Answer:
D) The product of two rational numbers is rational.
PH is a parameter that tests the acidity or basicity of a substance or a solution. In this case, the formula to be followed is pH = –log[H+]. To get the H+ concentration from the pH, we manipulate the equation by raising both sides by the base of 10. Thus, 10^ -pH = H+. with pH of 7.2, thus the answer to this problem is C<span>[H+] = 10^-7.2</span>
Answer:
286.5 degrees
Step-by-step explanation:
We want to change radians to degrees
2 pi radians = 360 degrees
5 radians * 360/ 2 pi
900/pi degrees
286.4788976 degrees
286.5 degrees
