Yes, gold can float in a molten vat of lead because gold is less dense than lead. When molten, materials with lower density will float on top of materials with higher density. This property allows for the separation of gold from lead in a process called cupellation.
the solids that will float on liquid mercury are coal, ironware's or objects with lower specific density
Several are such as lead, but mercury (the only metal that is a liquid at room temperature) is very poisonous.
Lead has atomic number 82, if it loses 2 protons and 2 neutrons (ie an alpha particle) it becomes mercury with atomic number 80. Only lead-204 (1.4 percent of natural lead) and lead-210 (trace only) appear to do this, and 204 has such a long half life that it is regarded as stable, so your postulated reaction does not seem to be typical of lead as a whole.
Of the three, only mercury (a liquid metal) is heavier than water and would sink to the bottom. Gasoline is partly miscible (forms suspensions in water), while turpentine has a lower density than water and would float on top.
A block of aluminum will float on a pool of mercury at nearly any temperature (except at extremely elevated temperatures (above 350 °C) where mercury is no longer liquid) The density of aluminum is 2.70 grams per cm3, whereas the density of mercury is 13.53 grams per cm3. Therefore mercury is more than 5 time more dense than aluminum! Anything that is less dense than a liquid will float in that liquid. Not only would aluminum float but it float with only 1/5 of it's volume submerged.
Most materials will float in Mercury because it is so dense. A lump of Lead will float in a bath of Mercury. The well-known metals Gold, Platinum, Tungsten, Uranium and Plutonium are more dense than mercury and would sink. More specifically, any material having a density less than 13593 Kg/m3 will float in a bath of Mercury.
Stones do not float in mercury because mercury is a very dense liquid, much denser than a stone. Any object denser than mercury will sink in it. In general, objects float in a liquid only if they are less dense than the liquid.
Just about anything that is lighter then mercury. Dont be tempted to put your gold ring on mercury as it will dissolve in it, and let of a toxic gas while doing so Iron, water, sand, lead, wood, All the things that are lighter then Mercury.
No, the only thing that can block X-rays is a sheet of lead.
Yes, a block of wood would typically float on top of water because wood is less dense than water. This means that the weight of the wood is less than the weight of the water it displaces, causing it to float.
Yes, gold can float in a molten vat of lead because gold is less dense than lead. When molten, materials with lower density will float on top of materials with higher density. This property allows for the separation of gold from lead in a process called cupellation.
no, mercury is a substanable resource meaning non waterised substance so cannot float in water No, mercury is heavier than water. It can't float in water. It is actually a metal that is liquid at room temperature and for several degrees around that. That's why it's used in thermometers.
Both lead and mercury are metals, physically lead is solid at room temperature, however mercury is a liquid, but chemically they are both metals. Mercury is a classified as a transition metal, however technically isn't as it doesn't not have a partially filled d-orbital in either it elemental state or as one of it's common ions. Lead on the other hand belongs to the group known as the poor metals.
Mercury is the only one of the four metals that's a liquid at room temperature. The others are solids.
