Answer: The answer is a. limiting, excess. I took the test.
Explanation:
I think it may be B, because this reaction may have produced heat &/or light. I think energy could be decreased that way.. sorry I couldn’t be a better help but I hope this sort of gives you an idea ;w;
Aluminium, To find the correct answer we can find out the density of the sample,
Using the density formula which is,
Density ρ =
Here, Mass = 13.5 g; Volume = 5
on calculating we get,
Density =
Which shows that, aluminum has this density. Aluminum has density as
So, the correct answer will be aluminum.
