In early spring, many wildflowers begin to grow, produce flowers, and release seeds. The leaves of the wildflowers make food before the leaves of the trees in the area begin to develop. The early growth pattern of the wildflowers would likely result in decreased competition for sunlight between the trees and the wildflowers (1). There is a good reason why the wildflowers grow so much earlier than the trees. If they start growing at the same time in spring, then the tree leaves will block out the sun for the wildflowers.

What is the pH if 20 mL of pH = 2 solution is diluted to a final volume of 600 mL?

Mashutka [201]

Explanation:

Hydrogen atoms contain 1 proton and 1 electron while being devoid of neutrons. When they lose their electron they form an ion or H+, a particle carrying a unit of positive charge. pH measures how basic or acidic a water-based solutions are, with a formula for pH is

pH = -log[H+].

...where pH is -base 10 log of the concentration of hydrogen ions within the solution.

Initial volume= 20 mL

Final volume= 600 mL

# of dilutions= $\frac{600}{20}$ = 30
