Answer:
3 moles of carbon, 3 moles of hydrogen and 1 mole of oxygen
In pure water, the concentration of hydronium ions, or H⁺, will equal the concentration of hydroxide ions. That is [H⁺] = [OH⁻].
Remember that Kw = [H⁺][OH⁻] for water and if [H⁺] and [OH⁻] are both equal, we can easily solve for them by taking the square root of Kw.
[H⁺] = [OH⁻] = sqrt(1.47*10^-14) = 1.21*10^-7
The concentration of hydroxide ions at 30 degrees Celsius is 1.21*10^-7

Answer:
the tilt of the Earth and its orbit around the Sun.
Explanation:
The seasons on the earth is as a result of the tilt of the earth and its orbit around the sun.
These phenomenon causes the four seasons of the earth. The earth is tilted at an angle of 23.5° from the perpendicular.
This causes the differences in yearly exposure of parts of the earth to solar radiation.
At some points, a part can experience very high insolation whereas it is low in other parts.
These variations results in the seasons on the earth.
