Ahot bowl of soup cools according to newton's law of cooling. its temperature (in degrees fahrenheit) at time t is given by t(t)=68+), where t is given in minutes.

a. what was the initial temperature of the soup?
b. what is the temperature of the soup after 15 minutes?
c. how long after serving is the soup 125 degrees f?

heat or electricity in the atmosphere- c.

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.
