Carbon Dioxide in a 34 L container at a pressure of 387 mm Hg is transferred to a container with a pressure of 274 mm Hg. What i
AVprozaik [17]

Answer:

V2= 0.0796m3

Explanation:

We have that for a real gas the following relation is fulfilled:

PV / T = constant

To use this formula I need to pass the pressure of mmHg to KPa and the volume of L to m3, knowing that

 1Kpa = 7.50062mmHg

1L = 0.001m3

So i can say

P1V1/T1 =P2V2/T2

So

V2= P1V1T2/P2T1

V2= 51.60KPa*0.034m3*350k/36.53KPa*211k

finally

V2= 0.0796m3

How much heat (in kilojoules) is evolved or absorbed in the reaction of 1.90g of Na with H2O ?
irina1246 [14]
The heat of the reaction is an extensive property: it is proportional to the quantity of the quantity that reacts.

The change in enthalpy is a measured of the heat evolved of absorbed.

When the heat is released, the change in enthalpy is negative.

The reaction of 2 moles of Na develops 368.4 kj of energy.

Calculate the number of moles of Na in 1.90 g to find the heat released when this quantity reacts.

Atomic mass of Na: 23 g/mol

#mol Na = 1.90 g / 23 g/mol = 0.0826 mol

Do the ratios: [368.4 kj/2mol ] * 0.0826 mol = 15.21 kj.

Then the answer is that 15.21 kj of heat is released (evolved)
