How can a chemical equation of sodium phosphate reacting with calcium nitrate to produce sodium nitrate and calcium phosphate be balanced?
2Na3PO4 + 3Ca(NO3)2 --> 6NaNO3 + Ca3(PO4)2
How do you get potassium nitrate out of a mixture with calcium carbonate?
calcium carbonate+ nitric acid. a strong acid would replace a weaker acid in most ionic compounds, so you would produce calcium nitrate and carbon dioxide. well, being that nitric acid is widely UNAVAILABLE to most people, it is easy to find potassium or sodium nitrate. if you are going specifically for calcium nitrate you can double displace calcium carbonate with potassium or sodium nitrate resulting in potassium or sodium carbonate and (aq) calcium nitrate. the potassium or sodium carbonate will probably precipitate out much quicker than the nitrate depending on how exact your equation for displacement is. and you should be left with (aq) calcium nitrate. boil off the water and preferably recrystallize for purity. if youre using calcium carbonate just to get any form of nitrate, i recommend simply buying potassium nitrate. if it is not assessable in your area and are trying to get an oxidizer ( i assume thats why you are trying to make a nitrate) i recommend going with a chlorate or perchlorate, these are easier to make at home through electrolysis.
Calcium oxide plus nitric acid?
you get carbon dioxide if you mix any acid with a carbonate aswell as water and calcium nitrate. 2HNO3(aq) + CaCO3(s) = Ca(NO3)2(s) + H2O(l) + CO2(g) Ca is a 2+ ion, and the NO3 is only a - ion, therefore two are needed! this balances the equation.
Will a nichrome wire light up when heated?
Nichrome is a name for a nickel- chromium resistance wire, a nonmagnetic alloy of nickel and chromium. Common alloy is 80% nickel and 20% chromium, by weight. Silvery-grey in colour, corrosion resistant and has a high melting point of 1400 C (2552 F). Due to it's high resistivity and resistance to oxidation at high temperatures, it's widely used in heating elements, such as in hair dryers, electric ovens and toasters. Typically, Nichrome is wound in wire coils to a certain electrical resistance, and current passed through to produce heat. For heating, resistance wire must be stable in air when hot. Nichrome wire forms a protective layer of chromium oxide. Kimber :)
What are chemical properties of stainless steel?
Pure iron (Fe), mixed with carbon to produce 'steel', Chromium is added to steel to make it resistant to rust. copper, Titanium annd vanadium are the alloys which make it more suitable for specific uses,
What acid would react with chromium to produce chromium chloride?
I think its hydroclauric acid or however you spell it.. Think..
Is chromium ferrous?
Chromium does not occur freely in nature. The main chromium mineral is chromite. Chromium compounds can be found in waters only in trace amounts. Many chromium compounds are relatively water insoluble. Chromium (III) compounds are water insoluble because these are largely bound to floating particles in water. Chromium (III) oxide and chromium (III) hydroxide are the only water soluble compounds.Chromium (VI) oxide is an example of an excellently water soluble chromium compounds
Chromium iii oxide reacts with hydrogen sulfide h2s gas to form chromium iii sulfide and water how many grams of cr2o3 are required to produce 421 g of cr2s3?

When Chromium is alloyed with steel what type of steel is produce?
It depends on the chromium content. If it is 13% or more, it creates stainless steel. Any less then that would still be considered as high carbon, tool steel, etc.
How much chromium did the U.S. produce in 2002?
Domestically, production of chromium declined from 139,000 metric tons to 129,000 metric tons between 2002 and 2003 as imports increased from 263,000 metric tons to 344,000 metric tons
Who locates the diamond deposits?
Geologists hold the appropriate expertise for locating the volcanic pipes that can produce diamonds. Common indicator minerals, such as: ". . . chromium garnets (usually bright red chromium-pyrope, and occasionally green ugrandite-series garnets), eclogitic garnets, orange titanium-pyrope, red high-chromium spinels, dark chromite, bright green chromium-diopside, glassy green olivine, black picroilmenite, and magnetite.. . ." can lead the geologist to the pipe.
What are some uses for chromium?
Chromium, a blue white metal is put to use for industrial purposes. It is used in tanning leather, harden steel and also to produce stainless steel. Sometimes they are also used catalysts and corrosion-resistant materials.
How many grams of chromium (III) chloride are required to produce 75.0 g of silver chloride?
The formula of chromium chloride is CrCl3 and the formula for silver chloride is AgCl. The relevant formula unit masses are 158.36 for chromium (III) chloride and 143.32 for silver chloride. The gram atomic masses of chlorine, chromium, and silver are 35.453, 51.996, and 107.866 respectively. Therefore, the mass fraction of chloride in chromium (III) chloride is [3(35.453)/158.36] or 0.671628 and the mass fraction of chloride in silver chloride is 35.453/143.32 or 0.24737. Therefore, to form 75.0 g of silver chloride, (0.24737)(75.0) or 18.55 g of chloride is needed, and this amount of chloride is contained in 18.55/0.6716 or 27.6 g of chromium (III) chloride, to the justified number of significant digits.

What are chromiums uses?
Chromium is a chemical element which has the symbol Cr and atomic number 24, first element in Group 6. It is a steely-gray, lustrous, hard metal that takes a high polish and has a high melting point. It is also odorless, tasteless, and malleable. The name of the element is derived from the Greek word "chrōma" (χρώμα), meaning colour, because many of its compounds are intensely coloured. It was discovered by Louis Nicolas Vauquelin in the mineral crocoite (lead chromate) in 1797. Crocoite was used as a pigment, and after the discovery that the mineral chromite also contains chromium this latter mineral was used to produce pigments as well.Chromium was regarded with great interest because of its high corrosion resistance and hardness. A major development was the discovery that steel could be made highly resistant to corrosion and discoloration by adding chromium to form stainless steel. This application, along with chrome plating (electroplating with chromium) are currently the highest-volume uses of the metal. Chromium and ferrochromium are produced from the single commercially viable ore, chromite, by silicothermic or aluminothermic reaction or by roasting and leaching processes. Although trivalent chromium (Cr(III)) is required in trace amounts for sugar and lipid metabolism, few cases have been reported where its complete removal from the diet has caused chromium deficiency. In larger amounts and different forms chromium can be toxic and carcinogenic. The most prominent example of toxic chromium is hexavalent chromium (Cr(VI)). Abandoned chromium production sites often require environmental cleanup.Posted by chemistry manual at 9:26 AM
