AI Thread Summary
The reaction Au2(SO4)3 + Ba involves balancing the equation and determining its type. It is suggested that barium replaces gold, indicating a single displacement reaction. The reaction is classified as a redox reaction, with barium being oxidized and gold being reduced. To analyze the reaction further, half-cell reactions for Au+3 and Ba should be written, treating sulfate as a spectator ion. Understanding these concepts will clarify the reaction dynamics and balance.

If the reaction does occur (I don't have the electric potentials of Au and Ba handy) it is indeed a redox reaction. Barium replaces gold...

Write out the half cell reactions for Au+3 and Ba and go from there. Treat the sulfate as a spectator ion.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
