From the balanced chemical equation,
                               4Fe + 3O₂ --> 2Fe₂O₃
it is evident that for every 4 moles of Fe (iron), 2 moles of iron (III) oxide will be formed. Using the same ratio, 
                               8 moles of iron x (2 moles Fe₂O₃ / 4 moles of Fe)
                                         = 4 moles Fe₂O₃
Therefore, the answer is 4 moles.

<u>Answer:</u> The correct answer is 4 moles.

<u>Explanation:</u>

For the given chemical reaction:

4Fe+3O_2\rightarrow 2Fe_2O_3

Oxygen from air is available which means it is present in excess. Iron is considered as a limiting reagent because it limits the formation of products.

By Stoichiometry of the reaction:

4 moles of iron produces 2 moles of iron oxide.

So, 8 moles of iron will produce = \frac{2}{4}\times 84mol of iron oxide.

Hence, the correct answer is 4 moles.

The overall equation for the cellular respiration of glucose is C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + energy. C5H12O6 + 6 O2 → 5 CO2
olga55 [171]

Answer:

The answer to your question is: first option.

Explanation:

C6H12O6 + 6 O2 → 6 CO2 + 6 H2O + energy.  This option is correct, 1 molecule of glucose reacts with 6 molecules of oxygen and produces 6 molecules of carbon dioxide, six molecules of water and energy.

C5H12O6 + 6 O2 → 5 CO2 + 6 H2O + energy. This option is incorrect because glucose has 6 carbons not five.

5 CO2 + 6 H2O → C5H12O6 + 6 O2 + energy. This is the reaction of photosynthesis, it is the inverse reaction of cellular respiration.

C6H12O6 + energy → 6 CO2+ 6 H2O + 6 O2. This reaction does not exist.

What does it mean for the energy levels in an atom to be quantized? Describe how this affects where electrons can be found.
olga55 [171]

Answer:

Energy of an electron is quantinized means the electrons can possess only specific individually separated values.

These energy levels are stable and are stationary along with different energy value.  The electron remains in the state until energy is absorbed or released.

The electrons absorb energy when it moves from lower energy state to higher energy state. The electrons lose energy when it moves from higher energy state to lower energy state and thus emit radiations corresponding to the energy gap and is called as quanta.
