No, to make it neutral you would have to add OH ions. Water will dilute it and make it less acidic, but it still will be an acid.
Math
Simple interest is just: Interest = Principle x rate x time be sure to write % as a decimal to 5% = .05 and 3% = .03 You can add your interest to the original value to find the future value. Compounded annually: Future value = P(1+ rate)^time tiffany's problem: Future valu...

Then you just have to multiply 2400 x .105 x 1.5
Math
Did you mean find the simple interest? If so... here is the method to use. Interest = Principle x Rate x time P = 2400 R = 10.5% use .105 in the formula T = 1.5
Physics
V= IR in this case V = I(R1+R2) so we have 15 = IR1 + IR2 (15 - IR1)/I = R2 we will use this later in our subsitution. We also know that... 15 =(I+.05)R1 and 15 = (I+.025)R2 since both equal 15, they must equal each other: (I+.05)R1 = (I+.025)R2 Use the substitution for R2 fro...

I don't see your function.
Geology
I think it is by the fossils found in rock strata.
Earth Science
Now, I think it might be Potassium.. I just saw anothr post with K -40 has a half life of approx. 1.25 billion years.
Earth Science
You want a long half-life for older rocks. I think it may be argon, but you need to lookup the half-lives of each of them. You can probably google it.
physics
A - B = +5 A - C = -16 Do between B-C we must have -21
