Homework Statement
A helium atom has a rest mass of He = 4.002603u. When disassembled into its constituent particles (2 protons, 2 neutrons, 2 electrons), the well-separated individual particles have the following masses: p = 1.007276u, n= 1.008665u, e = 0.000549u.

Well, CuI would have to be a solid. And I'm not convinced a solid was formed in this case. I suppose my main question is if the reaction between Cu and I2 results in a color change to Cu, would the product be a solid? CuI would have to be a solid to be written as such in the net ionic equation...
To test the ability of Br2 and I2 to oxidize copper metal, the reactions take place between Br2water and I2 solution with copper:
Cu (s) + Br2 (aq) -> Cu2+ (aq) + 2Br- (Aq)
Cu(s) + I2 (methanol) -> Cu2+ (methanol) + 2I- (methanol).
Write the net ionic equations describing the results of...

Thanks, Kushan. I appreciate your help. I think there might be an issue with the website. It wouldn't be the first time.
Technician: You might notice that is exactly what I attempted to do... No worries though.
Yes, I noticed this as well. I purposely left that out of my equation as we are attempting to solve for ΔB/Δt. I assume it's the authors of the homework trying to trick us into thinking the value is necessary. Though I cannot see how it could be.
It's the online website for our physics homework. When you enter your answer, you are told whether or not your answer is correct. You are given 5 attempts, during which the points you earn diminish.
Homework Statement
A single conducting loop of wire has an area of 8.0×10−2 m^2 and a resistance of 110 Ω. Perpendicular to the plane of the loop is a magnetic field of strength 0.37 T.
At what rate (in T/s) must this field change if the induced current in the loop is to be 0.33 A...
