O D. Their particles all have the same chemical formula.

2b2t

explanation:

2b2t

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.

the correct answer would be b) volume versus temperature, because they are also directly proportional.

it would only be the stuff in module eight so you need to study all the lessons in that you also could check the flvs

hope this : )
