Answer:
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.
Although traffic in rural areas is lower, these roads are as dangerous as the highways. There are some potential hazards due to the lack of transparency of the areas where high levels of accident are recorded, and which should be marked. Installing warning signs in advance, and at intersections, will provide drivers information about the intersection, which is why they act more responsibly before the upcoming crossroads.
The answer is: warning.
