Answer: increasing volume
Explanation: adding a catalyst would increase reaction time and increasing  INCREASING concentration definently makes reaction time alot faster increasing pressure actually makes it more concentrated, so no it is not

Answer:
It comes from same parent material.
Explanation:
The two rocks have some similar minerals which indicates that they are comes from the same parent material but with the passage of time it is mixed with other minerals due to which they are some different in composition from one another so we can conclude that they comes from the same parent material due to the presence of some similar minerals.
 
        
             
        
        
        
Answer:
6,613 M
Explanation:
Dilution is the process of reducing the concentration of a solute in solution, mixing initial solution with more solvent.
The concentration of Solution B is:
23,881 M ×  = 9,552 M
Because the initial eight parts are diluted to 12+8 parts.
Thus, concentration of solution C is:
9,552 M ×  = 6,613 M
I hope it helps!
