Answer:

a. Fe₂(SO₄)₃  + 6 KOH  →  3 K₂SO₄  +   2Fe(OH)₃

b. 2 mol of KOH

c. 8 mol of Iron(II) hydroxide

Explanation:

This is the balanced reaction

Fe₂(SO₄)₃  + 6 KOH  →  3 K₂SO₄  +   2Fe(OH)₃

b. Ratio is 3:6 so,

For 3 mol of potassium sulfate, I needed 6 mol of KOH

For 1 mol of potassium sulfate I would need (1 .6 )/3 = 2 mol of KOH

c. 1 mol of iron(III) sulfate, produce 2 mol of Iron(II) hydroxide

4 mol of iron(III) sulfate, will produce (4x2), 8 mol of Iron(II) hydroxide

Answer:

a) Fe2(SO4)3 + 6KOH → 3K2SO4 + 2Fe(OH)3

b) <u>2 moles of KOH</u>

<u>c) 8 moles of Fe(OH)3 </u>

Explanation:

Step 1: The balanced equation

Fe2(SO4)3 + 6KOH → 3K2SO4 + 2Fe(OH)3

Step 2: Data given

Molar mass of K2SO4 = 174.26 g/mol

Molar mass of KOH = 56.11 g/mol

Molar mass of Fe(OH)3 = 106.87 g/mol

Molar mass of Fe2(SO4)3 = 399.88 g/mol

How many mole of potassium hydroxide (KOH) would be needed to create 1 mole of K2SO4 ?

Step 3: Calculate moles of potassium hydroxide (KOH)

For 1 mol Fe2(SO4)3 we need 6 moles of KOH to produce 3 moles of K2SO4 and 2 moles of Fe(OH)3

To produce 1 mol of K2SO4 we need 2*1 = <u>2 moles of KOH</u>

How many mole of Fe(OH)3, would be produced from reacting 4 mole of Fe2(S04)3 ?

Step 4: Calculate moles of Fe(OH)3

For 1 mol Fe2(SO4)3 we need 6 moles of KOH to produce 3 moles of K2SO4 and 2 moles of Fe(OH)3

When 4 moles of Fe2(SO4)3 will be consumed, there will be produced 2*4 =<u> 8 moles of Fe(OH)3 </u>

In a reaction, chlorine accepts an electron to form Cl-. What is true about the atomic size of the chlorine ion?
Lynna [10]

Answer is: The atomic size of the chlorine ion is larger than the size of the chlorine atom.

Covalent radii of chlorine atom (Cl) is 0.099 nm and ionic radii of chlorine anion (Cl⁻) is 0.181 nm.

Difference between an chlorine atom and chlorine anion is the number of electrons that surround the nucleus.

Chlorine atom has 17 electrons and chlorine anion has 18 electrons.

Which reaction is a decomposition reaction?
Artist 52 [7]

Answer:

See the answer below , please.

Explanation:

In a decomposition reaction, a certain compound is "broken" to give two or more different products.

An example for compound AB, giving as products A and B:

AB -> A + B

In the case of water:

2H20 -> 2H2 + 02,  water decomposes giving Hydrogen and Oxygen
