Question

15 cm cube of liquid X and 20 cm cube of liquid by are mixed at 20 degree centigrade and the volume of total volume of solution was measured to be 35.1 then collect reactionaries

Answer 1

Answer:

the periodic table as periodic table element is a tabular display of chemical element which are arranged by atomic number electron configuration and requiring chemical property structure of the table shows periodic table

Answer 2

Answer: ΔHmix <0, solution shows -ve deviation.

Explanation: As A = $V_{A}=15 cm^{3}$

Now B=$V_{B}=20 cm^{3}$

So now by $V_{A} +V_{B}=15+20=35 < 35.1 cm^{2}$,

As ΔVmix>0⇒+ve

As A-A, B-B > A-B   As it is the positive deviation,

As we know, the negative deviation law, ΔHmax=-ve

Hence, the correct answer will be ΔHmix <0,
