A chromium oxide compound contains 104.0 g of chromium and 48.0 g of oxygen. what is the most likely empirical formula of this compound?
To find the empirical formula, we need to determine the ratio of atoms present in the compound. First, convert the masses of chromium and oxygen to moles. The mole ratio will be approximately 2:3, indicating the compound is most likely chromium(III) oxide with the empirical formula Cr2O3.
Consider the following balanced equation Fe203 plus 3H2 gives 2Fe plus 3H2O What mass of hydrogen would be required to convert 160g of iron III oxide into iron?
6g hydrogen would be required for 160g ferric oxide in this reaction. The relative atomic weights of the elements are: Hydrogen - 1 Oxygen - 16 Iron - 56 giving the relative atomic weights of the compounds (on the left of the equation): Fe2O3 = 56×2 + 16×3 = 160 3H2 = 3×(1×2) = 6 So for every 160 units of mass of iron III oxide there will be 6 units of mass of hydrogen required. → for 160g of iron III oxide ÷ 160 × 6 = 6 g of hydrogen.
What is the formula of Chromium (II) oxide?
The formula of Chromium (II) oxide is CrO.
What ions are present in chromium III oxide?
Chromium oxide is the light green inorganic compound coCr203. When dissolved in acid, it produces the hydrated chromium ions [Cr(H2O)6]3+.
When 127 g of copper reacts with 32 g of oxygen gas to form copper (II)oxide no copper or oxygen is left over. how much copper (II) oxide is produced?
Using the given masses, calculate the moles of each reactant. The limiting reactant will be the one that produces the least amount of product, which is copper. Convert the moles of copper to moles of copper (II) oxide using the balanced chemical equation. Then, convert the moles of copper (II) oxide to grams to find the mass produced.
Is Cr2O3 inorganic?
Yes, Cr2O3 (chromium(III) oxide) is an inorganic compound. It is a metal oxide composed of chromium and oxygen, and it does not contain carbon-hydrogen bonds typically found in organic 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?
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 is the compound name for Cr2O?
chromium oxide
