Answer:
Nonpolar Solvent. Carbon tetrachloride. CCl4
Explanation:
The other compounds listed are polar;
polar substances are by their nature more soluble in Other polar compounds. NH3 is a gas; so unless it was a very specific compound you needed in ammonia gas, it, being also polar as well as a gas would not be a good choice for this question.
Answer: The equilibrium constant, 
, for the reaction is 0.061.
Explanation:
Initial concentration of 
= 
Equilibrium concentration of = 
The given balanced equilibrium reaction is,
Initial conc. 0.039 M 0 M 0 M
At eqm. conc. (0.039-x) M (x) M (x) M
Given : (0.039-x) = 0.012
x = 0.027
The expression for equilibrium constant for this reaction will be,
![K_c=\frac{[Cl_2]\times [PCl_3]}{[PCl_5]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BCl_2%5D%5Ctimes%20%5BPCl_3%5D%7D%7B%5BPCl_5%5D%7D)
Now put all the given values in this expression, we get :
The equilibrium constant, , for the reaction is 0.061.
Answer:
D. 5
Explanation:
The coefficient will almost always be the whole number in front of the variable.
example
5(x)= 7
The coefficient would be 5.
Answer:
3
Explanation:
The law of conservation of energy states that energy cannot just be created, so answer one is out. Energy also cannot be simply destroyed, so answer to is out as well. From here it gets tricky, since both answers make some sense under these rules. However, absorbed is bassically the same as destroying it leaving only answer three. Answer three <em>does</em> obey these laws, as energy can be converted.
Answer:
Pressure will double
Explanation:
Gay - Lussac Law => P ∝ T with volume and mass held constant.
=> P₁/T₁ = P₂/T₂ => P₂ = P₁T₂/T₁
T₂ = 2T₁
P₂ = P₁(2T₁)/T₁ = 2P₁
Double absolute temperature => double pressure
