Jonathan is studying solutions in his chemistry class. The teacher instructs the students to measure 2 tablespoons of salt into a beaker. Next, Jonathan is told to measure 4 times that amount of water and add it to the beaker. How much water should Jonathan add to the beaker? tablespoons

what experimental evidence led scientists to change from the previous model to this one?

a few of the positive particles aimed at a gold foil seemed to bounce back.

the colors of light emitted from heated atoms had very specific energies.

experiments with water vapor showed that elements combine in specific proportions.

cathode rays were bent in the same way whenever a magnet was brought near them.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
