Zinc from zinc oxide is, however, slightly absorbed into the skin. ... At temperatures between about 230–430 °C (446–806 °F), H 2 S is converted to water by the following reaction: H 2 S + ZnO → H 2 O + ZnS. The zinc sulfide (ZnS) is replaced with fresh zinc oxide when the zinc oxide has been consumed.

About Zinc oxide; Zinc oxide weighs 5.607 gram per cubic centimeter or 5 607 kilogram per cubic meter, i.e. its density is equal to 5 607 kg/m³. The density was measured at 20°C (68°F or 293.15K) at standard atmospheric pressure.
Zinc oxide is depleted in the zinc isotope having an atomic mass of 64, which further transforms into a zinc isotope having an atomic mass of 65 under radiation by nuclear neutrons. This conversion of zinc oxide helps prevent corrosion in the reactors.

zeolite supports for the zinc oxide-based sorbents improves conversion, making zinc oxide supported on zeolites a more efficient sorbent. Experimentally, the reactivity of zinc oxide-zeolite particles will be investigated, and kinetic data will be determined for the reaction. The results will then be
The team reasoned the isobutene probably arose from zinc oxide turning ethanol into acetone, then zirconium oxide—influenced by the nearby zinc oxide—turning acetone into isobutene. At the same time, the zinc oxide’s influence prevented the ethanol-to-ethylene conversion by zirconium oxide.
Steel Conversion Coatings (Black Oxide & Phosphate) Black Oxide: Black Oxide is a conversion coating formed by a chemical reaction with the iron in the metal to form an integral protective surface.
An ore contains a mixture of zinc carbonate and lead carbonate. Zinc and lead are produced from this ore by 2 reactions. REACTION 1: The carbonates in the ore are converted into a mixture of zinc oxide and lead oxide
Fresh zinc powder can be used so that the battery acts as though it was a new primary cell. The zinc powder and electrolyte can be combined into the consistency of a slurry, allowing it to be pumped into the battery. Meanwhile, the zinc oxide can be removed and converted back into zinc metal at an alternate processing site.
Zinc Oxide as a Standard Substance in the Solution Calorimetry of Portland Cement Edwin S. Newman (May 10, 1962) Zinc oxide is the standard substance specified for calibrating the heat-of-solution calo rimeters used in determining the heat of hydration of portland cement in several American and foreign cement specifications.
For starters, you know that 0.2 moles of zinc metal are completely converted to zinc oxide in one month. If you were to stick with moles and months, you can say that the rate at which zinc is concerted is "rate" = "0.2 mol month"^(-1) This means that with every passing month, you will convert 0.2 moles of zinc to zinc oxide.
