The equilibrium concentration of 
.
The equilibrium concentration of 
.
The equilibrium concentration of 
.
Explanation:
Answer:
The equilibrium concentration of HCl is 0.01707 M.
Explanation:
Equilibrium constant of the reaction = 
Moles of 
Concentration of ![[PCl_3]=\frac{0.280 mol}{1.00 L}=0.280 M](https://tex.z-dn.net/?f=%5BPCl_3%5D%3D%5Cfrac%7B0.280%20mol%7D%7B1.00%20L%7D%3D0.280%20M)
Moles of 
Concentration of ![[Cl_2]=\frac{0.280 mol}{1.00 L}=0.280M](https://tex.z-dn.net/?f=%5BCl_2%5D%3D%5Cfrac%7B0.280%20mol%7D%7B1.00%20L%7D%3D0.280M)
Initial: 0.280 0.280 0
At eq'm: (0.280-x) (0.280-x) x
We are given:
![[PCl_3]_{eq}=(0.280-x)](https://tex.z-dn.net/?f=%5BPCl_3%5D_%7Beq%7D%3D%280.280-x%29)
![[Cl_2]_{eq}=(0.280-x)](https://tex.z-dn.net/?f=%5BCl_2%5D_%7Beq%7D%3D%280.280-x%29)
![[PCl_5]_{eq}=x](https://tex.z-dn.net/?f=%5BPCl_5%5D_%7Beq%7D%3Dx)
Calculating for 'x'. we get:
The expression of 
for above reaction follows:
![K_c=\frac{[PCl_5]}{[PCl_3][Cl_2]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BPCl_5%5D%7D%7B%5BPCl_3%5D%5BCl_2%5D%7D)
Putting values in above equation, we get:
On solving this quadratic equation we get:
x = 0.228, 0.344
0.228 M < 0.280 M< 0.344 M
x = 0.228 M
The equilibrium concentration of .
The equilibrium concentration of .
The equilibrium concentration of .
Answer: m = 17.5 g Cl
Explanation: To find the mass of Cl we will need to convert the moles of Cl to mass using the relationship of 1 mole = molar mass of Cl.
0.500 mole Cl x 35 g Cl / 1 mole Cl
= 17. 5 g Cl
4NH₃(g) + 3O₂(g) ⇄ 2N₂(g) + 6H₂O(g) is the balanced equation.
<h3>What is balanced equation?</h3>
If both the reactants and the products have the same number of atoms and total charge in each component of the equation, the equation describing the chemical reaction is said to be balanced. In other words, the mass and charge in the reaction are equal on both sides.
A chemical equation is the symbolic representation of a chemical reaction in the form of symbols and formulae, where the reactant entities are given on the left and the product entities on the right, with a plus sign between the entities in both the reactants and the products and an arrow that points towards the products, showing the direction of the reaction.

IPSPs are local hyperpolarizations.
Option B
<u>Explanation:</u>
The Inhibitory Post Synaptic Potentials are basically resultant of local hyper polarization and by then they degrade to depolarization. These are synaptic potentials which causes the neuron of post synapse to engage in lesser generation of action potential.
The local hyper polarization is achieved as the post synapse membrane has the negative potential more than that of resting membrane, then the condition becomes hyper polarization. In order to achieve so, the action potential must under go depolarization and hence it degrades to depolarization.
