Ti
enzyme works as a catalyst before and after the reaction it is preserved
Measuring it before, after and during the reaction with a thermometer.
To determine whether the reaction was exothermic (gave off heat) or endothermic (absorbed heat).
It does not change

Ignition temperature is the temperature a substance needs to reach before it is combustible. Activation energy is the energy required to start a reaction occurring. Temperature is directly affected by heat. Heat is a form of energy. Therefore as you add energy to a substance it heats up. It will reach its ignition temperature and combust. The combustion is the reaction.
This is a thermal decomposition reaction: new compounds are obtained by heating.
Total mass before reaction=Total mass after reaction Proven by the law of mass conversion: Matter cannot be created or destroyed; it can only change forms.
In a chemical reaction, the mass of the reactants is conserved. This means that the total mass of the reactants before the reaction is equal to the total mass of the products after the reaction. This is known as the law of conservation of mass.
During a chemical reaction, atoms are rearranged and bonded together in new ways, forming different substances. The total number of atoms remains the same before and after the reaction, as atoms are neither created nor destroyed in a chemical reaction.
Before it starts to rain, the temperature may drop slightly due to the cooling effect of the rain clouds blocking sunlight. However, sometimes the temperature can remain warm and humid leading up to a rainstorm.
There must be a light reaction first before dark reaction. This is so that there is something to be compared.
