The overall order of a reaction is directly
related to the reaction mechanism of the reaction. The reaction mechanism is
defined by the reaction rate equation. In this case, we are given by the
equation, Rate=k. The order of this reaction is zero since the rate is
not dependent on the concentration of reactants or products.
Answer:
Washing hands with soap and water. Sanitizers are only used if there is no soap and water.
Answer:
See explanation and images attached
Explanation:
We know that the cis isomer has more heat of hydrogenation since it is less stable than the trans isomer. Since the hydrogenation of both compounds yields the same product and the hydroboration/oxidation both give a primary alcohol, they are geometric isomers and Y is the trans isomer (Image 2).
For the compound C8H12, the compound in question must be 1,5- cyclooctadiene since two moles of the same aldehyde was obtained after ozonolysis and reaction with two equivalents of hydrogen gives cyclooctane (Image 1).
Answer:
The solution is 10^-2 or 0.01M in HCl.
Explanation:
meaning of pH is "power of hydrogen".
what is the molar concentration of a HCl solution with pH=2?
Let say pH=2
[H+]=10^-2M
HCL is a strong acid that dissociates completely:
[H+]=[HCL]
Therefore solution is 10^-2 or 0.01M in HCL.
Answer:
1. 3.83 L
2. 0.368 mole
Explanation:
1. Determination of the volume
Pressure (P) = 3.21 atm
Temperature (T) = 202 K
Number of mole (n) = 0.741 mole
Gas constant (R) = 0.0821 L.atm/molK
Volume (V) =?
The volume can be obtained by using the ideal gas equation as illustrated below:
PV = nRT
3.21 × V = 0.741 × 0.0821 × 202
3.21 × V = 12.3497283
Divide both side by 3.21
V = 12.2888922 / 3.21
V = 3.83 L
Thus, the volume of the gas is 3.83 L
2. Determination of the number of mole.
Pressure (P) = 2.50 atm
Temperature (T) = 215 K
Volume (V) = 2.60 L
Gas constant (R) = 0.0821 L.atm/molK
Number of mole (n) =?
The number of mole can be obtained by using the ideal gas equation as illustrated below:
PV = nRT
2.50 × 2.60 = n × 0.0821 × 215
6.5 = n × 17.6515
Divide both side by 17.6515
n = 6.5 / 17.6515
n = 0.368 mole
Thus, the number of mole of the gas is 0.368 mole.
