It's been awhile since I did one of these, but I think it's:
Na2SiO3 + 8HF produces H2SiF6 + 2NaF + 3H2O

What is the name of formula H2SiF6?
Flourosilicic acid
Does hydrogen fluoride burn any container it's put in except glass?
It even is corrosive to glass!!Hydrofluoric acid attacks glass by reaction with silicon dioxide to form gaseous or water-soluble silicon fluorides. This dissolution process proceeds as follows:SiO2 + 4 HF → SiF4(g) + 2 H2OSiO2 + 6 HF → H2SiF6 + 2 H2O
What is the chemical formula for fluoridated water?
Fluoride water is not a generally used term. We speak of fluoridated water when fluorine compounds are added to water supplies to protect against tooth decay. In the US this is usually achieved by adding sodium hexafluoro silicate, Na2SiF6or hexafluorosilicic acid, H2SiF6 to water, H2O. This makes a mixture, not a compound, so there is no new formula.
What is Prozac made of?
Prozac has as its primary active ingredient FluoxetineChemical FormulaC17H18F3NOChemical NameN-methyl-3-phenyl-3-[4-(trifluoromethyl)phenoxy]-propan-1-amineContrary to a previous answer, this compound differs from Fluoride-containing compounds used in topical and systemic fluoride therapy for preventing tooth decay and for water fluoridation, and in many products associated with oral hygiene. Originally, sodium fluoride was used to fluoridate water; hexafluorosilicic acid (H2SiF6) and its salt sodium hexafluorosilicate (Na2SiF6) are more commonly used additives, especially in the United States.
What element can be added to water to prevent tooth decay?
Fluoride-containing compounds are used in topical and systemic fluoride therapy for preventing tooth decay. They are used for water fluoridation and in many products associated with oral hygiene. Originally, sodium fluoride was used to fluoridate water; hexafluorosilicic acid (H2SiF6) and its salt sodium hexafluorosilicate (Na2SiF6) are more commonly used additives, especially in the United States. The fluoridation of water is known to prevent tooth decay and is considered by the U.S. Centers for Disease Control and Prevention as "one of 10 great public health achievements of the 20th century". In some countries where large, centralized water systems are uncommon, fluoride is delivered to the populace by fluoridating table salt. Soluble fluoride salts, of which sodium fluoride is the most common, are mildly toxic but have resulted in both accidental and suicidal deaths from acute poisoning. While the minimum fatal dose in humans is not known, the lethal dose for most adult humans is estimated at 5 to 10 g (which is equivalent to 32 to 64 mg/kg elemental fluoride/kg body weight). However, a case of a fatal poisoning of an adult with 4 grams of sodium fluoride is documented,while a dose of 120 g sodium fluoride has been survived. In some countries, as part of an antenatal course, expectant women are provided fluoride tablets to help strengthen the eventual tooth structure of babies.
Chemical used for glass etching?
Hi, Flourine is the element. When combined with hydrogen to form hydrogen fluoride, and the dissolved in water to form hydrofluoric acid. As hydofluoric acid, it will etch glass. Hydofluoric acid has a single hydrogen atom and one fluorine atom, physicaly its like hydrochloric acid, a clear liquid. The formula for hydroflouric acid is HF. Search Wiki for "hydrofluoric acid" to get more detail. Hope this helps, Mike
What element is added to toothpaste to prevent tooth decay?
Fluorine and fluoride are made up of each other and are found mostly in toothpastes to strengthen teeth. Dentists often spread a fluorine paste over a patient's teeth to harden the enamel of their teeth.
What is the method used to extract lead metal?
Galena is the principal mineral found in lead and contains roughly 87% of leadâ??s weight. In addition, lead is also found in ore that contains either silver or copper zinc. It is commonly known to be extracted from these minerals.
