Answer: The value of the equilibrium constant Kc for this reaction is 3.72
Explanation:
Equilibrium concentration of 
= 
Equilibrium concentration of 
= 
Equilibrium concentration of 
= 
Equilibrium concentration of 
= 
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 
For the given chemical reaction:
The expression for is written as:
![K_c=\frac{[NO_2]^3\times [H_2O]^1}{[HNO_3]^2\times [NO]^1}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BNO_2%5D%5E3%5Ctimes%20%5BH_2O%5D%5E1%7D%7B%5BHNO_3%5D%5E2%5Ctimes%20%5BNO%5D%5E1%7D)
Thus the value of the equilibrium constant Kc for this reaction is 3.72
Answer: The correct option is, They are different units of concentration.
Explanation: Molarity : It is defined as the number of moles of solute present in one liter of solution.
Answer:
A saturated solution
Explanation:
A saturated solution is a solution which has dissolved as much solute as it can dissolve at a given temperature. If more solutes are added, a saturated solution would not dissolve it. Such solution has reached its carrying capacity.
If the temperature changes, the solution might be able to dissolve more solutes in it.
An undersaturated solution is one in which does not contain enough dissolved solutes in it at a given temperature.
Fire expends ENERGY which is a by-product of conversion of matter.
<span>The calories or therms of a fire equal a certain amount of mass. </span>
<span>When MATTER (Electron) and ANTI-MATTER (Positron) collide they don't inhillate each other with nothingness, they always realse TWO gamma particles. </span>
<span>The ENERGY of the TWO gamma particles CONSERVES the MASS of the ELECTRON and The POSITRON </span>
<span>This is what Einstein meant by E=mc2 </span>
<span>ENERGY has physical properties than can be measured. </span>
<span>These properties equal the mass that no longer exists after you measure the mass BEFORE and AFTER </span>
<span>The AFTER MASS + the ENERGY MUST equal the BEFORE MASS to at least 99.999% </span>
<span>You must take heat, light and other PARTICLES into consideration. </span>
<span>Their MASS plus their ENERGY</span>
