2. Using the same method, answer the same questions for mixing 30 gof hydrogen fluoride and 30 g of glass (which is made of silicondioxide) with focus on determining the percent yield of silicontetrafluoride (and water). Silicon tetrafluoride is found involcanic plumes and has some limited use in microelectronics.
HF(g) + SiO2(s) → SiF4(g) + H2O(l)
a) Write a balanced chemical equation for the equationabove.
b) From your balanced chemical equation, what is the molar ratiobetween the reactants and products?
c) What is the stoichiometric amount of moles of SiF4 that can beformed when 30 grams of HF and 30 grams of SiO2 are reacted?
d) What is the theoretical amount (in grams) of nitric acid thatcan be formed when 30 grams of HF and 30 grams of SiO2 arereacted?
e) What is the percent yield of Silicon tetrafluoride?
f) How much of the excess reagent remains?
