It reacts with zinc to form zinc sulfate and hydrogen
HCl is more acidic.. so it reacts faster.
Copper metal does not have enough reactivity to react with sulfuric acid.
With the exception of boron which is unreactive , yes and each member of the group behaves differently. Silicon reacts to hot base and is almost unreactive to acid. Germanium and arsenic reacts to hot concentrated sulfuric and nitric but not to sodium hydroxide. Antimony reacts to nitric and sulfuric acid but not to base. Tellurium reacts to acids and bases.
Nitric acid reacts strongly with many metals.
Crystalline/solid boron does not react at all with sulfuric acid. However, finely powered boron will react with sulfuric acid but very slowly.
Metals all tend to lose electrons when they react, but aside from that there is a wide variety in the reacts metals undergo.
There are several metals which do not react with sulfuric acid; once such metal is gold.
Alkali metals reacts violently with water forming a hydroxide and hydrogen; alkali earth metals react with water but no so violent.Other metals doesn't generally react with water at room temperature.
Potassium reacts explosively.
Several gasses can react with metals, but due to the fact that you are asking for a single gas, the most likely answer that you will be looking for is Oxygen. Oxygen reacts with many metals (and non-metals).
Sulfuric acid will react with magnesium and most other metals to produce hydrogen gas.
sulfuric acid in the rain water reacts with calcium carbonate.
