermic chemical reaction and thus heat is given out.
How change will decrease the number of effective collisions during a chemical reaction?
- a lower concentration of reactants- a lower temperature
What chemical equation shows that no atoms are lost during a chemical reaction?
This is a balanced chemical reaction.
What new substances are formed during a chemical reaction?
The new substances formed during a chemical reaction are called Products.
What is the scientific word for a gas given off during a chemical reaction?
A reaction that emmits heat is called an exothermic reaction .
Why does the temperature increase and decrease during neutralization?
Neutralization is an exothermic chemical reaction and thus heat is given out.
Does the temperature increase or decrease when energy is released during a chemical reaction?
The temperature increases when energy is released during a chemical reaction.
A substance that shows a decrease in oxidation number during chemical reaction?
oxidising agent
What is the definition of catalysis?
Catalysis is the action to increase the reaction rate of a chemical reaction using substances called catalysts which are not transformed during this reaction.
How change will decrease the number of effective collisions during a chemical reaction?
- a lower concentration of reactants- a lower temperature
Does the total amount of mass during a chemical reaction increase?
The total mass of the compounds remain constant.
What undergoes no chemical change during a chemical reaction?
A catalyst undergoes no chemical change during a chemical reaction.
Do the movement of particles increase or decrease during condensation?
decrease
Is endothermic a chemical reaction?
Yes. A chemical reaction which absorbs heat during the reaction. The opposite to exothermic which releases heat during the reaction.
Undergo no chemical change during a chemical reaction?
A catalyst doesn't undergo a chemical change during a chemical reaction.
What is the chemical reaction called where water is removed during the reaction?
This chemical reaction is called dehydration.
What chemical equation shows that no atoms are lost during a chemical reaction?
This is a balanced chemical reaction.
