Answer the following question: Information: - In chemistry, a carbonate is a salt of carbonic acid (HCO), characterized by the presence of the carbonate ion, . The name may also mean an ester of carbonic acid, an organic compound containing the carbonate group C(=O)(O). - Yeasts are eukaryotic, single-celled microorganisms classified as members of the fungus kingdom. The yeast lineage originated hundreds of millions of years ago, and 1,500 species are currently identified. They are estimated to constitute 1% of all described fungal species. Yeasts are unicellular organisms which evolved from multicellular ancestors, with some species having the ability to develop multicellular characteristics by forming strings of connected budding cells known as pseudohyphae or false hyphae. Yeast sizes vary greatly, depending on species and environment, typically measuring 34m in diameter, although some yeasts can grow to 40m in size. Most yeasts reproduce asexually by mitosis, and many do so by the asymmetric division process known as budding. - Dough is a thick, malleable, sometimes elastic, paste made out of any grains, leguminous or chestnut crops. Dough is typically made by mixing flour with a small amount of water and/or other liquid, and sometimes includes yeast or other leavening agents as well as other ingredients such as various fats or flavorings. - Fermentation is a metabolic process that converts sugar to acids, gases, or alcohol. It occurs in yeast and bacteria, and also in oxygen-starved muscle cells, as in the case of lactic acid fermentation. Fermentation is also used more broadly to refer to the bulk growth of microorganisms on a growth medium, often with the goal of producing a specific chemical product. French microbiologist Louis Pasteur is often remembered for his insights into fermentation and its microbial causes. The science of fermentation is known as zymology. - A recipe is a set of instructions that describes how to prepare or make something, especially a culinary dish. It is also used in medicine or in information technology (user acceptance). A doctor will usually begin a prescription with "recipe", Latin for "take", usually abbreviated to Rx or an equivalent symbol. - Baking powder is a dry chemical leavening agent, a mixture of a carbonate or bicarbonate and a weak acid, and is used for increasing the volume and lightening the texture of baked goods. Baking powder works by releasing carbon dioxide gas into a batter or dough through an acid-base reaction, causing bubbles in the wet mixture to expand and thus leavening the mixture. It is used instead of yeast for end-products where fermentation flavors would be undesirable or where the batter lacks the elastic structure to hold gas bubbles for more than a few minutes, or to speed the production. Because carbon dioxide is released at a faster rate through the acid-base reaction than through fermentation, breads made by chemical leavening are called quick breads. - In inorganic chemistry, bicarbonate (IUPAC-recommended nomenclature: hydrogen carbonate) is an intermediate form in the deprotonation of carbonic acid. It is a polyatomic anion with the chemical formula . - The Belgian waffle is a type of waffle popular in Europe and North America . What is known in North America as the '' Belgian waffle '' does not exist in Belgium . No single type of waffle is identified as a '' Belgian waffle '' within Belgium itself , where there are a number of different varieties , including the Brussels waffle and the Liege waffle . Compared to the standard American waffle , it is identified by its larger size , lighter batter , larger squares , and a higher grid pattern that forms deep pockets . It also traditionally uses yeast instead of baking powder , although contemporary Belgian waffles are often made with baking powder . In North America , they are often eaten as a breakfast food ; toppings vary from whipped cream , confectioners sugar , soft fruit , and chocolate spread , to syrup and butter or margarine . Alternatively , they are served with vanilla ice cream and fresh fruit ( such as strawberries ) as a dessert . - Quick bread is any bread leavened with leavening agents other than yeast or eggs. An advantage of quick breads is their ability to be prepared quickly and reliably, without requiring the time-consuming skilled labor and the climate control needed for traditional yeast breads. - A waffle is a leavened batter or dough cooked between two plates, patterned to give a characteristic size, shape and surface impression. There are many variations based on the type of waffle iron and recipe used. Waffles are eaten throughout the world, particularly in Belgium, which has over a dozen regional varieties. - In computer science, ACID ("Atomicity, Consistency, Isolation, Durability") is a set of properties of database transactions. In the context of databases, a single logical operation on the data is called a transaction. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction. - A leaven , often called a leavening agent (and also known as a raising agent), is any one of a number of substances used in doughs and batters that cause a foaming action (gas bubbles) that lightens and softens. An alternative or supplement to leavening agents is a mechanical action by which air is incorporated. Leavening agents can be biological or synthetic chemical compounds. The gas produced is often carbon dioxide, or occasionally hydrogen, or another. - A waffle iron is a utensil or appliance used to cook waffles. It usually consists of two hinged metal plates, molded to create the honeycomb pattern found on waffles. The iron is heated and either batter is poured or dough is placed between the plates, which are then closed to bake the waffle. - Carbon dioxide (chemical formula CO) is a colorless and odorless gas that is vital to life on Earth. This naturally occurring chemical compound is made up of a carbon atom covalently double bonded to two oxygen atoms. Carbon dioxide exists in Earth's atmosphere as a trace gas at a concentration of about 0.04 percent (400 ppm) by volume. Natural sources include volcanoes, hot springs and geysers, and it is freed from carbonate rocks by dissolution in water and acids. Because carbon dioxide is soluble in water, it occurs naturally in groundwater, rivers and lakes, in ice caps and glaciers and also in seawater. It is present in deposits of petroleum and natural gas. - Belgium , officially the Kingdom of Belgium, is a sovereign state in Western Europe bordered by France, the Netherlands, Germany, Luxembourg, and the North Sea. It is a small, densely populated country which covers an area of and has a population of about 11million people. Straddling the cultural boundary between Germanic and Latin Europe, Belgium is home to two main linguistic groups: the Dutch-speaking, mostly Flemish community, which constitutes about 59% of the population, and the French-speaking, mostly Walloon population, which comprises 41% of all Belgians. Additionally, there is a small group of German-speakers who live in the East Cantons located around the High Fens area, and bordering Germany.
