Bump, anyone? Still stuck on this

Homework Statement At 25 C a catalyzed solution of formic acid produces 44.6 ml of carbon monoxide gas in 30s. a) Calculate the rate of reaction with respect to CO(g) production. Homework Equations Rate = dC / dT The Attempt at a Solution dC should be expressed in mol/L but I...

is this this the correct structure for 2-methyl, 3-phenylbutane?

Thanks, I understand now

So if there is two double bonds its di-"prefix"-ede ?

Is this 1,3 -butene? or just plain butene?

bump, still stuck on this question, any help appreciated

London forces = hold covalent molecules together Dipole-dipole = Hold polar covalent molecules together hydrogen bonding = formed between electropositive Hydrogen dipole and an electronegative dipole of O, CL, Fl, N

So for example all of those would have Hydrogen bonding because the H is chemically bonded to O in all three examples? All would have weak london forces, I believe, what constitutes dipole-dipole?

Homework Statement All molecular compounds may have London, Dipole-Dipole, and hydrogen bonding intermolecular forces, affecting their physical and chemical properties. Indicate which intermolecular forces contribute to the attraction between molecules in each of the following classes of...

Question stated: Draw an energy level diagram for a Magnesium ion. I suppose the Magnesium ion is Mg 2+ Not much was given, based off this, is it correct?

Homework Statement Create an energy level diagram for a Magnesium Ion Homework Equations n/a The Attempt at a Solution Correct?

Ok first off, I got the velocity at the top 1.56 m/s from part A of the question. TO find the 1.56 m/s I did v = \sqrt{}gr It doesn`t say to assume speed is constant throughout, and I don`t think it is as the keys traveling past the top point will end up going faster because of gravity...

How would I go about finding the velocity at the bottom, I don't think I assume constant velocity. A FBD I drew up, the dot at the bottom is the keys.

Homework Statement Keys with a combined mass of 0.100 kg are attached to a 0.25 m long string and swung in a circle in the vertical plane. What is the tension in the string at the bottom of the circle? Known: Mass = 0.100 kg Radius = 0.25 m Homework Equations Fc = mv^2/r...
