already did part a, can someone please help me do the rest? thank you :)

1) Silicon dioxide reacts with hydrochloric acid to produce silicon tetrafluoride and water vapour. SIO2() + HFC) SIF (9) + H2O() a) Write a balanced chemical equation for the above reaction (1 mark). SIO2(s) + 4 HF(aq) - SiF4(9) + 2 H20(9) b) If 12.2g of SIO2 is reacted with 19.6g of HF, what is the theoretical yleld of water (5 marks)? c) Identify the limiting and excess reagents (2 marks)? I d) If the actual yield is 6.50g, what is the percentage yield of the reaction (1 mark)? e) What is the mass of the limiting and excess reactants remaining once the reaction is complete (4 marks)
