In which process zinc chloride is by products by use zinc dust?
Zinc chloride is produced by the reaction of hydrochloric acid with zinc metal. Zinc dust is often used as a reducing agent in this reaction to produce zinc chloride. The byproduct of this reaction is hydrogen gas.
How do you activate zinc dust?
Procedure to activate zinc dust: 1. Measure out 0.060 g zinc dust, put in a medium sized test tube 2. add 2 drops of water (distilled) 3. add 6 drops of 3M HCl, you should see bubbles if you do not add more HCl 4. let this react for 30 seconds 5. add water until the zinc settles to the bottom of the test tube 6. decant off the water The zinc is ready to be used. Use it RIGHT AWAY!
How would you separate a mixture of iron dust and zinc dust?
To separate a mixture of iron dust and zinc dust, one method is magnetic separation. Iron is attracted to a magnet, so passing a magnet over the mixture will attract the iron particles, leaving the zinc particles behind. Another method is to use a sieve or mesh to physically separate the larger iron particles from the smaller zinc particles based on size differences. Lastly, if the mixture is dissolved in a liquid, zinc dust can be separated from iron dust using a process called filtration, where the liquid is passed through a filter that traps the larger iron particles while allowing the smaller zinc particles to pass through.
What happen when you add few grains of zinc dust to 5 ml of dilute hydrochloric acid solution?
When you add zinc dust to dilute hydrochloric acid, a chemical reaction takes place where the zinc reacts with the hydrochloric acid to produce zinc chloride and hydrogen gas. This reaction is a type of single displacement reaction where the zinc replaces the hydrogen in the hydrochloric acid. The hydrogen gas is released as bubbles and you may observe fizzing or effervescence.
Does a fever reduce iron and zinc required for bacterial proliferation?
Yes, a fever can reduce the levels of iron and zinc in the body as they become sequestered during infection to limit bacterial proliferation. The sequestration of iron and zinc helps limit the availability of these essential nutrients to pathogens, making it harder for them to grow and multiply.
What is the difference between zinc dust and zinc flake?
Zinc dust is finely powdered zinc whereas zinc flake is zinc flakes with larger surface area. Zinc dust is typically used as a pigment in paints and coatings, while zinc flake is used as a protective coating for corrosion resistance.
How do you make at zinc dust by process of the sublimating?
The zinc metal is molten and vaporized then cooled forming dust of zinc. Ing. Jorge Zamalloa Barrera I Worked in zinc refinery in Peru "Minero Peru"
Why is dust explosive?

What happens when you mix sulfur and zinc dust?
Nothing

What is the difference between LEL and UEL?
LEL is the Lower Explosive Limit. The lowest ignitable concentration of a substance in air that will ignite. UEL is the Upper Explosive Limit. The highest percentage of a substance in air that will ignite.
What is the Percentage range of lel and uel for natural gas?
The Lower Explosive Limit (LEL) of natural gas (which is primarily methane). is 5% by volume in air. The Upper Explosive Limit (UEL) is 15% by volume in air
