(SiO2)(Al2O3)(H2O)+H2SO4=?
SiO2Al2O3H2O+HNO3=?
I want to know what the products of these reactions would be.
Thanks in advance.

At least only aluminium will probably dissolved.
Al2O3 + 6 H+ => 2 Al3+ + 3 H2O
Silicon dioxide will not be touched.

But where's the acid in the reaction that you are posting?

And why doesn't silicon dioxide react?

The molecule is like in a diamond. Beside hydrogenflouride, no acid can dissolve it.
