Answer:
Volume of water at this temperature is 27.2 mL
Explanation:
We know that 
Here density of water is 0.992 g/mL
Here mass of water is 27.0 g
So 
                          = 
                          = 27.2 mL
 
        
             
        
        
        
Answer:
According to Kinetic Molecular Theory, an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often. If the reaction is kept at constant pressure, they must stay farther apart, and an increase in volume will compensate for the increase in particle collision with the surface of the container.

Thus 174 protons would make at most 6 copper atoms. However, it would take 174 extra electrons (29 per atom) and even more neutrons than that to construct neutral copper atoms with stable nuclei.
 
        
             
        
        
        
Answer:  
NaZ + H2O <----> HZ + OH- 
 [OH-] = [HZ] 
 [NaZ] = 0.15 M 
 pH = 10.7, so the pOH = 14-10.7 = 3.3; [OH-] = 10^-3.3 = 5.01E-4 
 kb = [OH-][HZ]/[NaZ] = (5.01E-4)^2/0.15 = 1.67E-6 
 ka = kw/kb = 1E-14/1.67E-6 = 5.99E-9 = 6.0E-9
