Answer: The value of the equilibrium constant Kc for this reaction is 0.088
Explanation:
where,
x = given mass
M = molar mass
= volume of solution in L
Equilibrium concentration of 
= 
Equilibrium concentration of 
= 
Equilibrium concentration of 
= 
The given balanced equilibrium reaction is,
The expression for equilibrium constant for this reaction will be,
![K_c=\frac{[CaO]\times [CO_2]}{[CaCO_3]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BCaO%5D%5Ctimes%20%5BCO_2%5D%7D%7B%5BCaCO_3%5D%7D)
Now put all the given values in this expression, we get :
Answer:
b. 4.4
Explanation:
pH is related to the concentration of H₃O⁺ through the following equation:
pH = -log([H₃O⁺]) = -log(4 x 10⁻⁵)
pH = 4.4
Answer:
Solar power
Or in some cases, from heat from the sun. ... Solar energy is a renewable free source of energy that is sustainable and totally inexhaustible, unlike fossil fuels that are finite. It is also a non-polluting source of energy and it does not emit any greenhouse gases when producing electricity.
Explanation:
True because it has more power than coal burning
