A patient arrives in the emergency room with a burn caused by steam. Calculate the heat that is released when 14.5 g of steam at 100. ∘C hits the skin, condenses, and cools to body temperature of 37.0 ∘C. (For water, 540 cal (2260 J) is needed to convert 1 g of water to vapor at 100 ∘C.)

36,592.1J or 36.5921KJ

Explanation:

first convert to steam

14.5 g of steam  at 100∘C

To covert to water vaporor steam, becomes

14.5g x 2260 J of energy per gram of steam

=32,770J

Also, Quantity of heat released when the temperature is reduced from 100 ∘C to 37 ∘C, we will use the formulae,

q= m C ΔT

Where specific heat capacity of water C = 4.184 J/g.C

mass= 14.5g

Change in temperature= 100∘C-37∘C= 63∘C

we will now have  

= 14.5 g x 4.184 J/g.Cx ( 100 - 37) C = 3,822.084 J= 3822.1J

Therefore total energy released = 32,770 J + 3822.1 J =   36,592.1J

OR converting to KJ becomes=36,592.1/1000=36.592KJ

atomic number of carbon is 6

electronic configuration of carbon is 1s²2s²2p²

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

give me abc and i will get it for u.
