Is Surface tension of water affected by potassium permanganate?
Yes. Surface tension of water increases with addition of potassium permanganate.
How do you convert lead nitrate to metallic lead?
If you have a solution of Lead nitrate, place some zinc, or iron into it and the metals will displace.Zn(s) + PbNO3(aq) → ZnNO3(aq) + Pb(s)Any metal that is more reactive than lead, such as tin, nickel, iron, manganese, aluminum, magnesium, sodium, calcium, barium, potassium, lithium. That order is in order from least reactive to most reactive. Note that the more reactive it is the faster and more exothermic (heat produced) the reaction will be. I would personally use aluminum as you can get foil which is thin (large surface area) and much more reactive.
What is a word that means science that records facts about the earths surface?
The science which records facts about the Earth's surface is called geology.
Which metal is preserved in kerosine?
sodium and potassium are kept under kerosene surface to protect them from rust since the are very active elements and react with O as soon as being exposed to it.
What is the science that records facts about the earths surface?
Geography
What are some interesting uses of the science of electrolysis?
The science of electrolysis is used in the production of aluminum, potassium, chlorine, and magnesium. Electrolysis is also used in anodization, a process which makes the surface of metals resistant to corrosion.
Is Surface tension of water affected by potassium permanganate?
Yes. Surface tension of water increases with addition of potassium permanganate.

Does potassium have little or no shine?
The fresh surface has a silvery aspect.
What metals can be stored in oil?
All of the 1st group metals (Li, Na, K, Rb, Cs, Fr) because they react with the air and many other things.
What are the two types of surface science?
earth and life science
What happens when potassium react to water?
When potassium reacts with water the potassium burns a bright purple light, a gas is given off with a hissing noise and the potassium rockets around the surface of the water because it floats.
What happens to potassium in water?
It reacts violently, fizzes about on the surface and then: BOOM!!!

Is carbon dioxide reactive to metal surfaces particularly Nb surface and could adsorbed heavily?
Carbon dioxide is not so reactive with metals; any reaction with niobium.
