A student reacted sodium sulfate with carbon to yield sodium sulfide and carbon dioxide. (a) Write a balanced equation.

(b) How many grams of carbon is need to completely react with 5.00 grams of sodium sulfate?

(c) If the theoretical yield of sodium sulfide is 2.75 g and the student isolated 1.00 g, what is the percent yield?

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.
