Consider the unbalanced chemical equation below: CaSiO3(s) + HF(g) - CaF2(aq) + SiF4(q) + H20(1)
Suppose a 31.5 g sample of CaSiO3 reacted with 31.5 L of HF at 27.0 °C and 1.00 atm. Assuming the reaction goes to completion, calculate the mass (in grams)
of the SiF4 and H2O produced in the reaction.
