Question

examples of endothermic reaction​

Answer 1

Answer:

reactions which are AC companied bi fall in temperature for those in which heat is absorbed. such reactions are called endothermic reactions. for example when barium hydroxide , BA(oh) 2 , is added into ammonium chloride nh4cl, taken in a test tube and mixed with the glass Rod, then on touching the bottom of the test tube, it is found to be cooler. this is due to the following endothermic reaction taking place:

barium hydroxide + ammonium chloride

__ Barium Chloride + Ammonium hydroxide.
