Problem: OPTIONS:
- analogous point
- acidic point
- constriction point
- equivalence point
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? A:
Answer: equivalence point

Problem:OPTIONS:
- a and b

Answer the following question given this paragraph: There are two main types of air pollutants: primary and secondary. Most air pollutants come from burning fossil fuels. Some come from burning forests. Some are due to the evaporation of chemicals. Q: What are the two main types of air pollutants? A:
****
A: primary and secondary

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? A:
OPTIONS:
- law of construct of charge
- law of change
- law of conservation of speculation
- law of conservation of charge
law of conservation of charge

Answer the following question given this paragraph: A uniform electric field makes it easier to measure the difference in electric potential energy. This energy, also called the electric potential difference is commonly referred to as the voltage , based on the unit, volt (V). To measure the voltage across some distance, it is necessary to pick a position to be the relative zero, because voltage is the change in potential difference. Any point in a system can be given the value of zero volts, but it is typically the point of a point charge or one plate in a uniform electric field as shown above. The voltage is measured using a voltmeter, which measures the electric potential difference across two points. Q: The voltage is measured using a voltmeter, which measures which difference across two points? A:
OPTIONS:
- Distance
- actual difference
- average difference
- potential difference

Answer: potential difference

Question: Answer the following question given this paragraph: Electron Configurations of Ions We have seen that ions are formed when atoms gain or lose electrons. A cation (positively charged ion) forms when one or more electrons are removed from a parent atom. For main group elements, the electrons that were added last are the first electrons removed. For transition metals and inner transition metals, however, electrons in the s orbital are easier to remove than the d or f electrons, and so the highest ns electrons are lost, and then the (n 1)d or (n 2)f electrons are removed. An anion (negatively charged ion) forms when one or more electrons are added to a parent atom. The added electrons fill in the order predicted by the Aufbau principle. Q: Ions are formed when atoms gain or lose what? A:
OPTIONS:
- mass
- protons
- neutrons
- electrons
Answer: electrons
