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.
Silver chloride is also found as a corrosion product of silver 7. Chlorine gas (from bleach) and sodium chloride (from human secretion) react with silver to produce silver chloride. Pure silver chloride is a white or transparent compound. Encrustation of soot and dust combined in this silver chloride corrosion layer can turn it into a darker colour.
