A kilogram is a unit of mass. A meter is a unit of measurement, a Liter is volume and a kelvin is temperature
Answer:
Chemistry, the science that deals with the properties, composition, and structure of substances (defined as elements and compounds), the transformations they undergo, and the energy that is released or absorbed during these processes
Electric signals that travel back and forward
Answer:
B. It will become more green and brown
Explanation:
Le Chateliers principle states that when a constraint such as change in concentration, volume, pressure or temperature is imposed on a reaction system at the equilibrium, the equilibrium position will shift in such a way as to annul the constraint. Let us see how this applies to the equation under consideration.
If the system is at equilibrium and more ICl3 is added to the system, the equilibrium will shift towards the left hand side (more reactants are formed). This implies that the colour of the system will become more green and brown since there are more reactants now in the system.
PKa= 4.9 therefore ka= 10^-4.9= 1.259x10^-5
= 0.05
= 0.10
Therefore 1.259x10^-5 =
Rearrange the equation to make the concentration of hydrogen the subject.
Therefore
Therefore
pH= -log [
] = -log(2.513*10^-5)= 4.59.
