Type of Chemical Reaction: For this reaction we have a combination reaction. Balancing Strategies: In this combination reaction we have zinc plus the oxygen gas and they combine to form zinc oxide.

In the indirect (French) process, metallic zinc is melted in a furnace and vaporized at ca. 910 °C. The immediate reaction of the zinc vapour with oxygen from the air produces ZnO. The particles of zinc oxide are transported via a cooling duct and are collected at a bag filter station.

The chemical zinc nitrate is a zinc salt of nitric acid with the chemical formula Zn (NO3) 2. The molecular weight of the compound is 225.18 g / mol.

How to balance the chemical equation Na + O2 → Na₂O. Sodium is a very reactive metal, it tends to react with oxygen to form sodium oxide, but this is an unstable compound and soon reacts with hydrogen to form sodium hydroxide. Sodium is a metal that reacts vigorously with oxygen and water.

Answer: For a: The reaction is synthesis reaction.Jun 20, 2018

Zinc is a chemical element with symbol Zn and atomic number 30. Classified as a transition metal, Zinc is a solid at room temperature.

• Zinc oxide is the metal zinc that has been oxidized. The chemical formula is ZnO, 1 zinc atom and 1 oxygen atom held together by an ionic bond. Zinc oxide does occur in nature as the mineral zincite, but it is quite rare and commercially unavailable.

• Hazards and Risks. Hazards and risks associated with zinc: zinc metal is a human skin irritant and is a severe fire hazard but otherwise is non-toxic. Most common zinc compounds are not very toxic but a few zinc salts may be carcinogens. Use of some zinc compounds is permitted around food. Pollution from industrial smoke may cause lung disease.

• Zinc oxide. Mechanism of Action of Zinc oxide It works by providing a skin barrier and helps in healing and prevent skin irritation. It acts as a sunscreen which absorbs incident solar radiation in the UVA ranges and reduces its transmission to the skin.
