Calculate the δhrxn for the following reaction:
ch4 (g) + 2cl2 (g) --> ch2cl2 (g) + 2hcl (g)
use the following reaction and given δh's:
ch4 (g) + cl2 (g) --> ch3cl (g) + hcl (g), δh = -99.60 kj
ch3cl (g) + cl2 (g) --> ch2cl2 (g) + hcl (g), δh = -105.8 kj

- "the acute form of diverticulitis can manifest itself with one or more severe attacks of infection and inflammation.

the inflammation of diverticulitis can eventually result in a bowel obstruction, which may cause constipation, thin stools, diarrhea, abdominal swelling or bloating, and abdominal pain."

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
