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)

it is the most commonly accepted one

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.

: )

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
