Answer:
C. More NO2 and SO2 will form
Explanation:
 Le Chatelier's Principle : It  predicts the behavior of equilibrium due to change in pressure , temperature , volume , concentration etc
It states that When external changes are introduced in the equilibrium then it will shift the equilibrium in a direction to reduce the change.
In given Reaction SO3 is introduced(increased) .
So equilibrium will shift in the direction where SO3 should be consumed(decreased)
Hence the equilibrium will go in backward direction , i.e

So more and more Of NO2 and SO2 will form 
 
        
             
        
        
        
Radioactive material obeys 1st order decay kinetics,
For 1st order reaction, we have 
k = 

where, k = rate constant of reaction
Given: Initial conc. 100, Final conc. = 6.25, t = 18.9 hours
∴ k = 

 = 0.1467 hours^(-1)
Now, for 1st order reactions: half life = 

 = 4.723 hours.
 
        
        
        
The answer is head-to-tail joining of monomers. Monomer used in condensation have  two functional groups that combine to form amide and ester linkages. When this reaction occurs, water molecules is removed and that is why it is called a condensation reaction.
        
                    
             
        
        
        
Answer:
It's C 
Explanation:
Most garnet found near Earth's surface forms when a sedimentary rock with a high aluminum content, such as shale, is subjected to heat and pressure intense enough to produce schist or gneiss.
