NaHC0 3 (s) ~ Na2C03(S) + CO 2 (g) + HP(g) c. KCI0 3 (s) Heat) KCI(s) + 02(g) d. Eu(s) + HF(g)-* EuF 3 (s) + Hig) 97. Silicon is produced for the chemical and electronics industries by the following reactions. Give the balanced equation for each reaction. a. Si0 2 (s) + C(s) a:ll~~::~:/ Si(s) + CO(g) b. Silicon tetrachloride is reacted with very pure magnesium, producing silicon and magnesium chloride. c. Na2SiF6(s) + Na(s)-* Si(s) + NaF(s) 98. Glass is a mixture of several compounds, but a major constituent of most glass is calcium silicate, CaSi0 3 . Glass can be etched by treatment with hydrofluoric acid; HF attacks the calcium sil-icate of the glass, producing gaseous and water-soluble products (which can be removed by washing the glass). For example, the volumetric glassware in chemistry laboratories is often gradu-ated by using this process. ...
