How much more [H+] does lemon juice (pH 2) have compared with pure water (pH 7)? Remember that each pH unit represents a 10 fold

zhenek [66]

Answer:

$10^5 \\or\\100,000$

Explanation:

As we know that the formula for pH is

$pH = -[log H+]\\$

It is also given in the question that one pH unit represents the 10 fold change in the concentration of hydrogen ion.

Now for lemon juice whose pH is 2, hydrogen ion concentration is equal to

$10^-2\\= \frac{1}{100}$

And for pure water whose pH is $7$ , hydrogen ion concentration is equal to

$10^ -7\\= \frac{1}{10000000}$

Thus, the H+ ion concentration in lemon juice is $10^5$ times greater than the pure water.

Why are xylem vessels more efficient in the transport of water than tracheids

Paha777 [63]

Explanation:

The vessels of the xylem are more efficient than the tracheids in water conduction due to the presence of perforations in them. These perforations allow for the continuous flow of water into the xylem vessels.The xylem tracheids are long, narrow, tubelike cells. The walls of tracheids are thick and hard.
