Heat?
This is a sign of a chemical reaction.
Any reaction occur.
In the chemical installations of the plant.
no is not a chemical reaction
Any reaction occur.
Adding a catalyst a chemical reaction can occur with a lower activation energy.
Thermodynamically favorable reaction will occur. Also, if the neutral element is higher in the activity series than the charged element, then the reaction will occur.
yes
Heat energy is necessary for some chemical reactions to occur. Some chemical reactions are endothermic meaning they require or absorb energy for a chemical reaction to occur. Other chemical reaction are exothermic meaning they release energy when the chemical reaction takes place..
A chemical reaction occur.
