Part A
1. mass of apparatus before mixing 1st trial. 5.288g 2nd trial 4.317g 3rd 5.387g
2. observations on mixing turned white, bubbly
3. mass of apparatus after mixing. 5.450g, 4.941g, 6.137g
Part B
1. mass of bottle water cap and tablets 68.2 63.4 65.3
2. observations bubbling disolves. 3
mass of aparatus after mixing 33.6 40.5 32.1
25.5 22.9 29.3
Part C.
mass of appartus berfore mixing. 3.962 3.962 3.948
1. for each experiment list the observations that suggest that a chemical reaction has taken place.
2. part A= dropped part b= dropped then raised
3. yes beacause they are close to each other
