How many grams of C are required to react with 64.6 g of Fe2O3 ?

Chemistry

4 0

Answer:

14.6 g

Explanation:

Fe₂O₃  +  3 C  →  2 Fe  +  3 CO₃

First, convert grams of Fe₂O₃ to moles.  The molar mass is 159.69 g/mol.

(64.6 g)/(159.69 g/mol) = 0.4045 mol

Now, use stoichiometry to convert moles of Fe₂O₃ to moles of C.  By looking at the chemical equation, you can see that for every 1 mole of Fe₂O₃, you need 3 moles of C.  Use this relationship.

(0.4045 mol Fe₂O₃) × (3 mol C/1 mol Fe₂O₃) = 1.214 mol C

Now, convert moles of C to grams.  The molar mass is 12.01 g/mol.

(1.214 mol C) × (12.01 g/mol) = 14.58 g

You need to use significant figures.

14.58 g ≈ 14.6 g

What are the limitations of the Klmn electronic configuration style of writing
Salsk061 [2.6K]

In the KLMN electronic configuration style of writing K denotes the first shell which can hold up to two electrons, L denotes the second shell which can hold up to eight (2 + 6) or 8 electrons, M denotes the third shell which can hold up to eight (2 + 6 + 10) or 18 electrons etc.

The KLMN style of writing  only indicates the number of electrons in each principal quantum number, however the spdf electronic configuration style of writing subdivides each shell into its subshells.

For instance the 3rd principal quantum number has s,p and d subshells, wherein s, p and d orbitals can have a maximum of 2, 6 and 10 electrons respectively.

The density of a 1 milliter sample of water is 1 gram. express this density in milligrams per liter
sergeinik [125]

The correct answer is 1000 Kg/M³

Density of water =1-g/cm3.

We know 1- g= 10^-³ Kg

cm³ =(10^-2)³= 10^-6

Substituting we get

Density of water

= 1 x (1x10^-³)/10^-6 Kg/M³

= 1x10^3 = 1000 Kg/M³

<h3>what is density?</h3>

Density is the mass of a material substance per unit volume. Density is defined as d = M/V, where d represents density, M is mass, and V is volume. Density is generally measured in grammes per cubic centimetre. Water, for example, has a density of 1 gramme per cubic centimetre, but Earth has a density of 5.51 grammes per cubic centimetre. Density is sometimes measured in kilos per cubic metre (in metre-kilogram-second or SI units). The density of air, for example, is 1.2 kilogrammes per cubic metre. Textbooks and handbooks list the densities of common solids, liquids, and gases.
