Which probing question lies within the scope of physics?

All substances taking part in a certain interaction are shown below: Butane is written followed by an addition sign followed by Oxygen followed by an equal to sign followed by Carbon dioxide followed by an addition sign followed by Water. Just below Butane 29 grams is written and just below Carbon dioxide and Water is a parentheses below which 133 grams is written Which of the following is the correct estimate of the amount of oxygen used in the interaction? Sum of 133 g and 29 g Difference between 133 g and 29 g Twice the sum of 133 g and 29 g Twice the difference between 133 g and 29 g
