Chemistry I Spring semester 2011

2. So what exactly is
CO2?
Carbon Dioxide is composed of one
Carbon atom and two Oxygen atoms
Natural CO2 Emissions Man-Made CO2 Emissions
Forest Fires Industrial Plants
Volcanoes Power Plants – used to create energy
Vehicles (main source) 13%
Aerosol Sprays, Paint, varnish, & other
solvents
Livestock Farming 18%

3. So how much Item 1950-59 1960-69 1970-79 1980-89 1990-99 2000
meat do I
eat? Total

4. How does CO2
affect the
Ocean?
Our oceans absorb almost half
of all CO2 emissions and the
abnormal man-made emissions
are causing high levels of
acidity making it hard for
marine life to thrive.
Slowed growth of plankton,
corals, and other invertebrates
Has led to high levels of anoxia
in our oceans, the Gulf of
Mexico being the second
highest anoxic ocean in the
world

5. How is CO2 detected in H2O?
In chemistry, limewater can
be used to detect the
presence of carbon dioxide
because lime water reacts
with carbon dioxide to
produce a precipitate of
calcium carbonate:
Ca(OH)2 (aq) + CO2 (g)
→ CaCO3 (s) + H2O (l)
•Carbon dioxide turns lime
water milky

6. So why should I
care, it does not
affect me!
If we continue to pollute
the air we breathe and the
oceans, we will begin to
see a direct effect on
human health.
air pollution could cause
about a thousand additional
deaths and many more
cases of respiratory illness
and asthma in the United
States.

7. How can we preserve our oceans for
future generations?

8. Reduce CO2!

9. Get a fuel efficient vehicle

10. Eat less meat

11. Paint a rooftop white

12. How would something so simple help
reduce CO2 levels?

13. Plant a tree

14. Reduce, Reuse, Recycle
Volunteer at your local recycling center
