Chemical bonding question! The partial Lewis structure that follows (Figure 1) is for a hydrocarbon molecule. In the full Lewis structure, each carbon atom satisfies the octet rule, and there are no unshared electron pairs in the molecule. The carbon-carb...

Determine which ions have noble-gas configurations: Cd2+ Ru3+ P3− As3− Ag+ Zr4+ Thanks for any help. (I tried As3- and Zr4+, but that was wrong, so maybe i'm just missing one.

Find the number c that satisfies the conclusion of the Mean Value Theorem on the given interval. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) f(x) = √x [0, 9] c=? I've tried quite a few different answers

What is the mole fraction of O2 in a mixture of 15.1g of O2, 8.16g of N2, and 2.46g of H2? (PLEASE EXPLAIN WHAT YOU DO!) Thanks

Have you done the titration yet, and did you make any observations?

Well since its a 1:2500 ratio, you would multiply 12cms by 2500. You then want to divide by 100, since there are 100 cm in a meter. Finally, divide that number by 1000, since there are 1000 meters in a kilometer

There is no C in the original equation, so I'll assume that you mean C is AB. Then there would be 0.5 moles, since A is the limiting reagent, and the mole ratio of A to AB is 1:1 (or 2:2 for the sake of understanding it). Hope this helps. Like I said, its...
