Answer: The equilibrium constant
for this reaction is 0.088
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as ![K_c](https://tex.z-dn.net/?f=K_c)
For the given chemical reaction:
![NO+NO_2(g)\rightarrow N_2O_3](https://tex.z-dn.net/?f=NO%2BNO_2%28g%29%5Crightarrow%20N_2O_3)
The expression for
is written as:
![K_c=\frac{[N_2O_3]}{[NO_2][NO]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BN_2O_3%5D%7D%7B%5BNO_2%5D%5BNO%5D%7D)
![K_c=\frac{(1.3)}{(3.9)\times (3.8)}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%281.3%29%7D%7B%283.9%29%5Ctimes%20%283.8%29%7D)
![K_c=0.088](https://tex.z-dn.net/?f=K_c%3D0.088)
The equilibrium constant
for this reaction is 0.088
2 to 4. Im pretty sure you might have to check me on it but as far as i know 2 to 4 years.

Answer:low lattice energy for the solid and a high hydration energy for its ions
Explanation:
The lattice energy is the energy that holds the ions in the crystal lattice together. This energy must also be supplied for the lattice to disintegrate into its component ions. When this energy is lower than the energy released during the hydration of ions, the lattice easily breaks apart releasing the ions which are now strongly hydrated and the ionic solid is said to be soluble in water. Hence, solubility is favoured by lower lattice energy and higher hydration energy.
Answer:
-OOH
Explanation:
This forms an acid if it comes in contact with a metal
212 g of sodium carbonate (Na₂CO₃)
Explanation:
We find the number of moles of sodium carbonate (Na₂CO₃) using the following formula:
molar concentration = number of moles / volume (L)
number of moles = molar concentration × volume (L)
number of moles of Na₂CO₃ = 4 × 0.5
number of moles of Na₂CO₃ = 2 moles
Now we calculate the mass of sodium carbonate (Na₂CO₃):
number of moles = mass / molar weight
mass = number of moles × molar weight
mass of Na₂CO₃ = 2 × 106
mass of Na₂CO₃ = 212 g
