AI Thread Summary
The chemical equation Al(OH)4-(aq) + H2SO4(aq) ---> Al(OH)3(s) + H2O + SO4^2- needs balancing, particularly for oxygen and charge. The initial attempt suggests adding 3/2H2O, but this does not fully address the imbalance. It is noted that Al(OH)4- loses OH- while H2SO4 loses 2H+, indicating further adjustments are necessary. To achieve balance, one should focus on both the number of atoms and the overall charge in the equation. Properly balancing this equation will require careful consideration of these factors.

Homework Statement
I am to balance the following equation:
Al(OH)41-(aq) + H2SO4(aq) ---> Al(OH)3(s) + H2O + SO42-

The attempt at a solution

Al(OH)41-(aq) + H2SO4(aq) ---> Al(OH)3(s) + 3/2H2O + SO42-

The bolded part above is all I could add to the equation, but I now need to balance the oxygen. This is where I am stuck. Any help is appreciated.

It is not only oxygen, there are more problems with the equation - charge is not balanced.

Al(OH)4- loses OH-, H2SO4 loses 2H+. Try to start from here.

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...
