Delta enthalpy = 2x386-3x1x432-3x942=-3350kJ/mol
Hi there ,
The Bohre's atomic model represents movement of electrons in specific orbit around the nucleus of an atom.
Hope it helps.
Answer:
B. 
Explanation:
The unit for rate is M/s while the unit for each molecule should be M. You can find the unit for k by putting the units for rate and the molecules into the equation
rate= k{X][Y]
M/s= k *
* 
k= (M/s) / (
)
k= 
You can also use this predetermined formula to solve this problem faster: k= 
Where n is the number of molecule. There are 3 molecule(2X and 1Y) so n=3, so
k= 
k=
=
= 
Mercury expands when it is heated. This process is called thermal expansion.
