black coffee has a pH of 5, therefore its H+ concentration is ______ times greater than a solution with a pH of 10.
Tju [1.3M]

Answer:

100,000

Explanation:

pH of coffee = 5

pH of solution = 10

Concentration of H+ ions between successive pH values are in multiples of 10

Hence, the pH difference :

pH of solution - pH of coffee

(10 - 5) = 5

Hence, difference in H+ ions will be :

10^5 = 10*10*10*10*10 = 100,000 times

Paraphin [41]
<h2>Answer:</h2>

The priority list will be like this

  1. Fruit Trees
  2. Birds
  3. Monkeys
  4. Tigers
<h2>Explanation:</h2>

In an ecosystem, producers are the first level of the food chain. And we know that plants are producers because they produce their own food. So, fruit trees will be at the beginning of the food chain. After producers comes the primary consumers. Primary consumers are animals that feed on producers. Both birds and monkeys feed on fruit trees, so they are the next in line after fruit trees. Finally, secondary consumers eat primary consumers. As tigers eat animals i.e monkeys etc so they are secondary consumers, and thus they are last on the food chain list.
