What explanation from the evidence within the chemical equation BEST supports the idea that matter is conserved in a chemical reaction? A There are the same number of atoms of oxygen and hydrogen in the reactants as there are in the products. B There are the same number of elements in the reactants as there are in the products. C More reactants, hydrogen and oxygen, were added to make the product, water. D Two reactants, hydrogen and oxygen, combined to make one product, water.

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.
