What does mean molten zinc?
hot zinc
Is yellow when heated and white when cold?
Zinc oxide
Why zinc chloride is weighed when it is cold and not hot?
All chemical are weighed cold, generally at 20 0C, to make possible correct comparisons between different weighings. The density of all materials depends on the temperature. Also, hot materials have negative influences on analytical balances.
Does zinc react with oxygen when heated?
Zinc does react when heated. It sparks, then turns to a liquid. The reaction takes place because the zinc combines with the o2 and creates zinc oxide.
Does zinc displace hydrogen from cold water?
Yes , slowly.
Will there be a reaction between zinc and water?
Zinc reacts with steam to form Zinc oxide(yellow when hot and white when cold) and hydrogen. Zn+H2O=ZnO +H2
What does mean molten zinc?
hot zinc
Is cold rolled harder than hot rolled steel?
They are two different things. Zinc plated means it's coated in zinc. Cold rolled means it's "smashed" into shape without added heat. So you could have something that's cold rolled AND zinc plated!
Why does zinc react with steam and cold water?
Zinc does react with cold water - it just does so very slowly. Steam is water that is very hot and thus as with any chemical reaction, the heat gives the molecules more energy and so they react faster.

Why zinc oxide yellow while hot and white while cold?
this has to do with the frequency of light the zinc sends out and reflects. Just as iron turns red and when very hot white zinc turns yellow. In a old light bulb a wire of wolfram is used to create yellow light. So the light that it sends and reflects is a material property
Is zinc unreactive to water?
Zinc is unreactive to cold water, but will react with steam to give zinc oxide and hydrogen.
What formulation of zinc has been found effective in treating the symptoms of the common cold?
Zinc gluconate
Is earth hot or cold?
earth is hot and cold
Is it mostly hot in Rome or cold?
yes it is hot and cold
What is cold when its hot and hot when its cold?
dogs
What is the process involved in making brass?
Brass is the combination of the metals copper and zinc. Its manufacturing process involves melting, hot rolling, annealing and cold rolling, and finish rolling.
