Answer:
Chromium
Explanation:
Cr has 24 atomic number and mass number 52
Answer:
D
Explanation:
The answer is D. I'm not sure that it is a solid. I don't think it is a ppte, which is the only way it can be a true solid. It is ionic if the reaction is taking place in water and there is someway to start the reaction. Be that as it may, the internal balace numbers of the chemical produced is the only possible answer. The balanced eq;uatioon is
2Al + 3Br2 ==> 2AlBr3
Add 4H2 in the reactant side, that will give you 4H2O in the product side.
