Question

1.na2co3+sio2= 2.caco3+sio2= 3.na2sio3+casio3+sio2=

Answer 1

1. Reaction: Na2CO3 + SiO2

The reaction between sodium carbonate (Na2CO3) and silicon dioxide (SiO2) can be represented as follows: Na2CO3 + SiO2 → Na2SiO3 + CO2

In this reaction, sodium carbonate reacts with silicon dioxide to form sodium silicate (Na2SiO3) and carbon dioxide (CO2) [[8]](https://dokumen.pub/11-2nbsped-9785360080015.html).

2. Reaction: CaCO3 + SiO2

The reaction between calcium carbonate (CaCO3) and silicon dioxide (SiO2) can be represented as follows: CaCO3 + SiO2 → CaSiO3 + CO2

In this reaction, calcium carbonate reacts with silicon dioxide to form calcium silicate (CaSiO3) and carbon dioxide (CO2).

3. Reaction: Na2SiO3 + CaSiO3 + SiO2

The reaction between sodium silicate (Na2SiO3), calcium silicate (CaSiO3), and silicon dioxide (SiO2) can be represented as follows: Na2SiO3 + CaSiO3 + SiO2 → Na2Ca(SiO3)2 + SiO2

In this reaction, sodium silicate, calcium silicate, and silicon dioxide react to form sodium calcium silicate (Na2Ca(SiO3)2) and silicon dioxide.
