Answer: 0.5 g/cm^3
Density equals mass divided by volume so..
60/120 is 0.5 g/cm^3
Answer:
Aluminum is a shiny, silvery white colored metal that is light in weight and strong. Th density of aluminum is 2.7 g/mL, which means the metal will sink in water, but is still relatively light
Hope this helps (:
Mark me brainliest if its good for you :D take care.
Answer:
The forward reaction is occurring at a faster rate than the reverse reaction.
Explanation:
Reaction quotient (Q) of the given reaction is -
![Q=\frac{[NO]^{2}}{[N_{2}][O_{2}]}](https://tex.z-dn.net/?f=Q%3D%5Cfrac%7B%5BNO%5D%5E%7B2%7D%7D%7B%5BN_%7B2%7D%5D%5BO_%7B2%7D%5D%7D)
where [NO], ![[N_{2}]](https://tex.z-dn.net/?f=%5BN_%7B2%7D%5D)
and ![[O_{2}]](https://tex.z-dn.net/?f=%5BO_%7B2%7D%5D)
represents concentrations of respective species at a certain time.
Here = 0.80 M, = 0.050 M and [NO] = 0.10 M
So, 
Hence 
It means that forward reaction is faster than reverse reaction at that point. Because then only concentration of NO is higher than concentrations of and which makes Q higher than K.
Answer:
He should notify the teacher!
Explanation:
The choices are true about the characteristic of a strong base, except for it having a concentration of above 1.0 M. Therefore, the answer is letter A. The concentration of the base is not a very important as to how strong really the base is.
