If a customer separately arranges and pays for delivery of a taxable item by a third party, the seller of the item will only collect sales tax on its charge (see Delivery-only services, below).f the product or service being sold is not taxable, any charge to the customer for shipping or delivery is also not taxable. This also applies when the customer gives the seller a valid resale certificate or other exemption document.
In a discharging battery (Galvanic cell), the anode is the negative terminal, and cathode is positive. In a recharging battery (Electrolytic cell), the opposite happens, anode is positive and cathode is negative. Here, the mnemonic PRANC (rhymes with prank) can be used, P- Positive.
1 The metal-A electrode is the anode. 2  The cathode is the electrode where reduction (gain of electrons) takes place; in a galvanic cell, it is the positive electrode, as less oxidation occurs, fewer ions go into solution, and less electrons are left on the electrode.
