Answer:
(a)
(b) The particles of the formed barium sulfate remain suspended in the aqueous media forming a colloid.
Explanation:
Hello,
In this case, when solutions of barium chloride and sodium sulfate are mixed, the following chemical reaction is carried out:
Thus, we can notice that the product barium sulfate remains solid since its solubility in aqueous media is very low, for that reason at the beginning the solution becomes cloudy as its particles remain suspended in the water forming a colloid. Nevertheless, after some days, the suspended particles get precipitated by the effect of the gravity, therefore, we observe the solid on the bottom of the beaker.
Regards.
Answer:
0.229 cm³.
Explanation:
The following data were obtained from the question:
Volume (in in³) = 0.014 in³
Volume (in cm³) =?
1 in = 2.54 cm
Next, we shall determine a conversion scale to convert from in³ to cm³. This can be obtained as follow:
1 in = 2.54 cm
Therefore,
1 in³ = 2.54³ cm³
1 in³ = 16.387 cm³
Finally, we shall convert 0.014 in³ to cm³. This can be obtained as follow:
1 in³ = 16.387 cm³
Therefore,
0.014 in³ = 0.014 in³ × 16.387 cm³ / 1 in³
0.014 in³ = 0.229 cm³
Thus, 0.014 in³ is equivalent to 0.229 cm³.
Answer:
Explanation:
In this case, we must analyze the structure for each molecule. In the case of , we have a bond with a chlorine atom. Chlorine has a high electronegativity, therefore the C-Cl bond has a relatively large dipole moment since we have a high electronegativity difference.
In the molecule, we have two bonds of this type, therefore we will have two high dipole moments. Thus, the net dipole moment for this second molecule should be higher.
This statement can be confirmed if we look at the <u>dielectric constant</u>, this value is an indicator of the polarity of a molecule. If we have a high dielectric constant there will be more polarity and therefore a higher net dipole moment.

In the following choices, all of the above are an end product of fractional distillation except for one. The ones that are the end product of fractional distillation are, asphalt, heating oil and kerosene. Crude petroleum is not an end product of fractional distillation, so the correct answer is letter A.
The answer is complex carbohydrates.
Hope that helps! :)
