Hydrofluoric acid, HF(aq), cannot be stored in glass bottles because compounds called silicates in the glass are attacked by the HF(aq). Sodium silicate (Na2SiO3), for example, reacts as follows: Na2SiO3(s)+8HF(aq)→H2SiF6(aq)+2NaF(aq)+3H2O(l) 3. How many grams of Na2SiO3 can react with 0.730 g of HF?
6)Using the balanced equation: SiO2 + 6HF → H2SiF6 + 2H2O, if 40.0 g SiO2 and...
6)Using the balanced equation: SiO2 + 6HF → H2SiF6 + 2H2O, if 40.0 g SiO2 and 40.0 g HF react, determine: a) how many grams of H2SiF6 are produced, b) the limiting reactant, c) the excess reactant, d) the left over mass of your excess reactant e) the percent yield if 45.8 g H2SiF6 was produced in lab.

3. Hydrofluoric acid, HF, cannot be stored in glass bottles because compounds such as silicates in the glass are attacked by HF as seen in the following example with Naz SiO3 Na2SiO3(s) + 8HF(1) H2SiF6(aq) + 2NaF(aq) + 3H2O(1) a. How many grams of Naz SiO3 dissolve when 225 mL of 0.1256 M H2Sifo is produced? b. How many grams of H2SiFo form when 35.00 mL of 2.78 M HF reacts by this reaction?

Hydrofluoric acid dissolves glass by reacting with silica as shown in this balanced chemical equation. SiO2 + 4 HF → SiF4 + 2 H2O If 15.75 g SiO2 (molar mass = 60.08 g/mol) and 18.25 g HF (molar mass = 20.01 g/mol) are combined, how many grams of SiF4 (molar mass = 104.1 g/mol) could be produced? How many grams of SiO2 AND how many grams of HF will remain when the reaction is complete? If 16.39 g SiF4 were...

Substitution occurs more readily when a halide ion (eg cl from HCI) is present, resulting in the -OH group of the alcohol being replaced by a halogen atom. A strong acid is necessary, since the H* converts the -OH group into - OH2*, which can then be lost as a water molecule: CH3 H2C=C elimination CHą -H,,! CH3 CH3 CH3 CH3 H3C-Ć-OH H3C-Ć-ÖH2 + H2O + H3C-c@ сна CH? CH3 2-methyl-2-propanol C H3C-C-Cl a 3° carbocation substitution CH3 2-chloro-2-methylpropane Carbocations...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
