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.
Minerals: Chloride. The element chlorine itself is a poisonous gas that is soluble in water; in nature and in our body, it exists primarily as the chloride anion, the negatively charged ion that joins with cations such as sodium to make salt (sodium chloride) and with hydrogen to make stomach acid (hydrochloric acid).
