What mass of Fe(OH)3 will be obtained when 100. mL of 0.240 M FeCl3 is mixed with 200. mL of 0.182 M NaOH?
ratelena [41]

Answer:

648.68 mg

Explanation:

The reaction that takes place is:

  • FeCl₃ + 3NaOH → Fe(OH)₃ + 3NaCl

First we<u> calculate how many moles of each reactant were added</u>, using the <em>given volumes and concentrations</em>:

  • FeCl₃ ⇒ 100 mL * 0.240 M = 24 mmol FeCl₃
  • NaOH ⇒ 100 mL * 0.182 M = 18.2 mmol NaOH

24 mmol of FeCl₃ would react completely with (24 * 3) 72 mmol of NaOH. There are not as many NaOH mmoles, so NaOH is the limiting reactant.

Now we <u>calculate how many moles of Fe(OH)₃ are formed</u>, using the <em>moles of the limiting reactant</em>:

  • 18.2 mmol NaOH * \frac{1mmolFe(OH)_3}{3mmolNaOH} = 6.07 mmol Fe(OH)₃

Finally we <u>convert 6.07 mmol Fe(OH)₃ to grams</u>, using its<em> molar mass</em>:

  • 6.07 mmol Fe(OH)₃ * 106.867 mg/mmol = 648.68 mg

Electrons are emitted from a conductor when the conductor is
givi [52]
<span>Electrons, the negatively charged particles that carry electricity in metals, can be ejected from the material if it is bombarded by a large number of high-speed electrons. This effectively, leads to some metallic electrons being "knocked" out of the material. </span>

B. from 52 moles of nitric acid, how many moles of silver nitrate will be produced?
IceJOKER [234]

Answer:

39 mol AgNO3

Explanation:

We have the equation 4HNO3 + 3Ag -----> 3AgNO3 + NO + 2H2O

We want to calculate the number of silver nitrate (AgNO3) moles that would be produced from 52 moles of nitric acid ( HNO3 )

We can calculate this by using mole ratio as well as dimensional analysis.

The mole ratio of Silver nitrate to nitric acid based on the balanced equation is 3AgNO3:4HNO3.

Using this we can create a table: The table is attached.

Breakdown of the table.

The moles of nitric acid cancel out and we multiply 52 by 3/4 to get 39 moles of Silver nitrate.
