Expert Solution & Answer
Answer to Problem 2.54QA
Solution:
(a) CH4: The number of hydrogen atoms is 4.
(b) C3H8: The number of hydrogen atoms is 8.
(c) C6H6: The number of hydrogen atoms is 6.
(d) C6H12O6: The number of hydrogen atoms is 12.
Explanation of Solution
1 mole = 6.022*1023 molecules.
a) CH4 – Here we can use Avogadro’s number as a conversion factor to calculate number of hydrogen atoms in 1 molecule of CH4.
(b) C3H8 - Here we can use Avogadro’s number as a conversion factor to calculate number of hydrogen atoms in 1 molecule of C3H8.
(c) C6H6 - Here we can use Avogadro’s number as a conversion factor to calculate number of hydrogen atoms in 1 molecule of C6H6.
(d) C6H12O6 - Here we can use Avogadro’s number as a conversion factor to calculate number of hydrogen atoms in 1 molecule of C6H12O6.
Conclusion:
The number of hydrogen atoms can be calculated by using Avogadro’s number.

In a cell, the change in entropy (AS) can be calculated from the slope of the E° vs
1/T graph. The slope is equal to -AS/R, where R is the gas constant. Is this correct?
Using the Arrhenius equation, it is possible to establish the relationship between the rate constant (k) of a chemical reaction and the temperature (T), in Kelvin (K), the universal gas constant (R), the pre-exponential factor (A) and the activation energy (Ea). This equation is widely applied in studies of chemical kinetics, and is also widely used to determine the activation energy of reactions. In this context, the following graph shows the variation of the rate constant with the inverse of the absolute temperature, for a given chemical reaction that obeys the Arrhenius equation. Based on the analysis of this graph and the concepts acquired about the kinetics of chemical reactions, analyze the following statements:
I. The activation energy (Ea) varies with the temperature of the system.
II. The activation energy (Ea) varies with the concentration of the reactants.
III. The rate constant (K) varies proportionally with temperature.
IV. The value of the…

- The environmental police of a Brazilian state received a report of contamination of a river by inorganic arsenic, due to the excessive use of pesticides on a plantation on the riverbanks. Arsenic (As) is extremely toxic in its many forms and oxidation states. In nature, especially in groundwater, it is found in the form of arsenate (AsO ₄ ³ ⁻ ), which can be electrochemically reduced to As ⁰ and collected at the cathode of a coulometric cell. In this case, Potentiostatic Coulometry (at 25°C) was performed in an alkaline medium (pH = 7.5 throughout the analysis) to quantify the species.
