There are substances harder than diamonds, take borazon for example it is much harder than a diamond and is made up of a compound of alternating boron and nitrogen atoms. diamonds are made in the same structure but is not has hard as borazon, so why do we humans stick to such idealogies? look deeper into this and answer the moral of this question, why when somebody is told something and it is beleived for a long time, are they ignorant to the truth? it has happened throughout history.

In a standard textbook for class 12, it was written the the complex Tris-(oxalato)-cobaltate(III) was a diamagnetic inner orbital complex. However, in J.D.Lee, oxalate is a relatively weak field ligand. How, then, is it possible?

1. Must involve exactly two distinct elements or compounds, of any state (solid, liquid, or gas).

2. Must NOT require a catalyst in any form, chemical, thermal, or otherwise. The reaction must happen at room temperature.

3. Must exist in some abundance. e.g. californium and kryptonite is not a good answer.

I WILL give the best answer to someone that lists credentials, even if its "science buff".

If it turns out to be toothpaste and baking soda, or something equally accessible, feel free to PM me the answer to keep children from blowing their hands off. I'll still make sure you get 10 points =D

Part I of my question

Please respond with Moles
__________ 23.94 grams of titanium (Ti)
__________7.090 grams of chlorine molecules (Cl2)


Part II of my question:

Please respond with large number, not moles.
_______14.67 grams of nickel
_______117.3 grams of potassium

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I am confused by these numbers. I looked on chemfinder.com and could not resolve this question. Usually, you find this kind of information in chemistry databases. I am surprised that I didn't.
