If 146.5 g of Chromium(III) chlorate decomposes, how many liters of oxygen can be produced at STP?

2 Cr(ClO3)3 → 2 CrCl3 + 9 O2

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.

Calculate the number of grams of sodium in 3.00 g of each sodium-containing food additive.

Food can lose electrons to air. this loss of electrons can create free radicals that destroy chemical bonds, hence spoiling the food. which term describes this process?
