B

The net force is 8 because there is 20 amount of force and the drag is 12 because of the drag it goes to the left, because the net force is larger on the left side

Variables,control,conclusion and finally scientific theory

Answer : option c) heat is released during the process.explanation :

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.
