Ocean Acidification

According to this slide

• CO₂ is causing marine life to die by "poisoning' the water

• CO₂ is destroying sea shells

• CO₂ is formed from the combustion of Octane

According to this slide the final products of the reaction HCO₃^- & H⁺. Which are products from

• CO₂ is synthesizing with H₂O

• CO₂ is reacting with marine life

• CO₂ is reacting with O₂

According to the slide which of the following is not a solution for reducing CO₂ emissions

• Renewable sources of energy like wind

• Carbonate is important for building coral reefs

• Public transportation

What is the importance theme of this slide?

• The acidification of our ocean will benefit some organisms over others

• The acidification of our ocean will hurt all organisms

• The main source of CO₂ is our factories.

This heat map of the Atlantic Ocean shows the concentration of dissolved salts in the ocean.

• Therefore salt is collecting at the deepest parts of the ocean

• Therefore the ocean is warmest when it is farther away from land

• Therefor the salts are not dissolving in the blue areas

What are factors that explain why Brazil and southern Africa have lower CO₂ emission

1. Presence of forests
2. Less factories and cars
3. Cooler temperatures

• 1 and 3

• 1 and 2

• 1 only

This image demonstrates that

• There is a direct correlation with the atmospheric CO₂ and the CO₂ in seawater

• That pH of the ocean increases as the atmospheric CO₂ increases

• That there is no correlation between pH of the ocean and atmospheric CO₂

A common "Antacid" would be Tums or Rolaids. These are "anti-acids", which we take when we have too much acid in our stomachs. Therefore Antacids must be made from

• bases

• O₂

• neutral water

According to the law of conservation of matter H₂O combines with CO₂ to form

• H₂CO₃

• CO

• O₃

During the lab to perform a serial dilution to make 50mL of 1.0M acid to 0.10M acid what was the ratio of acid to water?

• 1:9

• 3:30

• 5:50
