Q: Answer the following question given this paragraph: As base is added to acid at the beginning of a titration, the pH rises very slowly. Nearer to the equivalence point, the pH begins to rapidly increase. If the titration is a strong acid with a strong base, the pH at the equivalence point is equal to 7. A bit past the equivalence point, the rate of change of the pH again slows down. A titration curve is a graphical representation of the pH of a solution during a titration. The Figure below shows two different examples of a strong acid-strong base titration curve. On the left is a titration in which the base is added to the acid and so the pH progresses from low to high. On the right is a titration in which the acid is added to the base. In this case, the pH starts out high and decreases during the titration. In both cases, the equivalence point is reached when the moles of acid and base are equal and the pH is 7. This also corresponds to the color change of the indicator. Q: What's the name for the point reached at a ph of 7? Choices: - analogous point - acidic point - constriction point - equivalence point A:
A: equivalence point

Q: Answer the following question given this paragraph: Three ways electrons can be transferred are conduction, friction, and polarization. In each case, the total charge remains the same. This is the law of conservation of charge. Q: Which law refers to the electron charge remaining the same during transfer? Choices: - law of construct of charge - law of change - law of conservation of speculation - law of conservation of charge A:
A: law of conservation of charge

Q: Answer the following question given this paragraph: Scientists use the geologic time scale to illustrate the order in which events on Earth have happened. Q: Scientists use what scale to illustrate the order in which events on earth have happened? Choices: - ecological succession - fossil record - cataclysmic time scale - geologic time scale A:
A: geologic time scale
