You will get a positive result for hydrogen because the reaction of zinc and hydrochloric acid produces zinc chloride and hydrogen. The chlorine atoms from the hydrochloric acid attach to the zinc, leaving the hydrogen behind and thus, you have hydrogen.
When Cu is added to hydrochloric acid , no reaction takes place. This is because copper is less reactive than hydrogen and does not displaces hydrogen from solution.
minimizes the repulsion of electron groups
We can compress the hydrogen because hydrogen gas is stored in the cylinders.
Generally this concentration is 36.5 %. However cocentrations up to just over 40% are possible but require special pressure and cool temperature conditions because the vapor pressure of the hydrogen chloride (which is dissolved into water to make hydrochloric acid) is high enough to cause evaporation of the hydrogen chloride out of the solution which then reduces the concentration unless you have the pressure and temperature conditions.

Because the gas carbon dioxide is produced.
They will form Hydrogen and Strontium Chloride. Strontium might give out radiation because it should be one of the reactivity series.
when hydrogen chloride is dissolved in water to form hydrochloric acid, the hydrogen chloride turns to HCL subscript 38 because of the water molecules. i also believe that they change from clear to a misty green colour but it may just be the result of a dirty test tube.
Absolutely no reaction, that's because copper is less active than hydrogen. :) )
