Answer:

Redox reactions are involved in the extraction of metals from their ores, eg extracting iron by reduction within the blast furnace. Transition metals have high melting points and densities, form coloured compounds and act as catalysts

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!
