How many times a day was the experiment in Passage 5 done for 12 months?

• Once a day

• Twice a day

Based on Figure 2 and Table 1, during the month in which a total of 70 L of H₂ was produced, the average solar irradiance was:

• 77.8 W/m²

• 153.8 W/m²

• 197.5 W/m²

• 206.4 W/m²

Based on the description of the experiment, at 4:00 pm on each day, did the scientist measure the amount of gas produced at the anode or the cathode?

• The anode, because the anode is where H₂ was produced.

• The anode, because the anode is where O₂ was produced.

• The cathode, because the cathode is where H₂ was produced.

• The cathode, because the cathode is where O₂ was produced.

NGSS.MS-PS1-5

Based on Table 1, on May 11, was the solar irradiance of the solar cell less than, equal to, or greater than 197.5 W/m²?

• Less

• Equal

• Greater

• Cannot be determined from the given information

Suppose the experiment was repeated, except that the scientist added only pure liquid H₂O to the task in Step 2, Based on the description of the experiment, would this change have more likely resulted in more H₂ being produced or less H₂ being produced?

• More H₂; pure liquid H₂O has more ions and thus higher electrical conductivity than does an aqueous NaOH solution.

• More H₂; pure liquid H₂O has fewer ions and thus lower electrical conductivity than does an aqueous NaOH solution.

• Less H₂; pure liquid H₂O has more ions and thus higher electrical conductivity than does an aqueous NaOH solution.

• Less H₂; pure liquid H₂O has fewer ions and thus lower electrical conductivity than does an aqueous NaOH solution.

Consider the percent by mass of NaOH in the solution add to the tank of Step 2. Approximately what mass of NaOH was in 200g of this solution?

• 25g

• 50g

• 200g

• 225g

NGSS.MS-PS1-5

Based on the description of the experiment, is the month of June how many total liters of NaOH solution were added to the tank?

• 4.0 L, because Step 2 was performed once in June, on June 1.

• 8.0 L, because Step 2 was performed twice in June, once on Jun 1 and once on June 30.

• 120 L, because Step 2 was performed 30 times in June, once each day.

• 240 L, because Step 2 was performed 60 times in June, twice each day.

What type of passage is passage 5?

• charts and graphs

• experiment

• opposing viewpoint
