How much energy in joules will be required to raise the temperature of 50.0 g of water from 20 degrees C to 60 degree C

8368 Joules

Explanation:

The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.

Q = Heat absorbed or released =?

c = specific heat capacity of water =

Initial temperature of water = =

Final temperature of water =  =

Change in temperature ,

Putting in the values, we get:

Thus energy in Joules required is 8368.

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.
