The state of matter with a specific volume but no definite shape is the _____ state.

bagirrra123 [75]

The state of matter with a specific volume but no definite shape is the Liquid state.

Explanation:

There are three states of matter according to chemical science: Solid, Liquid and Gas. There is not much space in among the molecules. The particles in a liquid are free to float, so while a liquid has a certain volume it has no definite form. Liquids are composed of atoms or molecules bound by inter molecular bonds.

Most of the liquids resist compression while some do not, unlike a gas, a liquid will not spread to fill any container room and will retain a fairly constant density. A characteristic liquid state property is surface tension that results to wetting phenomena. Water is perhaps the most frequent substance on Earth.

Predict the aldol product when the following ketone undergoes self-condensation in the presence of NaOH. Do not show the dehydra

Anit [1.1K]

Answer:

β-hydroxyaldehyde (an aldol) namely 3-Hydroxy butanal.

Explanation:

When acetaldehyde is treated with dil.NaOH it undergoes self condensation as it contains alpha-hydrogen atom in its compound forming β-hydroxyaldehyde (an aldol) namely 3-Hydroxy butanal. This compound upon further heating will eliminate a molecule of water forming aldol condensation product namely Crotonaldehyde Or But-2-en-al. see the diagram attached.

nexus9112 [7]

Answer is: The solution has now become a good conductor of electricity.

Hydrochloric acid (HCl) dissociate on positive ions or cations of hydogen (H⁺) and negative ions or anions of chlorine (Cl⁻) accordinf to balanced chemical reaction:

HCl(aq) → H⁺(aq) + Cl⁻(aq).

When there are free cations and ions, water solution can conduct electricity.
