Since obliquity is the angle between the axis of rotation and the direction perpendicular to the orbital plane, it changes as the orbital plane changes due to the influence of other planets. But the axis of rotation can also move (axial precession), due to torque exerted by the sun on a planet's equatorial bulge.

<u>Answer:</u> The total pressure of the container will be 2.00 atm
<u>Explanation:</u>
We are given:
Initial moles of phosphorus pentachloride = 1.00 atm
For the given chemical reaction:
By Stoichiometry of the reaction:
1 mole of 
produces 1 mole of 
and 1 mole of chlorine gas
So, 1.00 atm of will also produce 1.00 atm of and 1.00 atm of chlorine gas when the reaction goes to completion.
Total pressure of the container when the reaction goes to completion = 1.00 + 1.00 = 2.00 atm
Hence, the total pressure of the container will be 2.00 atm
The correct answer is option 4 and 5.
The electron domain geometry for an ammonia molecule, NH₃ has tetrahedral electron domain geometry. In NH₃ there are three bond pair electrons and one lone pair electron. Therefore, NH₃ has four electron pairs which are distributed in a tetrahedral shape.
The molecular geometry for an ammonia molecule, NH₃ is trigonal-pyramidal molecular geometry. Ammonia has one lone pair of electron and three bond pairs of electrons thus the resulting molecular geometry is trigonal-pyramidal.
