The pH of a solution is measured eight times by one operator using the same instrument. She obtains the following data: 7.15, 7.
sergiy2304 [10]

Answer:

7.186

Explanation:

The mean is the average of some given data from a sample point.

To calculate the mean, we use the formula below:

             Mean = ∑fx/∑f

Where f = frequency

           x = sample data

   

From the given pH of the solutions, we can form a table:

      x                                     f                                          fx

    7.15                                  1                                         7.15

    7.16                                  1                                         7.16

    7.18                                  1                                         7.18

    7.19                                  1                                         7.19

    7.20                                 3                                        21.6

    7.21                                  1                                         7.21

Now ∑fx = 7.15 +7.16 +7.18 + 7.19 + 7.20 + 7.21 = 57.49

         ∑f = 1 + 1 + 1 + 1 + 3 + 1 = 8

The mean = \frac{57.49}{8} = 7.18625 = 7.186

When a suspension of algae is incubated in a flask in the presence of light and CO2 and then transferred to the dark, the reduct
Aloiza [94]

Answer:

The photosynthesis process is interrupted.

Explanation:

Algae produce energy using the photosynthesis process. The reduction of 3-phosphoglycerate to glyceraldehyde 3-phosphate is part of this process. Despite this reduction reaction being light-independent (Calvin Cycle), the precursors of this reaction are synthesized in light-dependent steps.

This is the reason why the reduction is blocked when the algae is placed in the dark.

Sakura tested the ph of several solutions. which substances are acidic? check all that apply. cola-flavored soda: 2.6 cranberry
Step2247 [10]

Answer:- Cola-flavored soda:2.6, cranberry juice:2.9 and pickle juice:5.5 are acidic.

Explanations:- As per the pH scale, the solution is acidic if the pH is below 7 and the solution is basic if the pH is above 7. The solution is neutral if the pH is exactly 7.

There are only three solutions with pH value below 7 and so they are acidic. these three solutions are, cola-flavored soda, cranberry juice and pickle juice.

Rest of them are basic as their pH value is greater than 7.
