No, it won't lift off the table, although you could tie up the balloons once they are filled and they tie a match to the end of a stick. Then light and put out the match and from a safe distance, touch the unlit match to the balloon then you get a small ball of fire.
First of all, place bits of the magnesium into a test tube. Then pour the acid into the tube, in the meantime locking the tube with a balloon. Tighten it up and theres your stored hydrogen :)
Hydrogen atoms are less dense than the air, therefore hydrogen balloon rises in air.
A hydrogen balloon will deflate the fastest because molecules of hydrogen are the smallest and thus will more easily slip through the latex of the balloon. The carbon dioxide-filled balloon will deflate the slowest because these molecules are the biggest, and thus will have more trouble escaping the tiny pores in the balloon.
bcoz hydrogen gas is less denser than air and is exerts buoyant force on balloon
The hydrogen in a sealed rubber party balloon is compressed slightly by the balloon rubber. So its density decreases a little, its pressure increases, and its temperature increases. But the temperature soon returns to the ambient temperature as heat is lost through the balloon wall. Also, the hydrogen will not stay in the balloon for long because it will leak out through pores in the rubber.
Mix Hydrochloric acid with strips of magnesium and catch the resulting gas using a balloon over a test tube

in a balloon and in a hydrogen car
A hot air balloon doesn't contain helium or hydrogen.
A balloon with CO2 instead of helium or hydrogen
There is the weather balloon, and the zeppelin. Both use Helium, and no longer Hydrogen due to hydrogen's tendency to quickly catch fire.
hydrogen
Hydrogen is lighter than helium. So hydrogen balloon will float better than helium.

beecause hydrogen is less dense and light then air , easy to fly..the hydrogen in the balloon is lighter than the air outside of it.density of hydrogen is lower than air
If the balloon were lofted by hydrogen, it would not be a "hot air" balloon, as no heat would be needed. Indeed, to get even a spark near the hydrogen would be for the balloon to go up in a huge fireball. Hydrogen was abandoned as a lift gas for lighter -than-air craft in the 1930's, exactly for that reason.
