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

A cat standing near a pond looking at the fish in water. Which of the following statement is correct?
salantis [7]

Answer:

The fish appears nearer to the cat than it really is

Explanation:

The situation above is related to the refraction of light. The cat will think that the fish is closer to him, however, it is actually at a<u> different depth</u> in its<em> actual position</em>. This is because of the refraction of light as it travels in two different mediums: <em>water and air.</em> The eyes and brains are<u> not capable of tracing the light rays' refraction,</u> thus, the cat's image of the fish is on a shallower depth. In reality, the light rays reflecting from the fish are actually being refracted on the water's surface.
