Not normally no, it is sand!
When dissolving CO2 in water it forms a weak acid: H2CO3. SiO2 will not dissolve in water, so it is not acidic (nor base)
The charge of SiO2 is neutral.
The chemical formula for quartz is SiO2, which means it contains one silicon atom and two oxygen atoms per molecule.
Silicon dioxide (SiO2) is a nonpolar molecule.
The balanced equation for the reaction between HF and SiO2 is: 6 HF + SiO2 -> H2SiF6 + 2 H2O. Therefore, each mole of SiO2 reacts with 6 moles of HF. So, 12.5 mol of SiO2 will react with 12.5 mol x 6 = 75 mol of HF.
yes. You have the solid phase (mostly SiO2) and a gas phase in between (air)

147 (g) SiO2 / 60.1 (g/mol) = 2.446 mol SiO2(the molar mass of SiO2 is 60.1 g/mol)

In SiO2, silicon has a charge of +4 while oxygen has a charge of -2. This results in a neutral overall charge for the compound SiO2.
Nitric acid reacts with quartz to form silicon dioxide (SiO2) and nitric oxide gas (NO).
4SiO2 means SiO2 + SiO2 + SiO2 + SiO2 The '4 'tells you that there are four seprate molecules of SiO2 So there will be 4 silicon atoms in 4SiO2 SiO2 also contains 2 oxygen atoms. So overall there will be 4 x 2 = 8 oxygen atoms. SiO2 is silicon dioxide ; sand that you find on a beach. It does form large crystal lattice by a loose combination through the oxygen atoms.
No, it is not.
The formula SiO2 belongs to silicon dioxide. Another name for silicon dioxide is sand!
