Explanation:
Answer:
Initial concentration of acetic acid (CH3COOH_initial): 0.25 M
pKa for acetic acid: 4.76
Assume x is the concentration of H+ ions formed through dissociation.
CH3COOH ⇌ x (due to dissociation)
Apply the x-is-small approximation: We assume x is much smaller than the initial concentration of acetic acid (0.25 M). Therefore, we can neglect x in comparison to 0.25 M.
Calculate pH using the pKa equation:
Rounded to two decimal places, the pH of the acetic acid solution is approximately 2.68.

Answer:
Improving the habitats of herring thereby increasing their population.
Explanation:
First, two consumers (Steller sea lion and Pollock) are both competing for common prey (herring). Since the question only asked what could be done to increase the decreasing Steller sea lion population of Alaska, the focus would be made only on the Steller sea lion.
The Steller sea lion population would increase if:
1. The herring population should be increased by improving the food available for them to feed on, and improving their reproduction capacities to enable them to reproduce efficiently.
2. Since there are 2 predators. If the population of the prey is fixed, then Pollock should be more hunted by farmers or other biological means to eliminate competition.

The water molecules slow down, stronger attractions form between them, and the molecules stop flowing around.
The water molecules speed up, attractions between them become weaker, and the molecules spread out.
The water molecules speed up, new bonds are formed, and the new molecules are pulled closer together.
Answer:
The water molecules slow down, stronger attractions form between them, and the molecules stop flowing around.
Explanation:
imagine how the solids (so ice) are structured: atoms are very close to each other and vibrate on the spot.
