3050÷140
=21.79g
Therefore the was a mass of 21.79 grams in the sample
Answer:
When the solution turns clear, either at the end of the reaction or when you add sufficient cyclohexene
Explanation:
The colour of bromine in the solution is usually yellow, however when the solution turns clear, this shows that all the bromine has been consumed.
Another way to make sure that all the bromine molecules are consumed is by addition of an unsaturated hydrocarbon like cyclohexene. Cyclohexene will consume the bromine molecules and the solution will become clear, while the cyclohexene becomes more saturated by becoming bromo cyclohexane.
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.
