Which compound is acting as a base in this reaction? h2s ba(oh)2 h2o bas

Answer

The base is Ba(OH)2

Explanation

This equation follows the path of, acid +base---salt +water

H2S +Ba(OH)2BaS +2H2O

Where H2S is the acid, Ba(OH) is the base and 2H2O is water.

Here, Barium hydroxide reacts with hydrogen sulfide to give barium sulfide and water.

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.
