The silicate anion in the mineral kinoite is a chain of three $$SiO_4$$ tetrahedral that share corners with adjacent tetrahedral. The mineral also contains $$Ca^{2+}$$ ions, $$Cu^{2+}$$ ions, and water molecules in a $$1:1:1$$ ratio. The mineral is :

Borax is converted into crystalline boron by the following steps:

$${Borax  \overset{X}{\rightarrow} H_3BO_3\overset{\Delta }{\rightarrow} B_2O_3\xrightarrow[\Delta ]{Y} B}$$
Then $$X$$ and $$Y$$ are respectively:

One type of silicon adhesive uses a polymer that has two $$OH$$ groups left on the ends of the chain:
$$HO-Si(CH_3)_2[O-Si(CH_3)_2]_n-O-Si(CH_3)_2-OH$$
It has been found that this kind of polymer reacts easily with an organic-silicon molecule that contains acetate $$(CH_3COO)$$ group. Which of these three molecules $$CH_3COOSi(CH_3)_3$$,  $$(CH_3COO)_2Si(CH_3)_2$$, $$(CH_3COO)_3SiCH_3$$ would you choose to add to the hydroxy polymer in order to make a strong adhesive?
