Question
Chapter 11, Problem 15E
Interpretation Introduction
Interpretation:
The cycles that carbon atoms go through, are to be explained. The number of such cycles formed by an average carbon atom is to be determined.
Concept Introduction:
The earth stores carbon in rocks, fossil fuels, oceans, the atmosphere, plants, as well as in the soil. This carbon is changed within its reservoirs in a biogeochemical cycle called the carbon cycle. It is through the carbon cycle that carbon is recycled among the biosphere and its organisms, and this occurs via slow and fast components.
Carbon is exchanged slowly within soil, rocks, ocean, and atmosphere via

In experiment #7, you observed the formation of carbon dioxide by reacting baking soda with vinegar. Why was it not possible to relight the candle?
A. Carbon dioxide is heavier than air so it stays in the beaker preventing the candle from relighting.
B. Carbon dioxide is lighter than air so it escaped from the beaker and the candle should have relit.
C. Carbon dioxide is heavier than air so it stays in the beaker and the candle should have relit.
D. Carbon dioxide is lighter than air so it escaped from the beaker preventing the candle from relighting.

PCI,(g) 2 PCI;(g) + Cl2(8)
PCI,(g) decomposes into PCI,(g) and Cl,(8)
according to the equation above. A pure sample of
PCI,(g) is placed in a rigid, evacuated 1.00 L
container. The initial pressure of the PCI5(g) is
1.00 atm. The temperature is held constant until
the PCI,(g) reaches equilibrium with its
decomposition products. The figures below
show the initial and equilibrium conditions of the
system.

reverse reaction rate at equilibrium
(B) stays constant before and after equilibrium is
reached

When detonated by a spark, AND rapidly decomposes to produce a gaseous mixture of N2,O2, and H2O. (This is not a combustion reaction. The ADN is the only reactant.) The reaction releases a lot of heat, so the gases are initially formed at high temperature and pressure. The thrust of the rocket results mainly from the expansion of this gas mixture. Suppose a 2.3-kg sample of ADN is denoted and decomposes completely to give N2,O2, and H2O. If the resulting gas mixture expands until it reaches a temperature of 100°C and a pressure of 1.00 atm, what volume will it occupy? Is your answer consistent with the proposed use of ADN as a rocket fuel?arrow_forward
