How many moles of Cl2 are needed in order to produce 100.0 grams of FeCl3 given the following
dimulka [17.4K]

Answer:

0.92moles

Explanation:

Given reaction:

              2Fe + 3Cl₂ →  2FeCl₃

Mass of FeCl₃  = 100g

Unknown:

Number of moles of Cl₂  needed = ?

Solution:

To solve this problem, we work from the known specie to the unknown.

From the mass of the FeCl₃ given, we can solve for the number of moles of the unknown.

  • Number of moles of FeCl₃;

  Number of moles  = \frac{mass}{molar mass}  

  Molar mass of  FeCl₃ = 56 + 3(35.5) = 162.5g/mol

   Number of moles  = \frac{100}{162.5}  = 0.62mole

From the reaction expression;

           2 mole of FeCl₃ is produced from 3 moles of  Cl₂  

           0.62 mole of FeCl₃ will be produced from \frac{0.62 x 3}{2}   = 0.92mole

The number of moles of Cl₂  = 0.92moles

I have 26 protons,26 electrons, and 30 neutrons?
Amiraneli [1.4K]

Answer:

Iron (Fe)

Explanation:

# of protons is the atomic number of the element

the element with the atomic number 26 is Iron

with 26 electrons this means it is Iron with no charge

with 30 neutrons this means the atomic weight will be

26 (protons) + 30 (neutrons) = 56

the real atomic weight of iron listed on the periodic table is 55.845, this rounded up is 56.
