Help with endothermic and exothermic reactions? - carbonated water frozen
Sort these changes, the reaction is exothermic or endothermic:
a) combustion of gasoline
Water b) steam
Ice-cold water c)
d) sodium carbonate to neutralize the hydrochloric acid
If you tell me what each response, and why.
Thank you for your time and effort

Carbonated Water Frozen Help With Endothermic And Exothermic Reactions?
2 comments:
Bond breaking requires heat and radiates heat that rules. Thus, exothermic bonds have more than they do burst. During the combustion of fuel, break the bonds of CO2, but also new obligations and H2O, they provide more energy than the breaking of bonds were. You may also notice that when you burn gasoline gets hot, if they are too close together. Turn water is endothermic, the energy needed to break the intermolecular bonds between water molecules. In water, the ice is exothermic, because there are commitments that are made in the crystal structure. Sodium carbonate reacts with hydrochloric acid Severing ties with the energy, but also make connections gives you energy. And for most of this neutralization is exothermic.
Make sure you understand the terms exothermic and endothermic. Who can help you with questions.
The reaction is exothermic, if the reaction produces heat. eg fire)
Reaction is endothermic, when the heat required for a reaction is occurring.
for example) to boil an egg
