< (O %#3 Two bulbs are connected by a stopcock. The 9.00 L bulb contains nitric oxide (NO) at a pressure of 0.517 bar, and the 3.00 L bulb contains oxygen (O,) at a pressure of 0.775 bar. After the stopcock is opened, the gases mix and react to produce nitrogen dioxide ON 0, (CON) (3) ON7- (3)°0+ (3)ON 7 Considering that the volume remains unchanged during the experiment, how does the total pressure in the bulbs change if the reaction is allowed to go to completion? O The total pressure will increase. O The total pressure will remain constant. There is not enough information to determine how the total pressure will change. The total pressure will decrease.

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
