Answer:
The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Along with the nitrogen cycle and the water cycle, the carbon cycle comprises a sequence of events that are key to make Earth capable of sustaining life.
Explanation:
Answer:
Mass of hydrogen = 667 kg (Approx)
Explanation:
Given:
Mass of water = 593 kg
Yield rate = 88.9%
Find:
Mass of hydrogen
Computation:
Mass of hydrogen = [Mass of water / Yield rate]100
Mass of hydrogen = [593 / 88.9]100
Mass of hydrogen = 667.04162
Mass of hydrogen = 667 kg (Approx)
