Una determinada cantidad de neón ocupa 0,5 litros (L) a 200ºC. Calcular el volumen que ocuparía a 0ºC si la presión se mantiene

Basile [38]

Answer:

$V_2=0.87L$

Explanation:

¡Hola!

En este caso, al considerar la información dada, inferimos que este problem se resuelve aplicando la ley de Charles, dado que tenemos una relación entre el volume y la temperatura:

$\frac{V_2}{T_2}=\frac{V_1}{T_1}$

Así, despejamos V2 (volumen final) y obtenemos:

$V_2=\frac{V_1T_2}{T_1}\\\\V_2=\frac{0.5L*473.15K}{273.15K}\\\\V_2=0.87L$

Saludos!

NaCl + H2O → NaOH + Cl2 + H2 Balance the equation. Choose "blank" if no coefficient is needed. NaCl + H2O → NaOH + Cl2 ++ H2

alexgriva [62]

The balanced equation is:

2NaCl + 2 H2o → 2 NaOH + Cl2 + H2

1- we put 2 NaCl to balance Cl2 on the other side.
2- we put 2 NaOH to balance Na
3- We put 2 H2O to balance H & O on the to sides
