The correct answer is option B. The most dense phase of matter is the solid phase and the least dense are gases. However, there is an exception. Water is the exception. Solid water or ice is less dense than the liquid phase therefore it floats on liquid water.

Answer:

b. Solid

Explanation:

Density is a measure of how much mass, essentially particles are packed in a unit volume of a substance. So the more packed mass is in a unit volume, the higher the density of a substance. It follows then that a solid, the substance with the most packed arrangement of particles is normally the one with the highest density.

Which of these statements is/are true? Rewrite each false statement to make it true.

Lelechka [254]

<h3>Answer:</h3>

TRUE- The surface tension of CH3Br is greater than the surface tension of CH3Cl.

FALSE-Water forms spherical drops on wax because the surface tension of water is greater than the adhesive forces between wax and water.

<h3>Explanation:</h3>

The statement that, the surface tension of CH3Br is greater than the surface tension of CH3Cl is true.
This is because of the fact that CH₃Br has more molar mass compared to CH₃Cl. Additionally, CH₃Br has greater dispersion forces and is more polarizable thus having greater surface tension compared to CH₃Cl.
The statement that "Water forms spherical drops on wax because the surface tension of water is greater than the adhesive forces between wax and water" is FALSE.
We would correct it by saying, Water forms spherical drops on wax because the cohesive force of water is greater than the adhesive forces between wax and water.
Cohesive forces are forces of attraction between molecules or particles of the same type while adhesive forces is a force of attraction between molecules of different type.

Wine goes bad soon after opening because the ethanol ch3ch2oh in it reacts with oxygen gas o2 from the air to form water h2o and

lilavasa [31]

The balanced chemical equation of the reaction described above is,

C2H6O + O2 --> H2O + C2H4O2

If we have 3.84 g of oxygen, we divide by its molar mass.

n = (3.54 g Oxygen gas) x (1 mole O2/ 32 g O2)
n = 0.11 moles O2

Using ratio and proportion,

number of moles of ethanol = (0.11 moles O2) x (1 mole C2H6)
= 0.11 moles C2H6

Then, we multiply the calculated value to its molar mass, 46 grams /mol.
mass of ethanol = (0.11 mol) x (46 grams / mol)
= <em>5.06 grams</em>
