I guess it is gases
I think , coz it has its own shape
Moves randomly
Answer:
Explanation:
Due to Coulomb´s law electric force can be described by the formula , where K is the Coulomb´s constant (), = Charge 1 (Na+ in this case), is the charge 2 (Cl-) and r is the distance between both charges.
Work made by a force is W=F.d and total work produced is the change in energy between final and initial state. this is .
so we have
Given that ri= 1.1nm= and rf= infinite distance
Answer: It is preferable to add excess bromobenzene instead of excess acetophenone because the reaction is exothermic and the addition of too much acetophenone causes the temperature to rise rapidly which may lead to an explosion.
Explanation:
The preparation of 1,1- diphenyl ethanol by reaction between bromobenzene and acetophenone is known as Grignard reaction.
The mechanism of this reaction is given in the adjoining image.
In this reaction, acetophenone is added slowly and in small amounts because this reaction is exothermic.
If a large quantity of acetophenone is added simultaneously, it can lead to the temperature rising too much in a short duration of time and may cause an explosion which may injure the person performing this reaction.
Also, too much acetophenone becomes an impurity which further hampers the reaction.
Therefore, it is preferable to add excess bromobenzene instead of excess acetophenone.

Answer:
CH3OH, NaBr, CaCl2, Cr(NO3)3
Based on disorderliness, the ionization strength gives the entropy.
CH3OH - Does not ionize, it's a solvent
NaBr- Ionizes intwo two ions
CaCl2- Ionizes to three ions 1Ca and 2 Cl ions
Cr(NO3)3- Ionizes to four ions
