Answer: Le Chatleir Principle
Explanation: The answer of this question can be easily explanied through the Le Chatleir Principle which states that In order to maintain the equilibrium of the reaction, the stress applied to that particular direction will move the equilibrium to the opposite direction in which the stress has been applied.
The given reaction is -
If the amount of the oxygen is reduced to half and is being doubled, then the reaction will move in froward direction that is a rightward shift. Same situation will arise in option c and d.
If the amount of nitrogen monoxide is reduced to half or being doubled, the reaction will move towards backward direction that is a leftward reaction.
Answer:
Ideal Gas Law ( PV = nRT)
Explanation:
Using the Ideal Gas Law, we have; PV = nRT
Where P= Pressure = ?
V= Volume = 8.0 L
n = moles = 8.0
R = Gas constant = 0.0821 L.atm/mol/K
T = 80° c + 273 = 353.15K
Therefore Pressure would be; P = nRT/ V = 8 x 0.0821 x 353.15 / 8 = 28.9atm
Answer:
162.2 g/mol
Explanation:
Molar mass is defined as the mass in 1 mole of the substance. It is calculated by adding the molar mass of the substituents each multiplied by the subscript they have in the formula.
Thus, To calculate molar mass of nicotine having formula, 
Molar mass of C = 12.0107 g/mol
Molar mass of H = 1.00784 g/mol
Molar mass of N = 14.0067 g/mol
Thus, molar mass of nicotine = 
= 162.2 g/mol
Answer:
It would decrease
Explanation:
In an ecosystem, organisms feed on one another for survival due to the fact that energy needed for metabolic activities in individual organisms can only be obtained via food. This question depicts that certain bird population feeds on barley plant in an ecosystem.
However, If a disease attacks the plants in such a way that it destroys the barley plants in the field, this would cause the barley-eating bird population to DECREASE because their food source has been affected.
