How many milliliters of 0.145 M HCl are needed to completely neutralize 49.0 mL of 0.100 M Ba(OH)2 solution? ​

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.

use quiz let it tells you all the answers thats what i use

the answer is 2-methylbutane. i just took a quiz and i got it wrong and this is what my teacher sai the correct answer was.
