Solutions of benzene, hexane and hexene can all be separated based on differences in boiling point.

A fail-proof method of identifying compounds is by the use of properties such as boiling point for liquids. Since Hexane, hexene and benzene are all liquids, the liquids can all be subjected to heating and the boiling points of the solutions are observed.

Recall that the boiling points of pure chemical substances have been documented in literature, the boiling points obtained for each sample can be compared with the boiling points in literature and the different solutions can be correctly identified:

Answer:

Solubility

Explanation:

Solubility units that incorporate units of solution include grams of solute per 100 grams of solution or grams of solute per liter of solution. Another way to express solubility is in moles of solute per liter of solution; this ratio is called "molarity."

In a certain chemical reaction Compound A combines with Compound B to produce Compound C (and no other products). Measurements w

Karo-lina-s [1.5K]

Answer:

Theoretical yield of C = 7.9 g

Actual amount of C isolated = 5.0 g

Explanation:

Given that in the reaction, Compound A combines with Compound B t o produce Compound C and no other products, the reaction is a combination reaction. The equation of the reaction is given below:

A + B ---> C

Part A:

From the measurement of the masses of A and B present before and after the reaction, the following values were obtained:

Initial mass of A = 4.0 g

Final mass of A = 0.0 g

Mass of A used up + 4.0 - 0.0 = 4.0 g

Initial mass of B = 9.0 g

Final mass of B = 5.1 g

Mass of B used up = 9.0 - 5.1 = 3.9 g

According to the law of conservation of mass, matter can neither be created nor destroyed but can change from one form to another. Therefore, theoretical yield of C equal the sum of the masses of A and B used up.

Theoretical yield of C = 4.0 + 3.9 = 7.9 g

Part B:

Given that the percent yield is 63.0 % = 0.63

Actual amount of C isolated = 0.63 * 7.9 = 5.0 g

What is the molarity of a NaOH solution if 28.2 mL of a 0.355 M H2SO4 solution is required to neutralize a 25.0-mL sample of the

Anni [7]

Answer:

A) 0.801

Explanation:

The reaction that takes place is:

2NaOH + H₂SO₄ → Na₂SO₄ + 2H₂O

First we calculate the H₂SO₄ moles that reacted:

0.355 M * 28.2 mL = 10.011 mmol H₂SO₄

Now we convert H₂SO₄ moles to NaOH moles:

10.011 mmol H₂SO₄ * $\frac{2mmolNaOH}{1mmolH_2SO_4}$ = 20.022 mmol NaOH

Finally we calculate the molarity of the NaOH solution:

20.022 mmol NaOH / 25.0 mL = 0.801 M

So the answer is option A.
