it is not yellow all the time only some are, it can be due to impurities, calcium sodium magnesium ect.
ZnO appears yellow upon heating due to the formation of zinc oxide nanoparticles. The optical properties of the nanoparticles can cause a shift in the absorption spectrum, leading to the yellow color. This change in color is often attributed to the quantum confinement effect that occurs at the nanoscale level.
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.
Iron reacts with steam to give iron(III) oxide, which is yellow when hot and white when cold.
Zinc oxide (ZnO) is not very soluble in water.
Simply a lighter orange and and a more orange yellow.

ZnO is the chemical formula of the zinc oxide.
Rafa's favorite color is yellow.

Answer Pure ZnO has a band gap of ~3.3eV and is therefore colorless. ZnO Powder may have a white appearance due to scattering and a layer of carbonate on the outside of particles as ZnO Reacts with CO2 in the air.

bec of the presence of ZNO by lester gaviola
yellow
An yellow color, from sodium
If you blend yellow with blue, you get the color green. If you blend yellow with red, you get the color orange.
Simply a lighter orange and and a more orange yellow.
