When solid aluminum metal is reacted with diatomic chlorine gas, solid aluminum chloride is formed. This reaction is an example of synthesis or chemical combination in which two elements, aluminum and chlorine combine to form a new compound aluminum chloride.
Word equation: Aluminum (s)+ Chlorine (g)---> Aluminum chloride(s)
Molecular formula of the product formed is
.
Therefore the balanced chemical equation representing the reaction of solid aluminum with gaseous dichlorine can be represented as,

1,2-dimbromopropane would be something like C which is the second best answer.
B would be correct if it had another carbon.
A is like C but incorrect for the same reason. 1,2-dibromoethane is what A is.
The answer has to be D where the bromines are right across from each other.
Answer: 60 grams
Explanation: (60 ml)*(1g/ml) = 60g
