You didn't include much information as to what you were referring too, however I answered a similar question recently to a friend so I'm hoping this is the same question in complete as to yours, if not I apologize.

a.) 2Na(s) + Cl2(g) -----> 2NaCl(s) 
Na --> Na+1 is oxidized 
Cl2 --> Cl- is reduced 

b.) 2HNO3(aq) + 6HI(aq) ----> 2NO(g) + 3I2(s) + 4H2O(l) 
N+5 --> N+2 is reduced 
I-1 --> I2 is oxidized

Give at least one example of how mass and weight are the same. (science)
Paha777 [63]

Answer:

The mass of an object is the same no matter where it is, but the weight of an object changes with the location of that object. For example, the weight of an object on the Moon is 1/6th that of the same object on Earth, while the mass of that object is exactly the same in both places.

What volume of 6.00m hcl can be made from 319 ml of 6.80m hcl?
velikii [3]
So the mole number of 319 ml of 6.80 M HCl is 6.80*319*10^(-3)=2.17 mol. So the volume of 6.00 M HCl needed is 2.17/6.00=0.362 L=362 ml
