A steel cylinder has a pressure of 550 torr at 177 degrees Celsius. What will be the pressure if the temperature is decreased by

Schach [20]

Answer:

$P_2=507.7torr$

Explanation:

Hello there!

In this case, when we have a gas that is undergoing a change in both pressure and temperature, we utilize the Gay-Lussac's equation as shown below:

$\frac{T_2}{P_2}=\frac{T_1}{P_1}$

Thus, since we are given the initial pressure and temperature and the final temperature, we can compute the final pressure as shown below:

$P_2=\frac{P_1}{T_1}*T_2$

So we plug in, by making sure the temperatures are in kelvins, to obtain:

$P_2=\frac{550torr}{(117+273)K}*(87+273)K\\\\P_2=507.7torr$

Best regards!

Calculate the number of atoms in exactly 3.5 moles of naturally occurring calcium.

trapecia [35]

2.11x10^24 Ca atoms

In order to find the amount of atoms we must use Avogadro’s number, 6.022 x 10^23

Since we have moles, 3.5 the equation would look like this

3.5 moles Ca x 6.022x10^23/1 = 2.1077 x 10^24, which we round to 2.11 x 10^24 atoms of Ca

A partir de lo propuesto por Bohr en 1913, que postulado es correcto:

TEA [102]

Answer:

Primer postulado:

Así Bohr asumió que el átomo de hidrógeno puede existir solo en ciertos estados discretos, los cuales son denominados estados estacionarios del átomo. En el átomo no hay emisión de radiación electromagnética mientras el electrón no cambia de órbita.
