What is the total number of Joules lost when 10. grams of water at 80.°C is cooled to 60.°C?

Explanation:

84

precipitation

explanation:

when it goes from cloud to rain/back to earth in the form of rain

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.
