What else can I help you with?
Is zinc hot or cold?
Zinc can be virtually any temperature as can nearly all substances. No substance in inherently hot or cold.
What does mean molten zinc?
Molten zinc refers to zinc metal that has been heated to its melting point, which is approximately 419°C (786°F). When zinc is in its molten state, it can be applied as a protective coating to other metals through processes like hot-dip galvanizing.
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.
HOW CAN CRYSTALS BE OBTAINED FROM HOT CONCENTRATED SOLUTION OF SALT?
by cooling and then filtering
How is steel galvanised?
Steel is put in a pool of hot zinc at about 460˚ Celsius (860˚ Fahrenheit).

If lye NaOH is placed in water the solution gets very hot. what kind of reaction is this?
This is an exothermic reaction, which releases heat energy as the lye (NaOH) dissolves in water. This heat is generated due to the interaction between the ions in the NaOH and the water molecules.
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 will be the chemical equation of sulphur reacting with hot concentrated nitric acid?
The chemical equation for sulfur reacting with hot concentrated nitric acid is: S + 6HNO3 → H2SO4 + 6NO2 + 2H2O
When was Hot Action Cop - album - created?
Hot Action Cop - album - was created on 2003-03-04.
How do you dissolve lead sulphate?
Lead sulfate can be dissolved in hot concentrated nitric acid or in hot concentrated sulfuric acid. It can also be dissolved in a mixture of hydrochloric acid and hydrogen peroxide. It is important to handle lead compounds with care due to their toxicity.
How is steel galvanised?
Steel is put in a pool of hot zinc at about 460˚ Celsius (860˚ Fahrenheit).
What do they coat steel with to prevent rusting?
Hot dipped zinc is one common treatment, but there are others.
