Now, there’s many kinds and levels of AI, and people confuse these and conflate them. The first kind of AI is just computers doing stuff that we try to do in our minds, like calculate what a parabola is, how fast a car is going to go, or how much money a bus...
2. How do you calculate pH and pOH?Describe the pH scale. What is it measuring?What is the effect of buffers on pH? How does it work?How do you know which one would have the lowest pH or the highest pH?What does the pH measure?
The concentration of ions in a solution is defined by the number of ions in grams present per litre of that solution. Concentration is mainly explained in terms of molarity. We can calculate concentration by multiplying the molarity and volume of the solution....
