Why do you think that granulated zinc is used instead of a block?
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.
Chemical equation for granulated zinc and diluted sulfuric acid?
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.
What are the products formed when granulated zinc reacts with caustic soda?
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.
What is the metal used for galvanising iron?
It is the element zinc in its molten state that we dip iron or steel into to galvanize it.
What is zink oxide?
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.

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 is granulated zinc is preferred to metallic zinc in the preparation of hydrogen using dilute acid?
Granulated zinc has more surface area exposed to the acid, so the reaction can occur more rapidly.
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.
Why is granulated zinc preferred for lab preparation of hydrogen?
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.
What is the meaning of granulated zinc and wolf's bottle?
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.
Chemical equation for granulated zinc and diluted sulfuric acid?
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.
What gas will evolve if granulated zinc and sulfuric acid will react in a test tube?
H2s
What are the products formed when granulated zinc reacts with caustic soda?
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.
What d-block element is in batteries?
Zinc.
Supply zinc oxide and chloride?
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.
Why are metals such as cobalt used in redox enzymes instead of zinc gallium or calcium?
Because that's the way it is in maynooth!
