The concentration of hydrogen ions in a water-based solution is key to finding out its pH, which tells us how acidic or basic it is. The relationship between pH and hydrogen ion concentration is given by the equation pH = -log[H+]. In this experiment, if the concentration of hydrogen ions [H+] fits the equation log[H+] + 2 = log(3 × 10⁻⁵), what will be the pH of this solution?a.
The pH of this solution is 6.52.
b.
The pH of this solution is 5.52.
c.
The pH of this solution is 7.48.
d.
The pH of this solution is 6.00.
e.
The pH of this solution is 8.25.

In an electrical engineering context, we represent the impedances of two circuit components with complex numbers. If the impedance of the first component is Z₁ = 20 + 15i Ω and the second one is Z₂ = 10 - 5i Ω, what is the real part of the total impedance for these components connected in series?
