At a certain temperature, 0.760 mol so3 is placed in a 1.50 l container. 2so3(g) = 2so2(g) + o2(g)at equilibrium, 0.130 mol o2 is present. calculate kc.

Explanation:

Moles of SO₃ = 0.760 mol

Volume = 1.50 L

[SO₃] = 0.5067 M

Considering the ICE table for the equilibrium as:

Given:    

Equilibrium concentration of  O₂ = 0.130 mol

Volume = 1.50 L

[O₂] = x = 0.0867 M

[SO₂] = 2x = 0.1733 M

[SO₃] = 0.5067-2x = 0.3334 M

The expression for the equilibrium constant is:

answer is: nuclear fusion produces elements that are heavier than helium.

nuclei combine to form a heavier nucleus, releasing energy.  

for example, fusion of hydrogen atoms at the sun.  

this fusion nuclear reaction is in the inner core of the sun and hydrogen (atomic number 1) is conveted into helium (atomic number 2).  

the inner core is the central region of the sun and all solar energy is produced in the core by nuclear fusion.
