Hi! There actually are negative order reactions. A negative order indicates that the concentration of a species inversely affects the rate of the reaction. There is also the possibility for fractional orders of reactions.

Hi! I think you're talking about what Shailyn mentioned with phase changes. When a certain amount of heat is added to water, inducing a phase change from liquid to gas, the temperature of the substance does not change. This is because the heat is being used to break the bonds in the liquid to conver...

Hi! Logs are used because they allow us to evaluate very small quantities of compounds such as the concentrations of the base or the acid in order to find pH and/or pOH. Hope that helped!

Hi! It would be chloride instead of chlorine because chloride is an ion of chlorine; more specifically an anion. The anion of chlorine is needed here because it possesses a negative charge of -1 in order to offset the positive charge of +1 from the coordination complex. Therefore, chloride needs to ...

Hi! [FeCl3(H20)3]- would be triaquatrichloroferrate(II) instead of roman numeral 3 due to the fact that there is an overall negative charge. Cl3 has a total charge of -3 so Fe should have a positive charge of 2 to create an overall negative charge on the complex. Since the complex is an anion, we do...

To add onto that, the 3 lone pairs of electrons around the central atom are arranged in a way where the electron repulsion, in a sense, cancels each other out. There is a force pushing from one side and a force pushing from the other side in order to produce a linear molecule with a bond angle of 18...

Hi! I believe that the VSEPR model and the VSEPR formula are essentially the same thing but just present information in different ways. The VSEPR model is the lewis structure showing the regions of electron density including bonded and lone regions. From the model one can determine the shape along w...

Hi! To be safe you would probably want to write [Xe] as opposed to the other electron configuration. Typically when writing electron configurations you have to start with the noble gas in the prior period that is the closest to the element in question. This is probably where your answer is stemming ...

A photon walks into a hotel and the clerk says, "can I take your bags sir?" The photon replies, "no thanks I'm traveling light."

Hi! Here's a step by step of how I did the problem. 1. Convert 140.511 keV into eV, so multiply 140.511 by 1000. = 140511 eV or 140.511x10^3 eV 2. Convert eV to J. (I had to look up the conversion because I didn't know it) 1eV = 1.6022x 10^-19 J (140511 eV)x(1.6022x10^-19 J) = 2.2513x10^-14 J 3. Fin...

I agree that PCl3 in this case is the limiting reactant. It would be very hard, if not impossible to find the specific mass of the reactant H20 without it being a given quantity or having more information in the problem. Maybe it is assumed that more H20 reactant could be added to the reaction if ne...
