What does mean molten zinc?
hot zinc
Is zinc hot or cold?
Zinc can be virtually any temperature as can nearly all substances. No substance in inherently hot or cold.
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.
What two material become hot easily?
Copper Zinc
HOW CAN CRYSTALS BE OBTAINED FROM HOT CONCENTRATED SOLUTION OF SALT?
by cooling and then filtering

How do you convert benzaldehyde into phenyl acetic acid?
1.First add CH3-MgCl(Grinard). 2.Then and dilute acid or water. 3.Then add Concentrated H2SO4 and heat above 170 degrees celcius. 4.Then add HBr or HCl or HI. 5.Then add dilute KOH or NaOH. 6.Then add Hot concentrated KMNO4.
When nacl and hcl combine is this a neutralization reaction?
HCl or hydrochloric acid will react with NaOH (sodium hydroxide) in a netralisation reaction. HCl is a strong acid and NaOH is a strong base or alkalai. The resultant solution will be warm/hot due to the exothermic reaction taking place. This is an aggressive reaction if the materials are concentrated. HCl + NaOH --> H2O + NaCl
What is the effect on zinc granules when added to dilute sulphuric acid?
the test tube which holds the zinc becomes hot , the zinc turns into zinc chloride and hydrogen gas is produced. It is a chemical change.

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
If lye NaOH is placed in water the solution gets very hot. what kind of reaction is this?
It is a chemical reaction
