Which of the following does not show the law of conservation of mass?

a. 24 g of mg burn in 32 g o2 to produce 56 g of mgo.

b. 24 ml of mg burn in 32 ml o2 to produce 56 ml of mgo.

c. 2 atoms of mg react with 1 molecule of o2 to produce 2 units of mgo.

d. 1 atom of mg reacts with 1 atom of o to produce a unit of mgo that contains 2 atoms.

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
