If they give you graphs with activation energy, the graph with the higher activation energy will be slower than the other bc it will take longer and more energy to carry out the reaction.

A neutron walks into a shop and says,"I"d like a coke."
The shopkeeper serves up the coke.
"How much will that be?" asks the neutron.
The shopkeeper replies, "For you? No charge."

Why do chemists like nitrates so much?
They're cheaper than day rates.

H2O is water and H2O2 is hydrogen peroxide. What is H2O4?
Drinking.

704887365

Why should you never trust atoms?
Bc they make up everything

Q is calculated under conditions at any given time while K is calculated while the reaction is at equilibrium.

704887365

I’m not sure how to explain it quantitatively but work done reversibly does not lose as much heat energy (due to friction and other unwanted processes)

704887365

Work = 0 in free expansion because there is no external pressure applied, so P=0 and therefore w=0. Since ΔU = 0, that means that q=0 as well, so no heat is transferred into the surroundings.

704887365

You can use ICE tables for finding equilibrium concentrations and initial concentrations but you can also use them to find the pH of an acid or base. For instance, to find the pH, you would do -log(x) where x is the change in concentration (C part of the ICE table).

704887365

Yes it will always be 2 because the most number indicates a specific orbital, and all orbitals have 2 electrons

704887365

SiO2 forms a covalent network, and is not molecular. Silicon dioxide does not form individual molecules, and there are no double bonds. Silicon dioxide forms a tetrahedral network of silicon atoms bonded to 4 oxygen atoms so as a whole (if there were 4 Si-O bonds), then the system as a whole would b...

I heard oxygen and magnesium were going out.
I was like OMg!

704887365

Why did the white bear dissolve in water?
Because it was polar.

704887365

Q: Why does hamburger yield lower energy than steak?
A: Because it's in the ground state.

Did you hear Oxygen went on a date with Potassium? It went OK.

704887365

Don't trust atoms. I've heard they make up everything.

Both series apply to the Hydrogen atom. For the Balmer series (corresponds to visible light), the electrons come to rest at the energy level n=1. Meanwhile, the Lyman series corresponds to UV light and its electrons come to rest at the energy level n=2.

i make horrible chemistry puns, but only periodically

You have to use MV=MV, using (1)(0.02)=(4)(M). This will give you the concentration as 0.05M.
