1. At an environmental testing lab, a lab technician calculated the known concentration of the calibrating solution three times too high. How will this affect the results of the samples run using this calibration solution
Answer:
The deviation in the results will be too large when compared with the actual result
Explanation:
The effect this will have on the results of the samples run using this Calibration solution is that the deviation in the results will be too large when compared with the actual result that was supposed to be obtained. and this will also lead to wrong analysis by the technician .
This will cause a result that is very different from the actual result, which will lead to errors in the analysis.
We can arrive at this answer because:
A laboratory test must be done accurately and all calibrations must follow the test protocol.Changing the calibration will cause inaccurate and incorrect results, which differ from the actual result.This will promote an analysis that is unreal, false, and far from true, which will leave the entire test inaccurate.As we can see from the question above, the lab technician used a much higher calibration than what was recommended in the lab. This will lead to inaccurate and incorrect results.

Explanation:
The iodide (I2) content of a commercial mineral water was measured by two methods that produced wildly different results.6 Method A found 0.23 milligrams of I2 per liter (mg/L) and method B found 0.009 mg/L. When Mn21 was added to the water, the I2 content found by method A increased each time that more Mn21 was added, but results from method B were unchanged. Which of the Terms to Understand describes what is occurring in these measure- ments? Which result is more reliable?
Answer:
Results from method B is more reliable than method A.
Explanation:
The two method that are used for the analysis produced different results. The first method that is method A gives higher value of the iodine content than the method B.
When [tex]$Mn^{2+}$[/tex] was added to water, method A showed an increased in the iodine content and it increases with the increase in the amount of [tex]$Mn^{2+}$[/tex] .
Where as in the method B, there is no change in the results. Therefore the measurements provided by the method A shows an inference of [tex]$Mn^{2+}$[/tex] ion.
The measurement of the iodine content is affected by the presence of the ion [tex]$Mn^{2+}$[/tex] in water.
Since in method B there is no change in measurement, it is independent of the presence [tex]$Mn^{2+}$[/tex] ion in water.
As higher iodine content is given by method A, so [tex]$Mn^{2+}$[/tex] ion must be present in original water that must be interfering the measurement. Hence, method B is more reliable.
Method B is more reliable as its value is not altered by external factors such as contamination.
What is water analysis?Water analysis is done to test the quality of water.
The method employed in water analysis is titrimetric analysis.
In the test iodide (I⁻) content of a commercial mineral water using the two methods, the results of the test showed different values for the iodide content.
However, since addition of Mn²⁺ to the mineral water increases the iodide content value from Method A while that of Method B remains unchanged, Method B is more reliable as its value is not altered by external factors such as contamination.

A collapse can be symmetrical or lopsided. Therefore, the correct option is option D among all the given options.
What is black hole?The event horizon of a black hole is an area of spacetime wherein gravity is so intense that nothing, not even light or even other electromagnetic waves, have the energy to cross it. According to general relativity theory, a compact enough mass can bend spacetime into a black hole.
The event horizon is the line beyond which there is no escape. Despite having a significant impact on the outcome and conditions of an object traversing it, general relativity states that it lacks any locally observable characteristics. A black hole behaves in many ways like a perfect black body since it does not reflect light. A collapse can be symmetrical or lopsided. This helps answer the question asked previously.
Therefore, the correct option is option D.

Your question is incomplete but most probably your full question was,
If the star was spinning before the collapse, then the black hole will spin, too. If the collapse is perfectly symmetric, a smooth black hole forms. On the other hand, even a slightly lopsided collapse leads to a lumpy black hole, with erratic gravitational effects. The gravity might be strong in some places and weak in others, and pull in different directions. However, a lumpy hole won't stay lumpy for long, because its own gravity will work to smooth it out. —A Black Hole Is NOT a Hole, Carolyn Cinami DeCristofano What information in the passage helps answer the question asked previously?

When ice melts, liquid water performs the act of erosion by carrying away the tiny rock fragments lost in the split. This specific process (the freeze-thaw cycle) is called frost weathering or cryofracturing. Temperature changes can also contribute to mechanical weathering in a process called thermal stress.
Predict the product of the following Wittig reaction: You may want to draw out the reaction of a separate piece of paper before submitting your response. 2-butanone reacts with (C2H5O)2P=O--CHC.Hs with added heat in a potassium salt solution
a) Potassium diethyl phosphate
b) (z)-stilbene
c) 2-methylbut-1-enyl-benzene
d) 2-methylbutene diethyl phosphate
Answer:
c) 2-methylbut-1-enyl-benzene
Explanation:
From the information given:
Wittig reaction is essential for the creation of carbon-carbon bonds which results in the production of alkenes. The presence of the ketone compound ( 2-butanone) is because of its high electrophilic character of the carbonyl carbon. The reaction between 2-butanone with triethylamine in the presence of potassium salt is to catalyze the reaction. This reaction proceeds to yield the product 2-methylbut-1-enyl-benzene.
when comparing ethanol and acetic acid, which one has the most polar bond? and what is that bond?
Answer:
Ethanol is another alcohol, and since there are less carbons in its chain, it will be more polar. So Ethanol is the most polar bond, it has two different types of bonding between its constituent atoms. The bonds between the hydrogen and carbon atoms are nonpolar covalent bonds. The hydrogen-oxygen and carbon-oxygen bonds are polar covalent bonds.
