You arrive in my class 45 seconds after leaving math which is 90 meters away. How fast did you travel?

Speed is 2

Explanation:

Speed = distance ÷ time

90/45=2

answer : the anode is the positive electrode so attracts negative ions. at the anode, negative ions lose electrons (they are oxidised).the resulting product depends on the ionic substance but is non-metal and is often a gas. examples are: chlorine, bromine, iodine and oxygen. (the negative electrode is called the cathode.

explanation: negatively charged chloride ions move to the positive electrode. the atoms join up in pairs to form cl 2 molecules, so chlorine gas is formed at the positive electrode. during the electrolysis of molten salts, a metal forms at the cathode and a non-metal forms at the anode.
