1. What is the concentration of OH- ions in saturated limewater if [H3O+] = 3.98 × 10-13 M? Is limewater acidic, basic, or neutral?
2. What is the concentration of OH- ions in a potato and water solution if [H3O+] = 1.6 × 10-6 M? Are potatoes and water acidic, basic, or neutral? 3. Analysis of a sample of maple syrup reveals that the concentration of OH- ions is 5.0 × 10-8 M. What is the pH of this syrup? Is it acidic, neutral, or basic? 4. In a sample of bananas and water, it is found that [H3O+] = 2.51 × 10-5 M. What is the corresponding pH value, and are the bananas and water acidic, neutral, or basic? 5.[OH-] = 7.94 × 10-12 M in a sample of vinegar.

I have an Eaton Cutler-Hammer meter/breaker box. (MB816B200BTS-FLCH) I want to run a 20 amp circuit (underground wire) from this box through existing underground conduit to a receptacle for a dishwasher. This run would be app. 15' to 20' and from my main house panel it would be 40' to 50'. All...
The same conect some grounds and neutrals to the ground bus bar just using whichever bus bar is closest to the breaker so the wires don't have to travel all around the breaker box is that OK and safe to connect wires like that thank you
