Answer:
3
Explanation:
You have to mutiply the silver reaction by 3 in order to substract the electrons
More collisions occur making the particles used up
The interaction between the two atoms of H in H2 with the lower energy corresponds to a covalent bond between hydrogen's.
When the two atoms of H form a bond, they are overlapping the individual orbitals to form a new one. Every hydrogen has 1 electron which sits in a 1s orbital and then form one molecular orbital. The energy of H2 is lower than individual hydrogens because the electrostatic interaction between them.
Explanation:
2FeS + 7/2O2 ---> Fe2O3 + 2SO2
