As part of our chemistry coursework, everyone in my class had to create a glue strong enough to stick a wooden chair to the wall.
The teacher said my effort was the best.

I nailed it.

You'd think that atoms bonding with other atoms would mean they're being friendly, but really they steal each other's electrons.
How ionic.

My friend asked me if I know any good jokes about sodium.
I said, "Na."

What does "autoprotolysis" mean? :)

I had an interesting time trying to figure this one out: Basically if you have less reactants than products, more reactants are going to tend to form to establish a state of equilibrium. If you have less products than reactants, more products are going to tend to form to establish a state of equilib...

On page 134 it says "Also use K to calculate the concentration of a species at equilibrium."

What is "a species"?

Does anyone have any suggestions on how to make studying the molecular shapes fun and engaging? :D

smuhammad1Section1E

So from my understanding, there is a way to calculate the electron affinity...if that is the case, how would I go about doing such calculations.

"You're a 10? Maybe on the PH scale because you're basic."

I thought this was hilarious xD

What exactly is subshell notation and how would I approach this question?

2.27) Write the subshell notation (3d, for instance) and the
number of orbitals having the following quantum numbers:
(a) n 5, l 2; (b) n 1, l 0; (c) n 6, l 3; (d) n 2,
l 1.

Thanks :)

13. A solution is prepared by dissolving 55.1 g of KCl in approximately 75 mL of water and then adding water to a final volume of 125 mL. What is the molarity of KCl(aq) in this solution?

using MiVi=MfVf what would I be solving for?

Steps: 1. Since the mass percentage compositions are given, assume the sample amount is out of 100 g so you can just write the percentage amounts as the gram amount of each element. 78.11 g of C 7.02 g of H 14.86 g of O 2. Convert the gram amount of each element to moles. 6.503 mol of C 6.96 mol of ...

Steps: 1. Find mass of each element in xylitol 2. Calculate the moles of each of the elements in xylitol 3. Write the moles of the elements in xylitol as the subscripts for each element to get the molecular formula. Note: in this case, the empirical formula is equal to the molecular formula because ...

Steps:
1. Balance the Equation (part A)
2. Convert 5.43 g of Al to mol of Al, then take the ratio of the Al to AlCl3molecules from the balanced equation (2Al + 6HCl-------> 2AlCl3 + 3H2), then convert the moles of AlCl3 to grams

Final Answer: 26.982 g of AlCl3
