Find the % composition for each element in Zn(CIO3)2

bezimeni [28]

Zn = 28.15%

Cl = 30.53%

O = 41.32%

<h3>Further explanation</h3>

Given

Zn(CIO3)2 compound

Required

The % composition

Solution

Ar Zn = 65.38

Ar Cl = 35,453

Ar O = 15,999

MW Zn(CIO3)2 = 232.3

Zn = 65,38/232.3 x 100% = 28.15%

Cl = (2 x 35.453) / 232.3 x 100% = 30.53%

O = (6 x 15.999) / 232.3 x 100% = 41.32%

Some nitrogen for use in synthesizing ammonia is heated slowly, maintaining the external pressure close to the internal pressure

Answer: The work done for the given process is -2188.7 J

Explanation:

To calculate the amount of work done for an isothermal process is given by the equation:

$W=-P\Delta V=-P(V_2-V_1)$

W = amount of work done = ?

P = pressure = 50.0 atm

$V_1$ = initial volume = 542 L

$V_2$ = final volume = 974 L

Putting values in above equation, we get:

$W=-50.0atm\times (974-542)L=-21600L.atm$

To convert this into joules, we use the conversion factor:

$1L.atm=101.33J$

So, $-21600L.atm=-21600\times 101.33=-2188728J=-2188.7kJ$

The negative sign indicates the system is doing work.

Hence, the work done for the given process is -2188.7 J
