Answer:
carbonate ion < carbon dioxide < carbon monoxide
Explanation:
Bond strength depends on the bond order of a bond. The higher the bond order, the greater the bond strength since shorter bonds are stronger than longer bonds.
The carbonate ion has a bond order of 1.33, carbon dioxide has a bond order of 2 while carbon monoxide has a bond order of 3.
Since the compound with the highest C-O bond order has the strongest C-O bond, then carbon monoxide possesses the strongest C-O bond.
Well, think of it this way. If you put a big paper circle on the ground, and then you put smaller circles on top of the big circle, which one would have been there longer? The big circle, of course. So the same logic applies here: if the smaller craters had been older than the big crater, then when the big crater was formed, the smaller ones would've been buried. Therefore, crater 2 is older than the smaller craters inside it.
Hope that helped! =)
Answer:
The calcium concentration must be greater outside the cell than inside the cell.
Explanation:
My previous answer was deleted from the explanation I provided from another website.
P: Good conductor of heat and electricity - R: the delocalized electrons are
free to move around the structure
P: High melting and boiling points - R: the bonds in metals are very strong
P: Ductile (can be stretched and squashed) - R: because the electrons are free to move, the atoms can slide over each other.
P: Malleable (can be hammered into shape) - R: the bonds in metal don't break easily
