The answer to the question is D
Answer:
2Mg + O2 = 2MgO
Explanation:
Al + 3F2 = AlF3 ..... F has 6 on the left and 3 on the right.
Na + F2 = 2NaF ..... Na has 1 on the left and 2 on the right.
2Al + 3O2 = Al2O3 .... O has 6 on the left and 3 on right.
Answer:
The correct answer to the following question will be Option C.
