No, the reaction was not carried out in a closed system
Explanation:
Recall that a closed system is one in which there is no exchange of materials nor energy. Hence there is no movement of matter in or out of the system. The total mass and energy present in the system is constant.
On the reactant side we have that the total mass of baking soda and vinegar is 47g + 13 g = 60g.
However on the product side, we have only a total of 56g which implies that a mass of 4g was lost in the reaction. This loss of mass can not happen in a closed system.
Hence the system is not a closed system because some mass was lost.
