When sodium oxalate reacts in solution with lanthanum (III) chloride, lanthanum (III) oxalate is precipitated. a) Write a balanced equation?
b) What is the molarity of the lanthanum (III) chloride solution if 25.0 mL of it is required to react with 13.85 mL of 0.0225 M sodium oxalate?

Once similarity and one difference between a mixture of elements and a mixture of compounds

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.
