Why does ag not reaplace zn form znso4 solution?
You should have somewhere a list called the Activity Series. Zinc is a more active metal than silver, meaning that zinc will replace silver in a compound, but silver will not replace zinc.
How could you prove that magnesium is a more reactive metal than zinc or iron?
Magnesium react with water and burn easily in air.
What it the alloy of copper an zinc?
Alloys that contain only copper and zinc are usually called "brass"; there are also some alloys that contain one or more other metals in addition to copper and zinc, and these usually have another name.
What does zinc plus oxygen equals?
Zinc is a metal and Oxygen is a non-metal.
Why powdered zinc act more vigorously than metal zinc?
Powdered zinc has a greater surface area giving it a greater chance to react with a substance.
What is an fact about metal?
Pure metal is weaker than alloyed metal. ! and zinc oxide + Gold = zinc oxide + gold. !
What is more dense a 200g sample zinc metal or 500g?
Which is more dense a 200.g of zinc metal or a 500g sample of zine metal?
Which metal Zn or Cu can be oxidized easily?
Zinc is oxidized more easily than copper.
Why does potassium react with water but zinc does not?
Potassium is an alkali metal with one valence electron more reactive than zinc which has completely filled d orbitals. Hence potassium will react with water and not zinc.
Copper cannot displace zinc from its salt solution?
because in table of re-activity of metals it is below zinc

How does copper and zinc sulphate react together?
zinc is more reactive than copper hence it displaces the copper in copper sulphate solution to become zinc sulphate and copper metal is formed
How does coating with another metal prevent corrosion?
when you coat a metal in another metal you are protecting the inside metal. The metal metal that is being used as a coat must be more corrosive than the 1st metal. For example iron can be coated in zinc because zinc is more corrosive than iron. This is common on a ship, the iron hull is coated with blocks of zinc which will act as a barrier and will corrode instead of the iron. The zinc blocks must be renewed after a period of time however. Other ways of stopping metals from corroding include, chromium plating, coating in paint, oil or plastic.
