The polar bear (Ursus maritimus) is a carnivorous bear whose native range lies largely within the Arctic Circle, encompassing the Arctic Ocean, its surrounding seas and surrounding land masses. It is a large bear, approximately the same size as the omnivorous Kodiak bear (Ursus arctos middendorffi).
All baking powders contain sodium bicarbonate (just like baking soda). But baking powder also contains two acids. One of these acids is called monocalcium phosphate. Monocalcium phosphate doesnât react with the sodium bicarbonate while itâs dry.
1 â Most baking powder used today is double acting, which when added causes a reaction between the acid salts and the baking soda, that releases carbon dioxide gas. 2  The second reaction occurs when the batter is placed in the oven which results in expansion of gas cells that causes the batter to rise.
