Why is granulated zinc is preferred to metallic zinc in the preparation of hydrogen using dilute acid?
What else can I help you with?
Why granulated zinc is used in the preparation of hydrogen rather than metallic zinc?
Don't know, because granulated zinc IS metallic itself: solid, elemental Zn.
Why granulated zinc is preferred to metallic zinc in the preparation of hydrogen using dilute acid?
Granulated zinc has a higher surface area compared to metallic zinc, allowing for a faster reaction with the dilute acid. This increased surface area increases the rate of the reaction, resulting in a more efficient production of hydrogen gas. Additionally, granulated zinc prevents the formation of a protective layer of zinc oxide, allowing for continuous reaction with the acid.
Is metallic hydrogen the same as hydrogen?
Metallic hydrogen is a physical state that hydrogen enters under extreme pressure.
What is the texture of lead?
The texture is something like granulated sugar
Why is hydrogen placed with nonmetals?
Hydrogen hasn't metallic properties.
Which jovian planets contain metallic hydrogen?
It is believed that both Jupiter and Saturn contain metallic hydrogen in their interiors due to the extreme pressure and temperature conditions. Uranus and Neptune are not thought to have metallic hydrogen in their interiors.
Does hydrogen have Lustre?
Hydrogen itself does not have lustre as it is a colorless, odorless, and tasteless gas at room temperature. However, in its solid form as metallic hydrogen, it may have a metallic lustre.
Why hydrogen is classified as a non metallic element?
Hydrogen can act similarly to a metal chemically and at very intense pressures it is theorized to be metallic.
Is MgH2 a metallic hydride?
Yes, MgH2 is a metallic hydride because it is a compound formed between a metal (Mg) and hydrogen (H). Metallic hydrides have characteristics such as high hydrogen storage capacity and can release hydrogen gas under certain conditions.
Does earth have liquid metallic hydrogen?
No. Liquid metallic hydrogen only forms when hydrogen is subjected to extreme pressure. Hydrogen is present in trace amounts in Earth's atmosphere in gas form, under low pressure. The core is composed primarily of iron. Liquid metallic hydrogen likely exists in the gas giants Jupiter and Saturn.
Can you make the hydrogen a metal?
Yes. Although hydrogen is a non-metal, there is metallic hydrogen. It is formed when hydrogen is sufficiently compressed and undergoes a phase change; it is an example of degenerate matter. Solid metallic hydrogen consists of a crystal lattice of protons with a spacing which is significantly smaller than a Bohr radius. Indeed, the spacing is more comparable with an electron wavelength. The electrons are unbound and behave like the conduction electrons in a metal. As is the dihydrogen molecule H2, metallic hydrogen is an allotrope. In liquid metallic hydrogen, protons do not have lattice ordering.
What is the most chemically reactive metallic element?
Hydrogen
