H- is the one without electron
The temperature for the reaction is calculated as follows
delta H/ delta S
delta H=-70 Kj
delta S =-0.300 kj/k
temperature is therefore = -70kj/-0.300kj/k =233.33 K
Red blood cells carry oxygen throughout the human body
28.0 x 0.6424 = 18
25.0 x .6424 = 16.1
Mass = 34.1
