Yes.
The helium will seep through ths skin of the balloon, reducing its buoyancy.
No. Copper will not replace hydrogen in sulfuric acid because it is less reactive than hydrogen.
Na
Helium has replace hydrogen in airships
A fossil formed in this way is called a petrified fossil. It occurs when minerals gradually replace the organic material in an organism's remains, creating a stone replica of the organism. This process is known as petrification.
Hydrogen from photosynthesis
No. Copper will not replace hydrogen in sulfuric acid because it is less reactive than hydrogen.
A metal higher in the reactivity series than hydrogen, such as magnesium, zinc, or aluminum, can replace hydrogen from acids through a displacement reaction. The metal will react with the acid to form a salt and hydrogen gas is produced.
No, your passport number remains the same when you replace your passport.
He used to be a smart child is the most obvious answer. He remained a smart child maybe.
Yes, in a single replacement reaction, sodium can replace hydrogen in a compound if sodium is more reactive than hydrogen. This involves sodium reacting with a compound containing hydrogen to form sodium compounds and hydrogen gas.
because metal contain positive ions and hydrogen too
Na
When metal atoms replace hydrogen atoms in an acid, it forms a salt and hydrogen gas. The metal reacts with the acid to form the salt, while hydrogen gas evolves as a byproduct. This is a common reaction in chemistry known as a displacement reaction.
This is because metals have positive ions and so does hydrogen. Hence the nature of their reactivity is same but the value of reactivity is different. Therefore metals replace hydrogen in a reaction while non metals dont...

yes if put into HCl it will replace the H and produce hydrogen gas and magnesium chloride
