A5.10 g sample of iron is heated from 36.0 to 75.0 c. the amount of energy required is 89.5 j. the specific capacity of this sample of iron

a.) 17800 j/g c
b.)0.900 j/g c
c.)11.7 j/g c
d.) 0.450 j/g c
e.) 2.22 j/g c

Option (D) is the correct answer.

Explanation:

The given data is as follows.

       mass = 5.10 g,            ,

       ,          q = 89.5 J

It is known that relation between heat energy and specific heat capacity is as follows.

                           q =

Hence, putting the given values into the above formula to calculate specific heat capacity as follows.

                           q =

                        89.5 J =

                        89.5 J =

                              C =

Thus, we can conclude that the specific capacity of this sample of iron is .

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

orbital diagram of carbon is as shown here in the image.

a electronegativity decreases beacuse the size of nucleus is bigger.
