Hexane and hexene are hydrocarbon compounds from different homologous series. the combustion of these two compounds produce diff

AURORKA [14]

Answer:

Percentage of carbon of alkene is higher compared to the alkane that has the same number of carbon per molecule. Because of this, combustion of alkene will produce more sooty flame compared to their corresponding alkane and because Alkenes have a higher percentage of carbon compared to their corresponding alkane.

Explanation:

Relative atomic mass : C= 12 and H=1

Percentage of Carbon Hexane (C6H14)

Percentage of Carbon = 83.7 percent

6(12) x 6(12) +14(1) x 100 percent= 83.7 percent

Percentage of Carbon Hexene = 85.7 percent

A throat spray is 1.40% by mass Phenol, C6H5OH in water. If the solution has a density of 0.9956 g/ml, calculate the molarity of

myrzilka [38]

<u>Answer:</u> The molarity of solution is 1.08 M

<u>Explanation:</u>

We are given:

(m/m) of phenol = 1.40 %

This means that 1.40 g of phenol is present in 100 g of solution.

To calculate volume of solution, we use the equation:

$\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}$

Density of solution = 0.9956 g/mL

Mass of solution = 100 g

Putting values in above equation, we get:

$0.9956g/mL=\frac{100g}{\text{Volume of solution}}\\\\\text{Volume of solution}=100.442mL$

To calculate the molarity of solution, we use the equation:

$\text{Molarity of the solution}=\frac{\text{Mass of solute}\times 1000}{\text{Molar mass of solute}\times \text{Volume of solution (in mL)}}$

We are given:

Mass of solute (phenol) = 1.40 g

Molar mass of phenol = 94.11 g/mol

Volume of solution = 100.442 mL

Putting values in above equation, we get:

$\text{Molarity of solution}=\frac{1.40g\times 1000}{94.11g/mol\times 100.442mL}\\\\\text{Molarity of solution}=0.15M$

Hence, the molarity of solution is 0.15 M

Select the objects that hold the same amount of liquid as a 160−fluid-ounce jug. Select all that apply. A four 1−quart bottles B

Finger [1]

B, D and E

Explanation:

conversion factors

1c = 8oz

1pt = 2c

1qt = 2pt

For A and B

ounces to cup = 160/8 = 20c

cup to pints = 20c / 2c = 10pt

pint to quarts = 10pt/2pt = 5qt

B applies as four 1-quart and two 1-pt = 5 1-quart

Considering C

4 8oz = 32oz

160-32 = 128oz /8 = 16c/2 = 8pints C does not apply

considering D

8 * 8 = 64oz

160 - 64 = 96oz/8 = 12c/2 = 6pt/2 = 3qt

So D applies

E applies
