is ice  a  mineral?.....glacial    oxide  of   hydrogen?

Yes, if it forms naturally it is a mineral. The name is just ice. There isn't any 'glacial' part, although that does add to the description. Liquid water is NOT a mineral because it is liquid, and man-made ice is not a mineral because it is man-made. It is hydrogen oxide. \n\nHere's a good definition of a mineral: (I quote)\n"To be classified as a "true" mineral, a substance must be a solid and have a crystal structure. It must also be an inorganic, naturally-occurring, homogeneous substance with a defined chemical composition."\n\nIce is solid. It has a crystal structure. It is inorganic. It is naturally-occurring, and it is only made of one thing, H20, so it fits the definition well.

In my opinion calcium is inorganic. It is a mineral rather than an organism.

The simple answer is solid, liquid and gaseous, the same as all other materials. However, if one wants to probe a bit deeper:\n\n1. One can imagine that if the water were subjected to extreme conditions, that it could form a plasma, the fourth state of matter. \n\n2. There are many forms of the solid version of water, ice:\n\na. the simplest crystalline phase of ice is hexagonal, also known as Ih\n\nb. under different conditions, other crystalline phases exist, known as II, III, V, VI, VII, VIII, IX and X. \n\nc. ice can also exist in amorphous states, amorphous solid water (ASW), low density amorphous ice (LDA), high density amorphous ice (HDA), very high density amorphous ice (VHDA) and hyperquenched glassy water (HGW).\n\nd. ice can also form a clathrate hydrate, in which gas molecules are trapped in an ice crystal lattice (deep on the ocean floor, on the outer planets in the solar system possibly, inside arctic gas pipelines).\n\nAnd these are just the ones we have found so far. Depending on what you call a "phase", there are many, many phases of water.

My friend did one that answered the question : "Which melts ice faster: Salt or spices?"\n\nShe experimented with salt and spices like cinnimon, peprika, chili powder, red pepper...\n\nIt was pretty cool. The title we came up with was "Salt or Spice Melts the Ice?" \n\nSalt melted it the fastest.

Hydrogen.  Normally it is a gas at room temperature, and takes extreme cryogenic cold just to make it a liquid, but guess what?\n\nAt a few millionths of a degree above absolute zero, where Helium gas goes liquid, Hydrogen gas actually freezes...and when it does, it arranges itself so that it is physically *metallic*.\n\nAnd yes, this has been tested outside of an earthly laboratory, way outside....\n\nGo to Space.com, do a search on the phrases "core of Jupiter" and "meteor strikes"....a few years ago, a meteor shower hit Jupiter with some fairly large space rocks, and we had radio and satellite telescopes trained on the event....\n\nAnd there was a hypothesis that the core of Jupiter was cold enough and under enough pressure from gravity to be metallic hydrogen...the idea was simple enough, if the core was metallic hydrogen, then when the meteors hit it, it should ring like metal, not just acoustically, but electro-magnetically too, in a predictable way....\n\nAnd.  It.  Did.

Yes. It is called lime or quick lime and this is basic in nature.\n\nEXTRA: Calcium hydroxide is a chemical compound with the chemical formula Ca(OH)2. It is a colorless crystal or white powder, and is created when calcium oxide (called lime or quicklime) is slaked with water. It can also be created by mixing an aqueous solution of calcium chloride and an aqueous solution of sodium hydroxide. A traditional name for calcium hydroxide is slaked lime, or hydrated lime.\n\nIf heated, calcium hydroxide decomposes into calcium oxide and water. A suspension of fine calcium hydroxide particles in water, called lime water (or milk of lime), is a medium strength base that reacts violently with acids and attacks many metals in presence of water.

Water vapor that has frozen.\nTidbit: Snow doesn't melt - it vaporizes, turning back into vapor as it heats up.

It all depends on the exact composition of air. Air is a mixture of gasses, Nitrogen, Oxygen, Carbon Dioxide, Carbon monoxide and small amounts of various other gasses. Freezing occurs when the gaseous mixture turns from a liquid and then into a solid. Although it may theoretically be possible to solidify Air, it has not actually been reached.

The polarity is what makes the atoms in the H2O molecule stick together if not for that then there would be no water, meaning no life except bacteria, and no us. I think that is pretty important. \n Also it can dissolve most anything. \nThere is high latent heat of fusion  meaning it needs a lot of heat removal before it changes to ice= does not freeze very quickly therefore giving us drinkable water and grow crops and everything else. \nThere is high heat capacity. IT needs a lot of heat or energy before it vaporizes therefore it does not vaporize quickly and turn in steam during hot seasons and months leaving us again with no water.\nThere is high surface tension. Therefore it allows most things on it to float since water has a high density. Ice can float on it during freezing seasons. If ice did not float it would go to the bottom and freeze all the marine life like fish and plants.

The answer is either 0% or 100%. If ice is 0 degrees C it will remain as ice. [in theory]

Methane clathrate, also called methane hydrate or methane ice, is a form of water ice that contains a large amount of methane within its crystal structure (a clathrate hydrate). Originally thought to occur only in the outer regions of the solar system where temperatures are low and water ice is common, extremely large deposits of methane clathrates have been found under sediments on the ocean floors of Earth. Methane clathrates are common constituents of the shallow marine geosphere, and they occur both in deep sedimentary structures, and as outcrops on the ocean floor. Methane hydrates are believed to form by migration of gas from depth along geological faults, followed by precipitation, or crystallization, on contact of the rising gas stream with cold sea water.\n\nMethane clathrates remain stable at temperatures up to 18 °C. The average methane clathrate hydrate composition is 1 mole of methane for every 5.75 moles of water, though this is dependent on how many methane molecules "fit" into the various cage structures of the water lattice. The observed density is around 0.9 g/cm3. One liter of methane clathrate solid would therefore contain, on average, 168 liters of methane gas (at STP).\n\nMethane forms a structure I hydrate with two dodecahedral (20 water molecules) and six tetrakaidecahedral (24 water molecules) water cages per unit cell. The hydratation value of 20 can be determined experimentally by MAS NMR (Dec, 2005). A methane clathrate spectrum recorded at 275 K and 3.1 MPa shows a peak for each cage type and a separate peak for gas phase methane.\n\nNatural deposits\nMethane clathrates are restricted to the shallow lithosphere (i.e. <2000m depth). Furthermore, necessary conditions are found only either in polar continental sedimentary rocks where surface temperatures are less than 0°C; or in oceanic sediment at water depths greater than 300m where the bottom water temperature is around 2°C. Continental deposits have been located in Siberia and Alaska in sandstone and siltstone beds at less than 800m depth. Oceanic deposits seem to be widespread in the continental shelf (see Fig.) and can occur within the sediments at depth or close to the sediment-water interface. They may cap even larger of deposits of methane gas (Kvenvolden, 1995).\n\nOceanic\nThere are two distinct types of oceanic deposit. The most common is dominated (>99%) by methane contained in a structure I clathrate and generally found at depth in the sediment. Here, the methane is isotopically light (δ13C < -60‰) which indicates that it is derived from the microbial reduction of CO2. The clathrates in these deep deposits are thought to have formed in-situ from the microbially-produced methane, as the δ13C values of clathrate and surrounding dissolved methane are similar (Kvenvolden, 1995).\n\nThese deposits are located within a mid-depth zone around 300-500m thick in the sediments (the Gas Hydrate Stability Zone, or GHSZ) where they coexist with methane dissolved in the pore-waters . Above this zone methane is only present in its dissolved form at concentrations that decrease towards the sediment surface. Below it, methane is gaseous. At Blake Ridge on the Atlantic continental rise, the GHSZ started at 190m depth and continued to 450m, where it reached equilibrium with the gaseous phase. Measurements indicated that methane occupied 0-9% by volume in the GHSZ, and ~12% in the gaseous zone (Dickens, 1997).\n\nIn the less common second type found near the sediment surface some samples have a higher proportion of longer-chain hydrocarbons (<99% methane) contained in a structure II clathrate. Methane is isotopically heavier (δ13C is -29 to -57 ‰) and is thought to have migrated upwards from deep sediments where methane was formed by thermal decomposition of organic matter. Examples of this type of deposit have been found in the Gulf of Mexico and the Caspian Sea (Kvenvolden, 1995).\n\nSome deposits have characteristics interm

Of course ice and water are chemically identical consisting of H2O.  The two hydrogen atoms attach to the oxygen atom other than in a straight line (not like beads on a string).  The electron field surrounding the water molecule is uneven providing it with a "polarity" that makes it much easier to pack many molecules together in a given (rather than arbitrary) arrangement.  When water is a vapor (or steam) there is so much vibrational energy that the molecules bounce off each other maintaining a "pressure" depending on their energy (temperature).  When the molecules are a liquid, they are very closely packed and are nearly incompressible (even seven miles below the surface of the ocean!).  The bulk water expands and contracts only a little with temperature changes.  When heat is removed from the water (in a freezer?) the molecules are attracted to each other in a preferred array due to polarity and form long chains of molecules that use up space far less efficiently.  The "ice" is less dense and floats on water because the space between chains is filled with a vacuum or gases that weigh very little.  When the water is allowed to freeze in open space (a cloud?) the polarity is free to align water molecules in the most preferred orientation; a six sided snow flake.  When hoar frost forms on a cold window pane the ice forms in dendrites, like growing Christmas trees.  Hope that helps a little.

Yes, diamond, graphite, and its relatives are all inorganic. A more specific definition of an organic compound is something that contains both carbon and hydrogen atoms.

Air is composed of eight or so chemical molecues and combines to create a gas. Water is composed of hyrogen and oxygen molecues and exists as a liquid or solid state (ice).  The difference in density of comparing a gas to a liquid is that the gas is less dense than the liquid, therefore offering less resistance to your hand.

Do not offer bribes, this is immoral.\nMany here come to assist as a service.\n\nYour answer is here:\n\nWhen ice melts, kinetic energy of H2O molecules is increased by absorption of heat energy from the surroundings.\n\nHowever as the kinetic energy is increased to make the molecules move freely, Hydrogen Bonding among the water molecules becomes more effective and so a particular intermolecular distance is maintained among the molecules. \n\nThis is effective upto 4C.\n\nAfter 4C the H-bonding becomes so week as against kinetic energy that free movement of molecules is no more restricted and thus abnormal behaviour of water molecules is stopped.
