Question

Al + Br2 =Ba + O2 =Na + O2 =Cl2 + Mg =​

Answer 1

Объяснение:

2Al+3Br2=2AlBr3

2Ba+O2=2BaO

4Na+O2=2Na2O

Mg+Cl2=MgCl2

Answer 2

It seems like you've provided a series of chemical reactions, but they are not balanced equations. Chemical equations need to be balanced to accurately represent the conservation of mass and atoms in a reaction. I'll help you balance them properly:

1. Aluminum (Al) reacting with Bromine (Br2): 2 Al + 3 Br2 → 2 AlBr3

2. Barium (Ba) reacting with Oxygen (O2): 2 Ba + O2 → 2 BaO

3. Sodium (Na) reacting with Oxygen (O2): 4 Na + O2 → 2 Na2O

4. Chlorine (Cl2) reacting with Magnesium (Mg): Cl2 + Mg → MgCl2

Remember, balanced chemical equations follow the law of conservation of mass, which means that the number of atoms of each element is the same on both sides of the equation.
