Answer:
B
Explanation:
the pH scale is based on the function
1x10-14
So since pH is neutral the concentration of OH and H must be equal hence the only option in which the concetration would [OH]{H}= 1x10-14 would be when both are equal so it cannot be a or d and when they are expressed in concetration so the only option is B.
1. 100.67
2. 168.55
3. 2.747
So I’m not sure if 2 or 3 are right sorry
Increase, because you need heat to melt a solid to a liquid, so the temperature will have to get greater.
Se2- has 34 protons and 36 electrons so it gets a 2- charge.
