Condensation happens when molecules in a gas cool down. As the molecules lose heat, they lose energy and slow down. They move closer to other gas molecules. Finally these molecules collect together to form a liquid.

A single-replacement reaction replaces one element for another in a compound.

A double-replacement reaction exchanges the cations (or the anions) of two ionic compounds.

A precipitation reaction is a double-replacement reaction in which one product is a solid precipitate.

Solubility rules are used to predict whether some double-replacement reactions will occur.

is it multiple choice question??

Van der Waals forces are the interaction between the molecules and the atoms. It increases with an increase in the molecular size and the number of electrons. Thus, options B and C are correct.

Van der Waals forces are the weak forces of attraction and repulsion present between the atoms and the molecules of the compounds. They are also called London Dispersion Forces and dipole-dipole forces.

An increase in the number of electrons and size of the molecule increases the surface area and the electron cloud which in turn, increases the Van der Waals force.

The intermolecular force increases as in large atoms or molecules the valence are held loosely as they are far from the nucleus or the center of the atom.

Therefore, the size and the electron increase the Van der Waals force.

Answer:

lol where is your questions??

Answer:

the elements are listed in order of increasing atomic number. The atomic number is the number of protons in the nucleus of an atom.In a periodic table arranged in order of increasing atomic number, elements having similar chemical properties naturally line up in the same column.

The elements on the periodic table are arranged on the basis of highlighting similarities between elements. Thus, the correct option for this question is A.

The elements on the periodic table are basically arranged on the basis of increasing their atomic number. These atomic number is represented by the number of protons in the nucleus of an element.

According to the question, the elements possessing identical chemical properties are arranged in the same group. For example, group 17 is known as the halogen group. Among this group, the elements bear one electron short to fulfill their octet.

The whole periodic table comprises of 18 groups and 7 periods.

Therefore, the elements on the periodic table are arranged on the basis of highlighting similarities between elements. Thus, the correct option for this question is A.

Answer:

Yes, the investigations will reach similar conclusions about the reactivity of H2 and Cl2

Explanation:

1. The law of multiple proportions says that when elements form compounds, the proportions of the elements in those chemical compounds can be expressed in small whole number ratios.  This means that regardless of whether 1000 times more of the products are used, the reactivity of the products is established by the chemical reaction

2. The law of multiple proportions is an extension of the law of definite composition, which states that compounds will consist of defined ratios of elements.

3. A reaction with more reactants will need more care because more products are produced, which can be toxic

4. H2 and Cl2 reactivity does not depend on the quantities but the chemical properties of each compound
