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

Explanation:

...OK hope it helps .......

Answer 2

Answer:

The correct reaction is Δ$H_{mix}$ > 0, the solution shows a positive deviation.

Explanation:

Given:

Volume of liquid X ($V_X$) = 15 cubic cm

Volume of liquid Y ($V_Y$) = 20 cubic cm

To find:

Correct reaction.

Solution:

$V_X=15 cm^3$ and $V_Y=20cm^3$

Therefore, the total volume of the solution is

$V=V_X+V_Y$

$V=15+20$

$V=35cm^3$

The measured volume of the solution was 35.1 cubic cm.

So, V < 35.1. Therefore, ΔV = 0.1

Since ΔV > 0, i.e., ΔV is positive, it will show a positive deviation.

Therefore, Δ$H_{mix}$ > 0, the solution shows a positive deviation.
