8. A sample of neon gas occupies a volume of 752 mL at 25°C. What temperature will the gas have when the volume is 815 mL if the pressure remains constant?
a. 273 K
315 K
b. 308 K
d. 323 K
C.

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.

you need to have a picture of the atom that way we can answer it
