What do geologists call the underground molten mixture of rock-forming substances, gases, and water that is found in the mantle?

B. magma
C. batholith
D. slurry

i think it is true since you can test the answer and can use observations to complete it.

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.
