Answer:
Option A. The reaction would shift to balance the change.
Explanation:
According to Le Chatelier's principle, if an external constrain such as change in concentration, temperature or pressure is imposed on a chemical system in equilibrium, the equilibrium will shift in order to neutralize the effect.
If the equilibrium of a weak acid dissociation reaction is upset, the equilibrium will shift to balance the change as explained by Le Chatelier's principle.
D) A medium. They cant travel through space or black holes and space is a vacuum
Answer:
the percentage error is
50.1%
Explanation:
given that
Mole of NH₃ = 500mole
Volume of container = 1.92l
temperature = 300k
lets calculate the pressure of ammonia gas using both ideal gas equation and vanderwal’s equation
PV = nRT
P = 
=
P = 283 atm - 71.0 atm = 42.7 atm
The percentage error in ideal gas equation is
% error = 
%
= 
%
%error = 50.1%
Answer:
1 litre of 1.0 M NaCl
Explanation:
When an ionic compound dissolves in water, it dissociates into ions. Consider the dissolution of sodium chloride in water;
NaCl(s) ------> Na^+(aq) + Cl^-(aq)
Hence, two solute particles are obtained from each formula unit of NaCl, a greater concentration of NaCl will contain a greater number of sodium an chloride ion particles.
Glucose is a molecular substance and does not dissociate in solution hence it yields a lesser number of particles in solution even at the same concentration as NaCl
