A tank has a volume of 0.1 m3 and is filled with He gas at a pressure of 5 x 106 Pa. A second tank has a volume of 0.15 m' and i
GarryVolchara [31]

Answer:

P=5.6*10^{6} Pa

Explanation:

Consider that, as the system is adiabatic, U_{1}= U_{2} where U1 and U2 are the internal energies before the process and after that respectively.

Consider that: U=H-PV, and that the internal energy of the first state is the sum of the internal energy of each tank.

So, H_{1}-P_{1}V_{1}=H_{2}-P_{2}V_{2}\\H_{1}^{A} -P_{1}^{A}V_{1}^{A}+H_{1}^{B} -P_{1}^{B}V_{1}^{B}=H_{2}-P_{2}V_{2}

Where A y B are the tanks. The enthalpy for an ideal gas is only function of the temperature, as the internal energy is too; so it is possible to assume: H_{1}=H_{2}\\H_{1}^{A}+H_{1}^{B} =H_{2}

So, P_{1}^{A}V_{1}^{A}+P_{1}^{B}V_{1}^{B}=P_{2}V_{2}

Isolating P_{2},

P_{2}=\frac{P_{1}^{A}V_{1}^{A}+P_{1}^{B}V_{1}^{B}}{V_{2}}

V_{2}=V_{1}^{A}+V_{1}^{B}=0.25m^{3}

So,

P_{2}=\frac{5000000*0.1+6000000*0.15}{0.25}=5600000Pa=5.6*10^{6} Pa

How many moles of nitrogen are in 2.0×10−2mole of quinine?
galben [10]

Answer: 4 x 10 ∧-2  moles of nitrogen.

Explanation:

The chemical formular for quinine is ; C20 H24 N2 O2

As can be seen from the chemical formular;

1 mole of quinine contains 2 moles of Nitrogen

Thus; 2.0 x 10 ∧-2 moles of quinine would contain

         2.0 x 10 ∧-2 x 2 = 4 x 10 ∧-2  moles of nitrogen.

 Therefore 4 x 10 ∧-2  moles of nitrogen are in 2.0×10−2mole of quinine
