What is the difference between zinc conversion coating and zinc passivation?
Doas anybody knows?
What does zinc and water produce?
When zinc reacts with water, it forms zinc hydroxide and hydrogen gas. The reaction rate depends on the presence of acids or other ions in the water.
Is zinc molecular?
It would be more correct to say that Zinc is an element
How can zinc be separated from lead?
You could submerge the galvanized iron in HCl, which would then dissolve the zinc, at which point you could weigh the iron again to determine the mass of zinc that was removed.
Would you die if you ate zinc?
No.

Why is granulated zinc used instead of a block?
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.
Suppose you were dissolving a metal such as zinc with hcl. How would the particle size of the zinc affect the rate of its dissolution?
Smaller particle size of zinc would increase the rate of dissolution due to increased surface area available for reaction. More surface area means more zinc atoms are exposed to the acidic solution, leading to faster dissolution compared to larger particles with less surface area.
What type of bond would zinc and zinc have?
They would have a metallic bond.

What metal would you use to make zinc chloride?
as the name suggests, you would need zinc.
What is the name for ZnO?
That would be zinc oxide.
How would you extract zinc from a zinc containing mineral?
to extract zinc from its mineral you can heat it with carbon
A 5.0-gram sample of zinc and a 50-milliliter sample of hydrochloric acid are used in a chemical reaction Which combination of these samples has the fastest reaction rate?
The faster reaction rate will likely occur when the zinc and hydrochloric acid are in a greater contact surface area. In this case, the 5.0-gram sample of zinc will have a higher surface area compared to the 50-milliliter sample of hydrochloric acid. Thus, the combination with the fastest reaction rate is the 5.0-gram sample of zinc.

What is white trivalent passivate my UK customer specifies zinc plate white trivalent passivate?
A 'trivalent passivate' is a 'conversion coating' applied to a zinc surface. It is called a 'conversion coating' because it converts the zinc to a coating comprising zinc and trivalent chromium salts. These products and processes have been developed in response to End-of-Life-Vehicle requirements in Europe and Restrictions on Hazardous Substances (RoHS). Their performance is inferior to classical hexavalent chromates and they are more expensive to apply.
Would zinc and tin nitrate react?
Yes, zinc and tin nitrate would react with one another. When zinc is added to tin nitrate solution, a displacement reaction would occur, with the zinc displacing the tin from the nitrate compound to form zinc nitrate and tin metal.
