Solve Neutralization Problem: H ion Concentrations & Final pH

AI Thread Summary
To determine the final pH after mixing two solutions with different H ion concentrations, one must first calculate the total moles of H ions in each solution. The first solution has 3x10^-2 M H ion concentration, while the second has 10^-12 M. After mixing, the total volume becomes 200 ml, and the final concentration of H ions can be found by adding the moles from both solutions and dividing by the total volume. Understanding the concept of neutralization and the definition of pH is crucial for solving this problem. The final pH can then be calculated using the formula pH = -log[H+].

Homework Statement



We have a solution of 1oo ml and the concentration of H ion is 3x1o^-2 M.
We have another solution of 100 ml and the H ion concentration is 10^-12 M.

After mixing the solutions,what would be the pH of the final solution?

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...
