If two conducting spheres are separately charged and then brought in contact

What a will happen if two conducting spheres are separately chargedand then brought in contanct ?

Two spheres are separately charged and then brought in contact, so

Charged Conducting Sphere

Two identical conduction spheres, one having an initial charge +Q and the other initially uncharged, are brought into contact. (a) What is the new charge on each sphere? (b) While the spheres are in contact, a positively chaged rod is moved close to one sphere, causing a redistribution of hte charges on the two spheres so the charge on hte sphere closest to the rod has a charge-Q. What is the charge to the other sphere?

There are two identical spheres A and B. Now charge Q is established on each sphere. There is a third identical neutral sphere C. Now sphere C is first brought in contact with A and separated then brought in contact with B and separated. After this what will be charge on C ?

Two identical conducting spheres are charged by induction and then separated by a large distance, sphere 1 has charge +Q and sphere 2 has charge -Q. A third sphere is initially uncharged. If sphere 3 is touched to sphere 1 and separated and then touched to sphere 2 and separated what is the final charge on each of the three spheres?
