Exothermic refers to a reaction that produces heat. When you balance the equation the energy released when new bonds are formed is greater than the energy use when bonds are broken.
An endothermic reaction takes in heat as it requires more energy to break its bonds than it has from the bonds it creates.
Endothermic is when a reaction requires energy to be put in for it to run and exothermic is when a reaction releases energy.
The combustion is exothermic.
freezing is exothermic, melting is endothermic, evaporation is endothermic, condensation is exothermic.
Freezing is exothermic, as the substance that is freezing loses energy to its surroundings.
Silicon is an element - endothermic or exothermic is meaningless.
