Which reaction is endothermic? HCl + NaOH Right arrow. NaCl + H2O + 58 kJ 6CO2 + 12H2O + energy Right arrow. C6H12O6 + 6O2 + 6H2O 2Na + Cl2 Right arrow. 2NaCl + energy 2C2H6 + 7O2 Right arrow. 4CO2 + 6H2O + 2,502 kJ

An endothermic reaction is a reaction in which energy is absorbed such as;  6CO2 + 12H2O + energy > C6H12O6

An endothermic reaction is a reaction in which energy is absorbed. The enthalpy change for an endothermic reaction is positive. The energy of the products is greater than the energy of the reactants.

The reaction that is endothermic in the list is the reaction;   6CO2 + 12H2O + energy > C6H12O6 . Energy is a product in the reaction. This means that energy is absorbed in the process.

Explanation:

-An endothermic reaction is a chemical reaction that gains or absorbs heat from its surrounding in the form of heat.

-During the reaction, the temperature of the surrounding reduces.

-From the reactions given:

is the only endothermic reaction.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
