Hi, can someone help explain why they numbered it like this instead of how I numbered it?

The prefixes 'iso-' and 'neo-' are used for common naming instead of IUPAC naming; 'iso-' being used when there are 4 or less carbons, and 'neo-' when there are five or more. Common naming doesn't follow the rule of numbering the longest carbon chain, but instead counts all of the carbons. Using co...

The problem states:

"Determine the rate constant for second order equation 2A -> B + C given that the concentration of A decreases from 2.5 x 10^-3 M to 1.25 x 10^-3 M in 100.0 seconds."

How would you solve this?

The problem states: "Find the initial concentration of HClO with a pH of 4.60 (Ka = 3.0x 10^-8)." I understand you have to use an ICE table to solve for it but I'm not sure how to find the change in molarity with the info given? And after finding the change in molarity do I just solve for x?

The question states: "The reaction N2(g) + O2(g) = 2NO (g) contributes to air pollution whenever a fuel is burned in air at a high temperature. At 1500 K, Kc = 1.0x10^-5. A sample of air is heated in a closed container to 1500 K. Before any reaction occurs [N2] = 0.80 M and [O2] = 0.20 M. Calcu...

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.

The oxidation number is essentially the charge of the metal. So first you would need to calculate the charges of the other ligands in the complex and those charges plus the charges of the metal should add up to the total charge of the complex. For example, take [Fe(CN)5]2-, The charge of CN is 1-, ...

How do you determine the oxidation number of transition metals?

Hi, this was answered in a previous post: "Answer: s-character is the contribution of sigma type bond in a hybridization: sp3 = 25% s-character, 75% p-character sp2 = 33% s-character, 66% p-character sp = 50% s-character, 50% p-character The more s-character a bond has, the stronger and shorter...

Hi, I've memorized the bond angles for all the VSEPR geometries but I don't seem to understand why the tetrahedral shape has angles of 109.5 degrees. It's hard for me to picture it without a 3D diagram. Could anyone explain? Thank you in advance!

How would we be able to tell which molecules have stronger bonds? Or in other words, what makes a bond strong?
