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.
The anode is the electrode where oxidation occurs and electrons are lost. The cathode is where reduction takes place and electrons are gained. These reactions don't occur separately; they must work together in a reduction-oxidation reaction.For this next section, let's assume the electrodes are zinc and copper.o determine the voltage of any cell, subtract the electrode potential of the anode from that of the cathode and you get the electrode potential of the cell, or voltage. Eo cell = Eo cathode-Eo anode. Corrosion is when metal is gradually destroyed through chemical reactions, and it is a real problem in our daily lives.
