You can also solve for the constants using a system of linear equations.
\frac{3x^2 +12x +11} {(x+1)(x+2)(x+3)}=\frac{A}{(x+1)}+\frac{B}{(x+2)} +\frac{C}{(x+3)}
Multiply both sides by the common denominator
3x^2 +12x +11=A(x+2)(x+3)+B(x+1)(x+3)+C(x+1)(x+2)
3x^2 +12x...
Ignore P1V1=P2V2 because nothing is changing.
You found the volume of SO2. In this instance, it is safe to assume that this is an ideal gas. Do you know how to convert a volume of an ideal gas into moles?
You forgot to multiply the added 1 and 9 on the right side by 16. Either multiply everything out on the left side and see what needs to be added to equalize the right side or try going back and dividing everything by 16 before completing the square.
The overall idea deals with electronegativity. Basically, some elements have more "electron attraction power" than others. Electronegativity varies from element to element.
It is incorrect to say that compounds consist of ions. An ion is an individual atom or molecule that has a distinct...
You are correct on everything. A pipette is an extremely accurate piece of glassware that always delivers the same amount of fluid to a flask if used properly (or breaker or some other container). The burette delivers a titrant, allowing you to observe how much titrant is needed to reach your...
I guess technically deceleration does not exist as an entity in itself, but it is just a descriptive word. As was stated, deceleration is just acceleration in the opposite direction. What happens when you finally reach a velocity of 0 and start accelerating in the opposite direction of where...
Let's use an exaggerated example. Presuming that a stronger negative e- field is forced on the interior wall like you said. If you drew a gaussian sphere around the hollow sphere, which way would this particular electric field point? If you think about it, if a negative charge were to be...
You should not use this because this neglects the affect of the rolling of the cylinder. Also, check your acceleration with a force-diagram (unless you meant SsinӨ).
However, as you have already stated
, the conservation of energy includes the rolling. Make sure to check your calculations...
Sorry. I stand corrected.
Jean-Louis may come and correct me on this (in which case I am sorry for explaining how to do it), but I do not believe it is his desire or care to learn how to derive formulas; he states that he has an aquarium that he wants to apply this to, so why make him try to...
Thats correct. Your flaw comes when you try to use 1.6 as the change in time as time is a variable.
Ok, I lied when I said that there you use only one form of an equation, there are two.
The one you defined is the one you should use first. If you set up two equations, you'll end up...
Hi,
Do you know of any of the kinematic equations that may be relevant here (maybe one that deals with displacement and there are only a few)?
And no, you cannot use a single equation ( you are going to have to use two equations, though they are both the same type of equation kinematic...
This is incorrect as if you change the water 180 times and remove 0.83 gallons each time you get (0.83 gallons/day)*(180 days) = 149.4 gallons
--
Let your volume be X and months be Y (as you requested), then the amount of water you would change per day would be 0.95X/(Y*30) = dv/dt = 0.005277V...
