A . well test explanation for a broad set of observations.
Answer: Option (a) is the correct answer.
Explanation:
Ionic salts are defined as the salts which tend to contain ionic bonds as there occurs transfer of electrons between its combining atoms.
So, when an ionic salt melts or it is dissolved in water then it will dissociate into its respective ions and as electricity is the flow of electrons or ions. Hence, this salt is then able to conduct electricity.
As covalent compounds are insoluble in water so, they do no dissociate into ions. Hence, they do not conduct electricity.
Similarly, metallic and network solids do not dissociate into ions either when melted or dissolved in water. Therefore, they also do not conduct electricity.
Thus, we can conclude that when a white crystalline salt conducts electricity when it is melted and when it dissolves in water then this bond is of ionic type.
Answer:
Both the C and the N can participate in reactions
Explanation:
The word ambident comes from two Latin words that mean "both teeth".
An ambident group can react at two different sites to form products.
For example, the cyano group has two major resonance structures (see below).
The hybrid has two different ends, each with a lone pair and a partial negative charge.
Thus, it can react to form CH₃CN by having the C attack, or CH₃NC by having the N attack.
Answer:her weight
Explanation:
weight varies from place to place (you weight differs on earth than is does the moon), her mass however always stays the same wherever she may be
Answer:
168°C is the melting point of your impure sample.
Explanation:
Melting point of pure camphor= T =179°C
Melting point of sample = = ?
Depression in freezing point =
Depression in freezing point is also given by formula:
= The freezing point depression constant
m = molality of the sample = 0.275 mol/kg
i = van't Hoff factor
We have: = 40°C kg/mol
i = 1 ( non electrolyte)
168°C is the melting point of your impure sample.
