Answer: 0.0001M

Explanation:

Given that:

[H₃O⁺] (hydronium concentration) = ?

pH of aqueous solution = 4.00

pH is the negative logarithm of hydrogen ion [H+] or hydroxonium ion [H₃O⁺] in a solution. Mathematically it is expressed as:

pH = -log[H₃O⁺]

4.00 = -log[H₃O⁺]

[H₃O⁺] = Antilog (-4.00)

[H₃O⁺] = 0.0001M

Thus, 0.0001M is the [H₃O⁺] (hydronium concentration) of an aqueous solution that has a pH of 4.00

saul85 [17]

Astronomy

Geology

Environmental science

Explanation:

The study of the space around earth and the universe including meteoroids and galaxies that are trillion of miles away is called astronomy.

Astronomy has involves the study of everything in the universe. What started off as monitoring of star positions now uses sophisticated telescope and spacial probes to obtain information about the expanding universe.

Geology is a science that studies the earth rocky surface to determine when and how the earth formed and how its surface is constantly changing.

Our blue planets is a dynamic celestial body. Geology combines different disciplines like physics, biology, chemistry e.t.c to make meaning of the earth.

Environmental science is the study of complex interactions taking place between living organisms and earth's non-living systems.

It simply implies the interaction between living organisms and their environment.
