4. Juan tiene un cilindro de 40 libras herméticamente cerrado con gas propano y lo conecta mediante una válvula a otro cilindro

de 100 libras completamente vacío. Si Juan abre la válvula del cilindro de 40 dejando pasar el gas al de 100. responda
¿Qué cantidad de gas propano le haría falta al cilindro de 100 y por qué?

Answer:

Ver explicacion

Explanation:

Cuando el cilindro de 40 libras está conectado al cilindro de 100 libras, generamos una presión que continúa hasta que los dos cilindros alcanzan la misma presión de gas en equilibrio. Recuerde que el cilindro de 100 libras estaba inicialmente vacío. Esto significa que su presión inicial es 0. El cilindro de 40 libras ya estaba lleno, por lo que dividimos esta cantidad en dos para tener en cuenta su distribución entre los dos cilindros.

Ahora tenemos 20 libras de gas propano presentes en cada cilindro. La implicación de esto es que, en el cilindro de 100 libras, necesitamos 80 libras adicionales para completar las 100 libras.

Molecular iodine, I2 (g), dissociates into iodine atoms at 545K with a first order rate constant of 0.344 1/s. If you start with
Dennis_Churaev [7]

Answer:

0.00915 M of I_2 remain after 5.16 seconds.

Explanation:

Using integrated rate law for first order kinetics as:

[A_t]=[A_0]e^{-kt}

Where,  

[A_t] is the concentration at time t

[A_0] is the initial concentration

Given that:

The rate constant, k = 0.344 s⁻¹

Initial concentration [A_0] = 0.054 M

Final concentration [A_t] = ? M

Time = 5.16 s

Applying in the above equation, we get that:-

[A_t]=0.054e^{-0.344\times 5.16}\ M=\frac{1\times \:0.054}{e^{1.77504}}\ M=0.00915\ M

<u>0.00915 M of I_2 remain after 5.16 seconds.</u>

Thorium-234 has a half-life of 24.1 days. How much of a 100-g sample of thorium-234 will be unchanged after 48.2 days?
oee [108]
Half-life means that the matter degrades by 50% at each interval. 48.2 days is 2 intervals.

So, it would go down by 50% in the first interval, making it 50g. Then it would go down by another 50% from there, making the final amount of undecayed thorium-234 25g.

Energy level of diagram​
nlexa [21]

Answer:

<em>The energy level diagram is used to represent the energy states available in each atom. When an electron is in an energy state, it emits nor absorbs radiation. A photon is emitted or absorbed when an electron transitions from one energy state to another.</em>
