What else can I help you with?
What is the word equation for heating zinc with air?
Zinc Oxide -----> Yellow Crystals (White) HEAT <----- COOL
Why methyl orange is used as indicator in determination of ZnO?
Methyl orange is used as an indicator in the determination of ZnO because it changes color from red to yellow at a pH range of 3.1-4.4, which is suitable for the titration of ZnO with a strong acid like hydrochloric acid. This color change helps in determining the endpoint of the titration accurately.
Is ZnO soluble in water?
Zinc oxide (ZnO) is not very soluble in water.
What metal reacts with steam to give an oxide that is yellow when and white when cold?
Iron reacts with steam to give iron(III) oxide, which is yellow when hot and white when cold.
What is the reaction for h2so4 plus zno?
The reaction between sulfuric acid (H2SO4) and zinc oxide (ZnO) produces zinc sulfate (ZnSO4) and water (H2O). The balanced chemical equation for this reaction is: H2SO4 + ZnO → ZnSO4 + H2O.

Why Heating zinc oxide is a physical change Why?
It is a physical change. I goes from white, to yellow, back to white.

Is yellow flames are ideal for heating?
NO
Is ZnO soluble in water?
Zinc oxide (ZnO) is not very soluble in water.
What metal reacts with steam to give an oxide that is yellow when and white when cold?
Iron reacts with steam to give iron(III) oxide, which is yellow when hot and white when cold.
What is the name of the compound ZnO?
The compound ZnO is called zinc oxide.
Which solid turns yellow on heating?
Sulfur turns yellow when heated.
How can you make a red ball appear yellow?
paint it yellow
What is the reaction for h2so4 plus zno?
