How was papper 9701 / 12 chem MCQ ?

[ahmed butt]

Was that one D? Zn, (either one of NaF or KCl), and SiCl4?
C was Zn, (either one of NaF or KCl), and HCl..

Was SiCl4 hydrolysed to form HCl (and SiO2), where HCl conducts electricity in aqueous? So answer is D, right? I have a bit of doubt in this one, but my gut says D..

its not liquid HCl its gas

i did C as the thing needs to be melting at -100 something so it is a gas and hcl is a gas at room temp. Answer was C i am pretty sure.
