Is gasoline a compound or a mixture? compound mixture

Chemistry
2 answers:
Kobotan [32]3 years ago
5 0

Answer:

It is a mixture.

Explanation:

A compound is a pure substance which cannot be separated into its constituent by physical methods.

A mixture is a substance which can be separated into its constituent by physical methods.

Gasoline consists of different organic liquids.

These organic liquids can be separated by physical means like fractional distillation.

Thus gasoline will be a mixture. More specifically it is a homogeneous mixture.

A liquid mixture contains 1 kg of water, 1.9 lb of ethanol, and 4.6 lb of methyl acetate. What is the weight fraction of ethanol
slamgirl [31]

<u>Answer:</u> The weight fraction of ethanol in the mixture is

<u>Explanation:</u>

We are given:

Mass of water = 1 kg = 2.205 lb   (Conversion factor:  1 kg = 2.205 lb)

Mass of ethanol = 1.9 lb

Mass of ethyl acetate = 4.6 lb

Mass of mixture = [2.205 + 1.9 + 4.6] = 8.705 lb

To calculate the percentage composition of ethanol in mixture, we use the equation:

\%\text{ composition of ethanol}=\frac{\text{Mass of ethanol}}{\text{Mass of mixture}}\times 100

Mass of mixture = 8.705 lb

Mass of ethanol = 1.9 lb

Putting values in above equation, we get:

\%\text{ composition of ethanol}=\frac{1.9lb}{8.705lb}\times 100=21.8\%

Hence, the weight fraction of ethanol in the mixture is 21.8 %

A spring requires a force of 25 n to produce an extension of 2 cm in it. what is the work done in further extending it by 3 cm
Sonbull [250]
The force of a spring can be calculated by the expression:

F = kx  where k is a constant and x is the distance.

From the problem statement, we can solve the value of k from the initial conditions given as F = 25 N and x = 2 cm.

25 = k (0.02)
k = 1250

We use the work formula which is force times the distance resulting to the expression:

W = (1/2)(kx^2)
W = (1/2)(1250)(0.03^2)
W = 0.5625 J
