According to Le Chatelier' principle, if a ytem in dynamic equilibrium contain a large exce of reactant, what can be done to encourage the formation of more product?
Answers
According to Le Chatelier' principle, if a ytem in dynamic equilibrium contain a large excess of reactant, to encourage the formation of more product we can remove product from the system as it is formed.
A system in dynamic equilibrium will respond to a stress (change in conditions) in a way intended to reduce that stress. This is the guiding idea of Le Chatelier.
We want to influence the system's response so that it produces more product. A reduction in product results from adding stress to the system by removing some of the product. The system's response is to move the equilibrium to the right to boost product production in order to reduce the stress.

If the sodium bicarbonate is not properly broken down, water and carbon monoxide will not be produced, which can be eliminated to lessen the product's mass. The product will therefore weigh heavier or have a bigger ultimate mass than predicted because of an incomplete reaction.

How is the triple helix of collagen arranged that every third position has to be glycine?
Answers
The triple helix of collagen is arranged in such a way that every third position has to be glycine due to its unique structure and amino acid composition. The collagen molecule consists of three polypeptide chains, each forming an alpha helix, which then intertwine to create a triple helix structure.
Step 1: Understand the role of glycine in collagen
Glycine is the smallest amino acid, and its presence at every third position allows the three alpha helices to pack closely together, maintaining the stability of the triple helix structure.
Step 2: Recognize the amino acid sequence pattern in collagen
The amino acid sequence in collagen typically follows a pattern of Gly-X-Y, where Gly is glycine, and X and Y can be any other amino acids (often proline and hydroxyproline, respectively).
Step 3: Visualize the arrangement of the triple helix
The three polypeptide chains coil around each other in a right-handed helical structure, with the glycine residues from each chain aligning at the center of the triple helix. This arrangement facilitates tight packing and stability of the collagen molecule.
In conclusion, the triple helix of collagen is arranged so that every third position is glycine because its small size enables the close packing of the three helices, providing stability to the overall structure.

what is the relative atomic mass of the element that consists of the following isotopes in the indicated natural abundances? isotope isotopic mass ( amu ) relative abundance ( % ) 1 57.93 67.76 2 59.93 26.16 3 60.93 1.25 4 61.93 3.66 5 63.93 1.16
Answers
To calculate the relative atomic mass of the element, we multiply the isotopic mass of each isotope by its relative abundance, and then sum up the results.
For isotope 1, the contribution to the relative atomic mass is (57.93 amu * 67.76% = 39.24 amu).
For isotope 2, it is (59.93 amu * 26.16% = 15.68 amu).
For isotope 3, it is (60.93 amu * 1.25% = 0.76 amu).
For isotope 4, it is (61.93 amu * 3.66% = 2.27 amu).
For isotope 5, it is (63.93 amu * 1.16% = 0.74 amu).
Summing up the contributions, we get (39.24 amu + 15.68 amu + 0.76 amu + 2.27 amu + 0.74 amu = 58.69 amu).
Therefore, the relative atomic mass of the element is approximately 58.69 amu.

While structural isomers share the same molecular formula, their atoms are bonded differently. Stereoisomers share the same atomic configurations and chemical formulae. Thus, option A is correct.
What favours one possible structural isomer?The term "structural isomer," also known as a "constitutional isomer," refers to a group of two or more organic compounds that share the same chemical formula but have different structures.
Isomers are compounds that share the same molecular formula but differ in the way their atoms or groupings are arranged or oriented. Only the groups' spatial orientation within the molecule distinguishes them from one another.

The environmental half (ta) for trichloroethene (TCE) at your site is 24 months. The current concentration is 120 kg/L. How many years (to the nearest tenth of a year) will it take the TCE to degrade down to the MCL concentration of 5 ug/L?!
Answers
It will take approximately 72.9 years (to the nearest tenth of a year) for the trichloroethene (TCE) concentration to degrade down to the MCL of 5 μg/L.
To calculate the time it will take for TCE to degrade down to the MCL (Maximum Contaminant Level) concentration of 5 μg/L, we can use the concept of "first-order decay" for the degradation process. The formula for first-order decay is:
C(t) = C0 * e^(-kt)
where:
C(t) = concentration at time t
C0 = initial concentration (120 kg/L)
e = base of the natural logarithm (approximately 2.71828)
k = first-order decay rate constant
t = time
The half-life (t1/2) of TCE is given as 24 months, which means that the concentration will decrease to half its initial value in 24 months. The half-life is related to the first-order decay rate constant (k) as follows:
t1/2 = ln(2) / k
Solving for k:
k = ln(2) / t1/2
k = ln(2) / 24 months
Now, we can calculate the time (t) it will take for the concentration to reach 5 μg/L (MCL):
5 μg/L = 120 kg/L * e^(-kt)
t = ln(5 μg/L / 120 kg/L) / -k
t = ln(5e-6 / 120) / - (ln(2) / 24)
t ≈ 72.9 years

calculate the absorbance of a sample that has a percent transmittance of 75%.
Answers
The absorbance of a sample with a percent transmittance of 75% is approximately 0.1249. Absorbance is calculated using the formula A = -log10(Transmittance (%)/100).
Absorbance is a measure of how much light is absorbed by a sample. It is commonly used in spectroscopy to determine the concentration of a substance in a solution. The formula A = -log10(Transmittance (%)/100) relates the absorbance and percent transmittance of the sample. In this case, the percent transmittance is given as 75%.
By substituting this value into the formula and performing the calculation, we find that the absorbance of the sample is approximately 0.1249. The negative logarithm is used in the formula because absorbance is inversely proportional to transmittance.
A higher absorbance value indicates that more light is absorbed by the sample, while a lower value corresponds to higher transmittance and less absorption.

When we have an acid-base reaction, the acid will be that substance that donates protons, in the form of H+ ions. The base will be the one that accepts the H+ ions. Now, the base that accepts the protons becomes a potential proton donor, thus becoming a conjugate acid. This is the case with H3O+.
H2O accepts H+ ions, so it is a base and when it becomes H3O+ it becomes a potential H+ proton donor, that is, a conjugate acid.
