The answer is (4) metallic, because the valence electrons are mobile
marishachu [46]3 years ago
6 0

Answer;

-4. metallic, because the valance electrons are mobile

Explanation;

-Electrical conductivity in metals is a result of the movement of electrically charged particles.The atoms of metal elements are characterized by the presence of valence electrons (electrons in the outer shell of an atom) that are free to move about.

-Therefore; Metallic elements such as sodium and potassium conducts electricity in solid form due to the presence of delocalized valence electrons. These electrons can move freely within the structure of a metal when an electric current is applied.

The latent heat of melting is 80 calories for 1 gram of ice. if 1 gram of ice absorbs 60 calories what do i get?
Eva8 [605]
Latent heat of melting is the energy that a solid absorbs to change its phase as its liquid. During this process, since all energy is used to change the phase, the temperature is constant.

Here the latent energy of melting for 1 g of ice is 80 calories and that 1 g of ice only absorbed 60 calories. hence the phase is not changed because it requires more 20 calories to melt.

Hence 1 g of ice remains as its solid phase (ice).

During an experiment, it is observed that iron powder sinks in water and sulfur powder floats in water. What will most likely be
lutik1710 [3]

Sulfur will float, and iron will sink because each will retain its properties.

“Iron will float, and sulfur will sink because each will lose its properties” is <em>incorrect</em>. A substance will lose its properties only if it reacts to form a new substance.

“Both will float because they are physically mixed” is <em>incorrect</em>. The substances in a mixture retain their properties.

“Both will float because they react chemically” is <em>incorrect</em>. Iron and sulfur do not react at room temperature. Even if they did, the iron sulfide would sink.
