Limiting Reactant problem

Chemistry
1 answer:
melomori [17]3 years ago
3 0

Answer:

Since ethane is the limiting reactant. It will completely be consumed. There will remain 0 grams of ethane.

Explanation:

Step 1: Data given

Mass of C2H6 = 20.1 grams

Mass of O2 = 95.0 grams

Molar mass ethane = 30.07 g/mol

Molar mass O2 = 32.0 g/mol

Molar mass CO2 = 44.01 g/mol

Step 2: The balanced equation

2C2H6 + 7O2 → 4CO2 + 6H2O

Step 3: Calculate moles C2H6

Moles C2H6 = mass C2H6 / molar mass C2H6

Moles C2H6 = 20.1 grams /30.07 g/mol

Moles C2H6 = 0.668 moles

Step 4: Calculate moles O2

Moles O2 = 95.0 grams / 32.0 g/mol

Moles O2 = 2.97 moles

Step 5: Calculate limiting reactant

For 2 moles C2H6 we need 7 moles O2 to produce 4 moles CO2 and 6 moles H2O

C2H6 is the limiting reactant. It will completely be consumed ( 0.668 moles).

O2 is in excess. There will react 7/2 * 0.668 = 2.338 moles

There will remain 2.97 - 2.338 = 0.632 moles O2

Since ethane is the limiting reactant. It will completely be consumed. There will remain 0 grams of ethane.

Which aqueous solution has the highest boiling point?a. 0.20 M NaClb. 0.10 M CaCl2c. 0.1 M Ga2(SO4)3d. 0.2 M C6H12O6
abruzzese [7]

Answer:

c. 0.1 M Ga₂(SO₄)₃

Explanation:

The boiling point increasing of a solvent due the addition of a solute follows the formula:

ΔT = K*m*i

<em>Where K is boiling point increasing constant (Depends of the solute), m is molality = molarity when solvent is water, and i is Van't Hoff factor.</em>

<em />

That means the option with the higher m*i will be the solution with the highest boiling point:

a. NaCl has i = 2 (NaCl dissociates in Na⁺ and Cl⁻ ions).

m* i = 0.20*2 = 0.4

b. CaCl₂; i = 3. 3 ions.

m*i= 0.10M * 3 = 0.3

c. Ga₂(SO₄)₃ dissolves in 5 ions. i = 5

m*i = 0.10M*55 = 0.5

d. C₆H₁₂O₆ has i = 1:

m*i = 0.2M*1 = 0.2

The solution with highest boiling point is:

<h3>c. 0.1 M Ga₂(SO₄)₃</h3>

What attractive force draws in surrounding electrons for chemical bonds?
Dmitrij [34]

The formation of chemical bonds occurs due to the attractive forces between oppositely charged ions (ionic bonds) or by sharing of electrons (covalent bonds).

An atom having tendency of attracting a shared pair of electrons towards itself and this chemical property is said to Electronegativity .

Thus, the attractive forces which draws in surrounding electrons for chemical bonds is electronegativity.

How many grams of NaCl are in 3.5 mol of NaCl? Also, how many moles of NaCl are in 150 g of NaCl?​
alexandr402 [8]

Answer:

204.5505 grams

2.5666 moles

Explanation:

For the first question, multiply 3.5 (# of moles) by 58.443 (g/mol for NaCl).

58.443 * 3.5

<em>I'll distribute 3.5 into 58.443.</em>

(3.5 * 50) + (3.5 * 8) + (3.5 * 0.4) + (3.5 * 0.04) + (3.5 * 0.003)

175 + 28 + 1.4 + 0.14 + 0.0105

203 + 1.4 + 0.14 + 0.0105

204.4 + 0.14 + 0.0105

204.54 + 0.0105

204.5505 grams

There are 204.5505 grams in 3.5 moles of NaCl.

For the second question, divide 150 (# of grams) by 58.443 (g/mol for NaCl). I'll convert both into fractions.

150/1 * 1000/58443

150000/58443

2.56660336 moles

2.5666 moles (rounded to 4 places to keep consistency with the first answer) are in 150 grams of NaCl.
