Conduction because it transfers thermal energy
Mandarinka [93]2 years ago
3 0

Answer:Conduction occurs when energy is passed between objects. The transfer of thermal energy is called heat. Particles of matter are in constant motion.

Which of the following best helps to explain why the electron affinity of Br has a greater magnitude than that of I?
tankabanditka [31]

The reason why  Br has a greater magnitude of electron affinity than that of I is that there is a greater attraction between an added electron and the nucleus in Br than in I.

In the periodic table, there are trends that increase down the group and across the period. Electron affinity is a trend that increases across the period but decreases down the group.

Recall that the ability of an atom to accept an electron depends on the size of the atom. The smaller the atom, the greater the attraction between an added electron and the nucleus.

Since Br is smaller than I, there is a greater attraction between an added electron and the nucleus in Br than in I which explains why Br has a greater magnitude of electron affinity than  I.

(b) Briefly explain how the presence of charged ions in ionic solids such as NaCl(s) helps to explain why NaCl(s) is a soluble i
bonufazy [111]

Answer:

-The stronger electrostatic forces of attraction between the oppositely charged ions causes the Sodium chloride to break apart until it completely dissolves in the water.

Explanation:

-Sodium Chloride has positively charged sodium ions, Na^+ and negatively charged chloride ions, Cl^-.

-Water on the other hand has positively charged Hydrogen ions,H^+ and negatively charged Oxygen ions, O^{2-} due to the difference in electroneganivity.

-When dissolved in water, the positively charged sodium ions will attract the partially negatively charged oxygen ions. The negatively charged chloride ions will be attracted to the positively charged hydrogen ions in the reaction as below:

NaCl+H_2O->NaOH+HCL\\\\Na^++Cl^-+H_2O->Na^++(OH)^-+H^++Cl^-
