What type of reaction is represented by the following example? 2co2 (g) + 4h2o (l) + 1452 kj 2ch3oh (l) (g) + 3o2 (g) exothermic endothermic

endothermic  

I hope this helped :)

Answer : The given reaction is an example of endothermic reaction.

Explanation :

Endothermic reaction : It is a type of chemical reaction in which the energy is absorbed by the surroundings. In this reaction, the energy of reactants are less than the energy of products.  In this reaction, the energy is given to the system.

Exothermic reaction : It is a type of chemical reaction in which the energy is released into the surroundings. In this reaction, the energy of reactants are more than the energy of products. In this reaction, the energy is released from the system.

The given balanced chemical reaction is,

In this reaction, the 1452 KJ energy is given to the system. So, the given reaction is an example of endothermic reaction.

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
