Question

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

Answer 1

Answer:

$6CO_2 + 12H_2O + Energy->C_6H_{12}O_6 + 6O_2 + 6H_2O$

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:

$6CO_2 + 12H_2O + Energy-> C_6H_{12}O_6 + 6O_2 + 6H_2O$

is the only endothermic reaction.

$6CO_2 + 12H_2O + Energy->C_6H_{12}O_6 + 6O_2 + 6H_2O$

Answer 2

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.
