Ans: C) and E)
A solid solution is essentially a multicomponent system which is composed of a mixture of two or more elements sharing the same crystal lattice. Alloys are solid solutions.
The requirement for one type of atom to substitute for another in a solid solution are two fold
1) The atom must be similar in size
2) The substituting atom must be from the same group.

The temperature of the balloon will decrease.
The gas atoms will strike the sides of the balloon more often.
The gas inside the balloon will change into a liquid.
Answers
Answer: The gas atoms will strike the sides of the balloon more often.
Explanation:
Kinetic energy is the energy possessed by an object by virtue of its motion.
Average kinetic energy is defined as the average of the kinetic energies of all the particles present in a system. It is determined by the equation:
K= kinetic energy
R= gas constant
T= temperature
From above, it is visible that kinetic energy is directly related to the temperature of the system.
So if average kinetic energy of the system increases , the speed of the molecules will be more and hence the gas atoms will strike the sides of the balloon more often.

Answer:
Cl is more likely to than Na
Explanation:
The question asks for the element more take up an electron from the other
The ability of an atom to take take or give electrons in a chemical reaction, depends on its electron affinity and ionization energy, respectively
Chlorine, Cl, has the highest electron affinity in the periodic table which makes it attract electrons more towards itself
Sodium, Na, has a low ionization energy (about 2/5 of that of chlorine) than chlorine, Cl, making sodium more readily able to give its valence electron in a reaction
Therefore, Cl is more likely to take up an outer electron from Na.

The bonds found between water molecules are called:
Hydrogen bonds
which contribute to water having a high number of Van Der Waals forces.
Explanation:
A hydrogen bond is an electromagnetic attraction within polar molecules in which hydrogen is joined to a larger atom, such as oxygen or nitrogen. This is not a dividing of electrons, as in a covalent bond. Preferably, this is an attraction among the positive and negative poles of charged atoms.
Answer:
Hydrogen bonds
