This fin variety most closely resembles wild betta splendens, as long tails and the subsequent tail types were all selectively bred by human intervention. These fish are often mistaken for female bettas, who generally have shorter fins, but this is an entirely different variety of betta.Males can be distinguished by females by their longer ventral fins, more pointed/angled anal fin, and slightly different body shape.ouble Tail. A fin type in which the caudal (tail) fin is split into two lobes instead of one. This is a genetic trait, and the same genetics that cause this double-tail cause the dorsal and anal fins to be very broad and the body to be shorter, which predisposes these fish to swimbladder problems.
Oxygen = three ions each with a charge of -2 = 3 x -2 = -6. The overall charge of the polyatomic ion is -2. This means that the oxidation number of the carbon must be +4. Total charge = +4 + -6 = -2. Here is a video which discusses this topic by discussing how to determine oxidation numbers of elements in the bicarbonate and dichromate ions. Video from: Noel Pauller.
Bicarbonate (HCO 3 â) is alkaline, and a vital component of the pH buffering system of the human body (maintaining acid-base homeostasis). 70-75% of CO 2 in the body is converted into carbonic acid (H 2 CO 3), which can quickly turn into bicarbonate.he prefix bi in bicarbonate comes from an outdated naming system and is based on the observation that there is two times as much carbonate (CO 3) per sodium ion in sodium bicarbonate (NaHCO 3) and other bicarbonates as in sodium carbonate (Na 2 CO 3) and other carbonates.
