If there is Block of zinc, only the zinc on the surface gets exposed to the other reactants but if there is granulated zinc because of its more surface area the zinc is more exposed so the granulated zinc is used for the greater reaction rate.
Granulated zinc is used instead of a block as the surface area of granulated zinc is much more than that of a block. Hence it's easier for it to react with oxygen if the area is more. This is why it's used.
The Chemical equation for granulated zinc and diluted sulfuric acid is Zn + H2SO4 GIVES(arrow) ZnSO4 + H2O And impurities like arsine (AsH3), phosphine (PH3), CO2, SO2, H2O(gas.) and H2S because granulated zinc has impurities.
When granulated zinc reacts with caustic soda (sodium hydroxide), the products formed are hydrogen gas and sodium zincate, which is a soluble compound. The chemical equation for this reaction is: Zn + 2NaOH -> Na2ZnO2 + H2.
It is the element zinc in its molten state that we dip iron or steel into to galvanize it.
Zinc oxide is a white powder mineral compound made of zinc and oxygen. It is commonly used in skincare products like sunscreens for its ability to protect the skin from ultraviolet (UV) rays. Zinc oxide is also used in various other applications such as in the production of rubber, plastics, ceramics, and paints.

Don't know, because granulated zinc IS metallic itself: solid, elemental Zn.
Granulated zinc has more surface area exposed to the acid, so the reaction can occur more rapidly.
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.
Granulated zinc is preferred for the lab preparation of hydrogen because it has a high surface area, allowing for better reactivity with acids to produce hydrogen gas more efficiently. The granules provide a larger surface for the reaction to occur, leading to faster and more complete production of hydrogen compared to other forms of zinc. Additionally, granulated zinc is easy to handle and measure, making it convenient for laboratory use.
Granulated zinc refers to zinc metal that has been broken or cut into small pieces, often in granular form. A wolf's bottle is a type of laboratory glassware used for distillation and reflux processes, characterized by a round body and a long neck with a constriction near the end to help prevent splashing.

Zinc.
Zinc oxide (ZnO) is a white powder commonly used in ceramics, rubber, and skincare products for its UV-protection and soothing properties. Zinc chloride (ZnCl2) is a white crystalline solid used in industrial processes like soldering and metal coating, as well as in specialized applications like deodorants and disinfectants due to its antimicrobial properties.
Because that's the way it is in maynooth!
