C12+2ki ➡ 2kc1 + i2 is an example of which type of reaction?

Answer

Cl2+2KI ➡ 2KCl + I2 is an example of redox reaction.

Explanation

While Iodine is being oxidized.

Oxidation addition of electronegative elements such as Chlorine or increase in oxidation number. Reduction, addition of electropositive elements such as Potassium metal or decrease in oxidation number.

elements make up everything, and they combine to make compounds.

the answer is c

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
