Help please ill give brainlest! A student was adding baking soda and vinegar to a bottle. They then put a balloon on top of the bottle immediately after adding them together. The student observed that the balloon inflated and got larger. The student then predicted that the chemical reaction between the vinegar and the baking soda had created brand new matter, and would have more mass at the end of the reaction. Would you agree with the student’s prediction or not? Explain your answer.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
