The distance between a carbon atom and an oxygen atom in the co molecule is 0.63
<h3>What is the distance?</h3>
Distance is the measurement of the farness of two objects from each other.
The distance between the molecules can be calculated by the given formula 

Putting the values in the equation

Thus, the distance between a carbon atom and an oxygen atom in the co molecule is 0.63

Answer:
∆H = negative and ∆S = positive.
Explanation:
The reaction given in the question is spontaneous at room temperature , 
hence , 
The the gibbs free energy , i.e. ,∆G will be negative for  spontaneous reaction 
According to the formula , 
∆G = ∆H -T∆S 
The value of ∆G can be negative , if  ∆H has a negative value and  ∆S has a positive value , because , T∆S  , has a negative sign .
Hence , the answer will be , ∆H = negative and ∆S = positive.
 
        
             
        
        
        
Answer:
Q < Ksp
Explanation:
The general equilibrium of a constant product solubility, ksp, is:
AB ⇄ A⁺ + B⁻
<em>Where Ksp is defined as:</em>
Ksp = [A⁺] [B⁻]
When [A⁺] [B⁻] = Ksp, the solution is saturated or oversaturated because there are the maximum amount of ions that solution can dissolve. 
When the solution is oversaturated, AB is produced.
Now, in a unsaturated solution, the [A⁺] [B⁻] is less than the maximum amount that can be dissolved. That means:
[A⁺] [B⁻] = Q < Ksp
Q is defined in the same way than Ksp, just in Q the system is not in equilibrium.
Right answer is:
<h3>Q < Ksp</h3>
