12oz of water initially at 75oF is mixed with 20oz of water intiially at 140oF. What is the final temperature?

Explanation:

= First mass of water = 12 oz

= Second mass of water = 20 oz

= Temperature difference of the solution with respect to the first mass of water =

= Temperature difference of the solution with respect to the second mass of water =

c = Specific heat of water

As heat gain and loss in the system is equal we have

The final temperature of the solution is .

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

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