A buffer is a solution that can resist pH change upon the addition of an acidic or basic components. It is able to neutralize small amounts of added acid or base, thus maintaining the pH of the solution relatively stable. This is important for processes and/or reactions which require specific and stable pH ranges. Buffer solutions have a working pH range and capacity which dictate how much acid/base can be neutralized before pH changes, and the amount by which it will change.
I think it might be Nitrogen dioxide, but please check behind
I think during toddler years, I used to be sooo paranoid during that time because I used to think about robbery, etc.
6.4 times 10^-7 is the answer because you are moving your decimal places to the left so it will be negative 7
