Answer:
Explanation:
Molarity of the solution measures number of moles of a solute per litre of solution.
Molarity = volume of solution in litres/number of moles of solute dissolved in solution
Volume of solution in litres = 0.86 L
Also, 1.34 mole sample of LiCl dissolves in water
So,
Molarity of the Solution =
Answer:
Bohr thought that electrons orbited the nucleus in circular paths; whereas in the modern view atomic electron structure is more like 3D standing waves. Bohr built upon Rutherford's model of the atom. ... He believed that electrons moved around the nucleus in circular orbits with quantised potential and kinetic energies.
Explanation:
Answer:
2 Na + 1 Cl2 -> 2 NaCl
Explanation:
The answer is really simple, because if you have 1 nonmetal element that has a subscript of 2, you need to multiply the product and the first reactant by 2 to balance it.
Answer:
It has a different value at different temperatures.
Explanation:
For any system in equilibrium, the molar concentration of all the species on the right hand side are related to the molar concentrations of those at the left side by a constant known as the equilibrium constant.
The equilibrium is a constant at a given temperature as it is temperature dependent.
A change in temperature of an equilibrium system shifts the system to a new equilibrium point. A rise in temperature actually shifts equilibrium position to the direction that absorbs heat and vice versa.
The shift in equilibrium as a result of temperature change is actually a change in the value of the equilibrium constant. Equilibrium constant is represented as
The derivation of the equilibrium constant is based on the Law of Mass Action which states: the rate of a chemical reaction is proportional to the product of the concentrations of the reacting substances.
