In the contact process, sulfuric acid is manufactured by first oxidizing SO2 to SO3, which is then reacted with water. The react
ion of SO2 with O2 is
2SO2(g) 1 O2(g) m 2SO3(g)
A 2.000-L flask was filled with 0.0400 mol SO2 and 0.0200 mol O2. At equilibrium at 900 K, the flask contained 0.0296 mol SO3. How many moles of each substance were in the flask at equilibrium?

Answer:
PROTON AND NEUTRON
Explanation:
- The mass of proton is :
A proton is one of the main particles that make up the atom . The other two particles are neutron and electron. Protons are found in the nucleus of the atom.This is a tiny , dense region at the centre of the atom. Protons have a positive charge of one (+1) and a mass of 1 atomic mass unit ( amu ) , which is about . Together with neutrons , they make up virtually all of the mass of an atom.
- The mass of neutron is also approximately:
but a little more than that .
Atoms of all elements - except Hydrogen , have neutrons in their nucleus . Unlike protons and electrons , these have no charge - they are electrically neutral . The mass of a neutron is slightly greater than the mass of a proton but not very significant
