Partial pressure is the pressure that is exerted by individual gases.
Partial pressure is calculated as the product of total pressure by the mole fraction of the corresponding gas.
pressures exerted by gases are in three different units, therefore we can convert them all into a common unit - torr
1 - 0.845 atm - 0.854 atm x 760 Torr/atm = 642 torr
2 - 120 torr
3 - 210 mmHg - 1 mmhg is almost equivalent to 1 torr - therefore its 210 torr
total pressure - 642 + 120 + 210 = 972 torr
answer is 972 torr
Answer:
The electron configuration of magnesium is [Ne] 3s 2. It is an s block element, and it occurs as a solid at standard temperature and pressure. It is a shiny grey metal. The melting point and boiling points are 650 °C and 1091 °C respectively. The most common and stable oxidation state is +2, but it can form +1 oxidation state as well. In writing the electron configuration for Magnesium the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for magnesium go in the 2s orbital. The nex six electrons will go in the 2p orbital. The p orbital can hold up to six electrons. We'll put six in the 2p orbital and then put the remaining two electrons in the 3s. Therefore the Magnesium electron configuration will be 1s22s22p63s2.

Answer:
In this process The more dense gases are collected in a gas jar. Carbon dioxide, Nitrogen dioxide are collected by this way. Air is displaced upward thus, this process is known as upward delivery
