Natalija [7]

Answer:

Mass of the water is equal to the mass of ice

Explanation:

When ice melts, the mass remains the same even though its volume decreases leading to a decrease in density of water.

The mass remains the same because according to the law of conservation of mass, mass can neither be created nor destroyed. Since mass is neither created nor destroyed in the process of melting, the mass of water must remain the same.

What properties of water would help water travel up the leaf?
Anna [14]
The high surface tension of water pulls the concavity outwards, generating enough force to lift water from the roots to the leaves of plants. Thus, Cohesion, along with adhesion and surface tension creates a capillary action that keeps water molecules interacting and moving through the plants out to the leaf cells.

The melting points of the two constitutional isomers are as follows: ortho-hydroxy acetophenone: 4-6 °C; para-hydroxy acetopheno
love history [14]

Answer:

ortho-hydroxy acetophenone form intramolecular hydrogen bonding. On the other hand, para-hydroxy acetophenone forms intermolecular hydrogen bonding.

Explanation:

Hydrogen bonding:-

  • Hydrogen bonding is a special type of the dipole-dipole interaction and it occurs between hydrogen atom that is bonded to highly electronegative atom which is either fluorine, oxygen or nitrogen atom.
  • Partially positive end of the hydrogen atom is attracted to partially negative end of these atoms which is present in another molecule. It is strong force of attraction between the molecules.

The bonding can be intramolecular and intermolecular. ortho-hydroxy acetophenone can form intramolecular hydrogen bonding which means that hydrogen bonding exist within the same molecule. On the other hand, para-hydroxy acetophenone forms intermolecular hydrogen bonding in which the bonding is in between the different molecules.<u> Hence, more amount of energy is required to melt these molecules in case of para-hydroxy acetophenone. </u>

<span>Which of the following gases would be most likely to experience ideal behavior at high pressures? 
a. F2 
b. Ne 
c. C2H6 

Yes. The answer is (b) Ne (Neon). This is because monoatomic gases such as neon do not experience </span><span>intermolecular attractions and thus most likely to be close to ideal gases behavior. Not only that, Neon is a noble gas and is unreactive. </span>
