Question

Write the balanced combustion equation for solid barium. Remember that combustion is a type of synthesis reaction.

2Ba + O2 ➡ 2BaO

Ba + O ➡ BaO

2Ba + O ➡ Ba2O

2Ba + O2 ➡ Ba2O2

Answer 1

Answer 2

Immediately it cannot be B or C. As combustion reactions require O2 instead of O.

Answer 3

its D right?

Answer 4

The product needs to be BaO as that neutralizes the +2 -2 charge. So it should be A.

Answer 5

Ba2O2 could be simplified to BaO so in this case it would be A.

Answer 6

oh i see what you are saying
