Since KCl is a neutral molecule, the sum of the oxidation states of the atoms equals zero. We know that potassium (K) has an oxidation of +1 since it is a group 1 element. So, K +1 Cl -1 ===> KCl 0 OR KCl. Thus, the charge on potassium (K) in KCl is +1. Upvote • 2 Downvote.

Assuming you meant KCl (potassium chloride) instead of KC1, and KClO 3 (potassium chlorate) instead of KC1O3; the answer would be: Moles of KClO 3 = 89.0g KClO 3 x (1mol KClO 3 /122.55 g KClO 3) = 0.7262 mol KClO 3. Note: From the formula, KClO 3, it means in every 1 mol of KClO3 ... Polar molecules will be attracted to each other by either hydrogen bonding or dipole-dipole interactions. These intermolecular forces are made possible by a large difference in electronegativity values for two atoms bonded to each other. In water, the electronegativity difference between oxygen (3.5) and hydrogen (2.1) is 1.4 (3.5-2.1=1.4).
