If 279 grams of iron react with an excess of oxygen, as shown in the balanced equation below, how many grams of iron (iii) oxide
dsp73

Answer:-

399 gram

Explanation:-

The balanced chemical equation for the reaction is

4Fe +3 O2 --> 2 Fe2O3

Atomic mass of Iron Fe is 55.845 gram

Molecular mass of Iron (III) Oxide Fe2O3 is

55.845 x 2 + 16 x 3 = 159.69 gram

From the balanced chemical equation,

4 Fe gives 2 Iron (III) oxide

∴ 4 x 55.845 grams of Fe gives 2 x 159.69 grams of Iron (III) Oxide.

279 grams of Fe gives (2 x 159.69) x 279 / ( 4 x 55.845)

= 399 gram

Calculate the mass of iron(III) oxide that contains a million iron atoms. Be sure your answer has a unit symbol if necessary, an
KiRa [710]

<u>Answer:</u> The mass of iron (II) oxide that contains a million iron atoms is 2.6\times 10^{-17}g

<u>Explanation:</u>

We are given:

Number of iron atoms = A million = 1.0\times 10^6

The chemical formula of the given compound is Fe_2O_3

It is formed by the combination of 2 iron atoms and 3 oxygen atoms.

According to mole concept:

1 mole of a compound contains 6.022\times 10^{23} number of particles

1 mole of iron (II) oxide will contain = (2\times 6.022\times 10^{23})=1.2044\times 10^{24} number of iron atoms

We know that:

Molar mass of iron (II) oxide = 159.7 g/mol

Applying unitary method:

For 1.2044\times 10^{24} number of iron atoms, the mass of iron (II) oxide is 159.7 g

So, for 1.0\times 10^6 number of iron atoms, the mass of iron (II) oxide will be \frac{159.7}{1.2044\times 10^{24}}\times 1.0\times 10^6=2.6\times 10^{-17}g

Hence, the mass of iron (II) oxide that contains a million iron atoms is 2.6\times 10^{-17}g

Why is H2SO4 regarded as an ampholyte
Vanyuwa [196]
I think sulfuric acid cannot be regarded as an ampholyte. Ampholytes are amphoteric molecules or that contains both acidic and basic groups. An amphoteric compound can react both as an acid and a base which sulfuric acid is not capable.
