Open Question: why do the bond lengths of carbonyl groups increase as their stretching frequency decrease?
sl5577 Member since:April 08, 2007Total points:101 (Level 1)For example,1,3-dichloroacetone has a bond length of 1.227 Ångstrom with its carbonyl group stretching frequency of 1753cm-1 while cyclopentanone has a bond length of 1.230 Ångstrom with a carbonyl stretching frequency of 1747 cm-1Answer QuestionBe the first to answer this question.

Open Question: why do we have to balance chemical equations?
danie Member since:April 25, 2011Total points:95 (Level 1)why do we have to balance chemical equations? does it have anything to do with the law of conservation of mass?Answer Question by game_b0y... Member since:March 25, 2008Total points:124 (Level 1)Yes. It has almost everything to do with the law of conservation of mass. Mass can be neither created nor destroyed, therefore you can't have more mass on one side than another. So, in order to make this work, you must balance out the equation so that there are exactly the same number of each element on each side of the reaction.
Open Question: If the pitch of a sound increases, what happens to its frequency, wavelength, velocity, and amplitude?
If the pitch of a sound increases, what is the difference in each of the following?
a. frequency
b. wavelength
c. velocity
d. amplitude
So far I think I've found that the frequency increases, wavelength decreases, and velocity and amplitude remain the same. Is that accurate?
Thanks!!!!

Thanks in advance.
Open Question: Find the inverse of f(x) = ln(x - 3)?
x = ln (y - 3)
e^x = y - 3
e^x + 3 = y = f^-1 (x)
The domain of f^-1 (x) is {real numbers}, which is the range of f(x).

Open Question: It really bothers me how people think their is more stars than grains of sand in every beach?
R*B CHIVAS Member since:October 27, 2010Total points:33 (Level 1)it isn't true peopleI have a water bottle filled with sand from Hawaii
and it is a whole bunch
there is like infinity in tha bottleAnswer Question
by Matthew O Member since:July 26, 2006Total points:1,292 (Level 3)It really bothers me when people can't write.
by Amy Bluzzy Member since:February 18, 2011Total points:102 (Level 1) by Nathan Member since:February 10, 2010Total points:4,171 (Level 4)That's because there ARE more stars than grains of sand on this planet. Your example of the water bottle is completely ignorant. There is a limited capacity that the bottle can hold, meaning, that there are so many grains of sand inside the bottle that can actually be counted (it would take a long time, but could still be counted grain by grain)
Open Question: Can someone check my answer for a statistics problem?
n = 30
If the original distribution of x values is known to be normal, do we need to make any restriction about sample size in order to claim that the distribution of sample means taken from random samples of a given size is normal?
Yes
Thanks

Open Question: What is wrong with this answer?
Every sample of size n from the population has a proportionally weighted chance of being selected.
Each subset of the population has an equal chance of being included in the sample. X
Every member of the population has an equal chance of being included in the sample. X
The simplest method of selection is used to create a representative sample.
Every sample of size n from the population has an equal chance of being selected. X
Open Question: How many atoms of each element are there in one molecul of the following substances?
For example, CO2 is a molecule, and there is one carbon atom and two oxygen atoms.
So in N2, there are two nitrogen atoms,
In H2O , there are two hydrogen and one oxygen.
In C2H60 (which won't ever actually exist) there would be two carbon, and 60 hydrogen.
In C12H22O11, there would be 12 carbon, 22 hydrogen, and 11 oxygen.
So if you just take the subscripts for any given covalent compound, you can know how many of that atom is present in a molecule, since the molecule is represented by the formula.
