Answer:
65 ml
Explanation:
The aluminum will not float , so it will displace a volume of fluid equal to its volume.
13.5 gm / 2.7 gm/ml = 5 ml
the new graduated cylinder measurement will be 60 + 5 = 65 ml
Answer:
2VO + 3Fe2O3 —> V2O5 + 6FeO
Explanation:
The skeletal equation for the reaction is given below below:
VO + Fe2O3 —> V2O5 + FeO
We can balance the equation above by doing the following:
There are 2 atoms of V on the right side and 1 atom on the left side. It can be balance by putting 2 in front of VO as shown below:
2VO + Fe2O3 —> V2O5 + FeO
Now, we have a total of 5 atoms of O on the left and 6 atoms on the right side. We can balance it by putting 3 in front of Fe2O3 and 6 in front of FeO as shown below:
2VO + 3Fe2O3 —> V2O5 + 6FeO
Now, we can see that the equation is balanced
Answer:
58 g/mol
Explanation:
According to Graham's law, the rate of diffusion of a gas (r) is inversely proportional to the square root of its molar mass (M). Butane's rate of diffusion is 3.8 times slower than that of helium, that is, rButane = rHe/3.8, or rHe/rButane = 3.8. Then,
Answer:
The Copernican revolution demonstrated that science was a process of changing ideas.
I believe this would be a chemical compound, yet it is not one of the options present.
