What chemically happens to someone's brain when they lose their dominate arm?
Does nothing change or do they slowly change their brains dominate side as they learn new tasks. If this is the case does that mean that you could do the same thing without losing an arm by first eating or opening bottles with your non dominate arm then working up to writing and change your handedness or becoming ambidextrous?

It wouldn't be a chemical issue. The situation you describe would be the brain rewiring itself in response to a loss of nerves somewhere in the body. I'm no expert, but I have a guess based on psychology and biology classes I've taken. It makes sense that the brain rewires as some neural networks are lost-- a property called plasticity. This is seen in a recovering stroke patient-- the brain changes physically to accommodate for death of a certain brain region. So maybe the brain rewires to make the non-dominant arm functional.
There is one thing I know for sure. When people lose a limb, they may still feel the pain. There's a condition called phantom limb, which means that the person feels the lost limb as though it is still there, and it feels like it is on fire. Sorry, kind of went on a tangent
