Question
Chapter 4.9, Problem 4.30YT
Interpretation Introduction
Interpretation:
The amount of carbon dioxide is Earth’s atmosphere is increasing; the reasons behind this has to be listed out.
Concept introduction:
- Ø Global warming is a serious environmental issue, in which there is an increase in the overall temperature of the earth by various factors.
- Ø Greenhouse gases are one type of gas which traps the heat within the system and thus it increases the overall temperature of the earth resulting global warming.
Examples:
- Ø Greenhouse effect: The heat near the earth surface gets trapped by the gases present in the earth atmosphere. The carbon dioxide is the primary gas that traps more heat.
- Ø Atmosphere: The atmosphere is defined as air that is layer of gases which surrounds the earth due to gravity of earth.
- Ø The earth atmosphere consists of layers such as thermosphere, mesosphere, stratosphere and troposphere depending on the temperature and its composition.

19. The chemical equation for photosynthesis is
_CO2 (g) + _H₂O (1)→ __C6H1206 (s) +
(C6H12O6 is glucose, the simplest sugar)
a. Balance the chemical equation above by filling in the blanks.
b. According to onetreeplanted.org, the average tree (across all climates and sizes) removes 10 kg of
carbon dioxide from the atmosphere every year. Based on this, what mass of glucose is produced
annually by the average tree?
O2 (g)
c. Teak is a common species of tropical tree. The graph below shows the amount of CO₂ absorbed by teak
forests in tons of CO₂ per hectare of forest per year, according to the climate region where the forests
are found (dry = low rainfall, humid=high rainfall). Looking at your photosynthesis equation again, what
does this data suggest about which reactant is the limiting reactant for teak trees? Explain.

Part 1
A student carried out an investigation to observe the effect of changing
concentration of sulfuric acid on the breakdown of calcium carbonate
(marble) chips. They changed the concentration of the acid between
each test but kept the size of the marble chips constant. The full equation
for the reaction and a graph of the overall results can be seen below.
CaCO3(s) + H₂SO4(aq) → CaSO4(aq) + CO2(g) + H₂O (1)

Explain, using collision theory, why the student obtained
these results, and state what they could conclude about the
effect of changing concentration of acid on the rate of reaction
between calcium carbonate and sulfuric acid.
If the student had ground up the calcium carbonate chips into
a powder and run the tests again, what would you expect to
happen to the rate of reaction? Briefly explain why by
applying collision theory.
Part 2
