For the given reactions
`SiO_(2) +4HF rarr SiF_(4) +2H_(2)O, DeltaH =- 10.17 kcal`
`SiO_(2) +4HCI rarr SiCI_(4) +2H_(2)O, DeltaH = 36.7 kcal`
It may be concluded that
A. HF and HCl both will react with silica
B. Only Hf will react with silica
C. Only HCl will react with silica
D. Neither HF nor HCl will react with silica
