Question 25 of 25Which of the following are correctly balanced reactions?Check all that apply.A. 2Na + Br2 → NaBrB. S+ 3Cl2 → SCIOO C. CaS + FeO → 2FeS + 2CaoD. 2H2 + O2 → 2H20

Answer 1

B and D.

Step-by-step explanation:

A reaction is correctly balanced when there is the same amount of each element in each side of the reaction.

The balanced reactions are:

`S+3Cl_2\rightarrow SCl_6`

Because in each side of the reaction there are: 1S and 6 Cl.

And:

`2H_2+O_2\rightarrow2H_2O`

Because in each side of the reaction there are: 4H and 2O.
