The measure of a major arc is C10-448A-888484be x Â° $%# greater than 180, and equal to 360 minus the measure of the minor arc with the same endpoints. m âADB = 360 - mAB â = 360 - x A semicircle is an arc with endpoints that lie on a diameter.
Process Chemicals Corrosion. Chlorine. The flow rate of liquid chlorine through carbon steel pipework is restricted to 2 m/s to avoid removing the ferric chloride coating on the pipe surface which protects against erosion / corrosion of the carbon steel. Wet chlorine gas corrodes mild steel.
The oxidation state of sodium is +1. 5. Example: Chlorine. In a chlorine molecule, the chlorine atoms are. covalently bonded. The two atoms share electrons. equally and the oxidation state is 0. 6. Example: Chlorine. The two atoms of a hydrogen chloride molecule are covalently. bonded. The electrons are not shared equally because chlorine is. more electronegative than hydrogen. There are no ions but the oxidation state of chlorine in HCl is -1 and. the oxidation state of hydrogen is +1.
