An electrolyte is a substance that will conduct electricity when dissolved in water. a substance that conducts electricity well is a strong electrolyte. a substance that conducts electricity poorly is a weak electrolyte. in contrast, a substance that does not conduct electricity when dissolved in water is a nonelectrolyte. watch the video about the electrolytic properties of sodium chloride, nacl, and sugar. watch the animation, then check off the samples that will conduct electricity. check all that apply. a. solid sugarb. solid naclc. nacl solutiond. sugar solution

Explanation:

As it is known that an electrolyte in which solute particles completely dissociate into ions in a solvent is known as a strong electrolyte.

For example, NaCl is an ionic compound and when it is added to water then NaCl will completely dissociate into sodium and chloride ions.

Therefore, this solution will be able to conduct electricity. Whereas in solid NaCl there will be no presence of ions. As a result, solid NaCl is not able to conduct electricity.  

But when sugar is added to water then it will not dissociate into ions. Hence, a sugar solution is not able to conduct electricity.

Thus, we can conclude that NaCl solution will be able to conduct electricity.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
