-48x^3 + 32x^2 -8x
A student fails to fill the cuvette 2/3 full with the reaction mixture ( CV+ and OH-). What effect does this error have on the measured absorbance values? Thank you :)
In a reaction, if the concentration decreases faster, that means the reaction has a larger rate constant, and a faster reaction, and a shorter half-life. Is that a correct statement? If not, please correct me, thanks for your help :)
Physics Changing Acceleration
Derive position, velocity, and acceleration kinematics equations for an object undergoing a changing acceleration? I understand that somehow we need to get (∆a/∆t) as the change in acceleration into the kinematic equations but I really don't know where to start.

A block is resting on top of a rough incline with coefficients of kinetic and static friction of 0.25 and 0.45 respectively. The angle of the incline is gradually increased until the block just begins to slip. How long will it take the block to slide to the bottom of the incli...
We have to mixed 2 hydrated compounds each in a separate beaker filled with water, and then dump one of the solutions into the other and mix that, then filter the 1 solution out, so that the precipitate is caught in a filter paper, and the water is caught in an erlynmeyer flas...
So I did an experiment at school in which we had to form 2.00 grams of precipitate by mixing 2 hydrated compounds. So for the products, obviously one of it is water, and the other 2 products are compounds, one of which, is insoluble. So when I measured the amount of precipitat...
Oh! That makes much more sense, so the chemical factor is used to keep the atom of interest equal, which in this case was the Fe, and when we look at the atom of interest we don't need to worry about the rest of the formula being balanced, meaning in the example, as long a...
So the bottom line is, that the chemical factor is used to make the amount of atoms equal?
So when you wrote the balanced equation, how did you know that you had to add O2 in the equation? Thanks, sorry for the trouble
