Constructed Response (3 paragraphs) 30 pts Water is a very common substance on Earth, covering over two-thirds of its surface. But less than one percent of the water on Earth is fresh water that can be used by humans. As human populations grow, the stress on water resources will continue to increase.

Describe how we as a global community might come together to save more water or use water that needs to be processed to consume (ocean water for example)

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.

i think its 100

i hope this !
