Some consequences of Climate change are:
(Choose only 3)
Changes in ecosystems and desertification.
Increase of clean water for people.
Acidification of the ocean.
Extreme weather events.
More food production.
The formula that represents the Ocean Acidification is:
(Ninguna que se vea como "Ca Ca" es correcta)
O2 + Ca = CaO3
CO2 + H2O = H2CO3
HCO + H = H2CO
CO3 + Ca = Ca CO3
The ocean acidification is caused by the CO2 when it has contact with the H2O of the ocean water.
True
False
The PH calculates the level of _______ in a substance.
Oxygen
Hydrogen
Helium.
Nitrogen
The name of this molecule: H2CO3, is:
Carbon dioxide.
Calcium carbonate.
Carbonic acid.
Methane
Among the most threatened marine species (due to ocean acidification) we have:
snails, algae, corals, fish
sharks, jellyfish, seals, polar bears.
sardines, starfish, oysters
corals, crabs, lobsters, clams and oysters.
