To determine the amount of chromium (III) oxide (Cr2O3) needed to produce 421 g of chromium (III) sulfide (Cr2S3), you need to consider the molar ratio of the reactants. The molar mass of Cr2S3 is 256.16 g/mol, and Cr2O3 has a molar mass of 151.99 g/mol. First, calculate the moles of Cr2S3 produced from 421 g. Then, use the molar ratio from the balanced chemical equation to find the moles of Cr2O3 needed, and convert this to grams.

What acid would react with chromium to produce chromium chloride?
Hydrochloric acid would react with chromium to produce chromium chloride according to the following equation: 2 Cr(s) + 6 HCl(aq) → 2 CrCl3(aq) + 3 H2(g)
Is chromium used as fuel nuclear power plants?
No, chromium is not used as a fuel in nuclear power plants. In nuclear power plants, the most common fuel is uranium, which undergoes fission reactions to generate heat that is used to produce electricity. Chromium is mainly used in stainless steel components within the nuclear reactors for their corrosion resistance properties.
How much chromium did the U.S. produce in 2002?
The U.S. produced approximately 103,000 metric tons of chromium in 2002.
What element combined with nickel it forms nichrome wire which is used in toasters and other devices where high elctrical resistances is desire to produce heat?
Chromium is the element that combined with nickel to form nichrome wire. The addition of chromium increases the wire's electrical resistivity, making it ideal for applications where high heat generation is needed, such as in toasters.
When Chromium is alloyed with steel what type of steel is produce?
When chromium is alloyed with steel, it produces stainless steel. Stainless steel is known for its corrosion resistance and various applications in industries such as construction, food processing, and medical devices.
What acid would react with chromium to produce chromium chloride?
Hydrochloric acid would react with chromium to produce chromium chloride according to the following equation: 2 Cr(s) + 6 HCl(aq) → 2 CrCl3(aq) + 3 H2(g)
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
What transition metal do you add to iron to get bright shiny steel?
To produce bright shiny steel, chromium is added to iron. Chromium improves the corrosion resistance of steel and gives it a shiny appearance.
How many miles of calcium nitrate would react with 4.55 moles of Chromium (III) sulfate to produce chromium (III) nitrate?
To determine how many miles of calcium nitrate would react with 4.55 moles of Chromium (III) sulfate to produce chromium (III) nitrate, you would first need to write the balanced chemical equation for the reaction between calcium nitrate and chromium (III) sulfate. Then, use the stoichiometry of the reaction to convert moles of Chromium (III) sulfate to moles of calcium nitrate, and finally, convert moles of calcium nitrate to miles using the molar mass.
How many grams of copper would be produced from 49.48 g of chromium?
Chromium cannot be directly converted to copper. They are different elements with different atomic numbers and properties. You would need a chemical reaction involving copper ions to produce copper from chromium.
Is chromium used as fuel nuclear power plants?
No, chromium is not used as a fuel in nuclear power plants. In nuclear power plants, the most common fuel is uranium, which undergoes fission reactions to generate heat that is used to produce electricity. Chromium is mainly used in stainless steel components within the nuclear reactors for their corrosion resistance properties.
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.
How many grams of chromium III chloride are required to produce 75.0 g of silver chloride?
To find the amount of chromium III chloride required to produce 75.0 g of silver chloride, you need to consider the stoichiometry of the reaction. Calculate the molar mass of AgCl (molar mass of Ag + molar mass of Cl) to determine the moles of AgCl produced. From the balanced chemical equation, determine the mole ratio between AgCl and CrCl3. Finally, convert moles of AgCl to moles of CrCl3 and then to grams of CrCl3 using its molar mass.

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.
