hey mate !!
a) the gas is h2 we can test it by taking a burning candle near the gas than candle burns with a pop sound .. this proves that it is h2
b) the litmus paper remain same as red there is no change in colour ..
c)it will forms the calcium chloride and water
reaction--->, Ca(OH)2 (s) + 2HCl (aq) = CaCl2 (aq)+ 2H2O (l)
hope it helps !!
