(3)4. For making cake Baking powder is used. If at home your mother uses Bakingsoda instead of Baking powder;-(3)a) How will it affect the taste of the cake and why?.b) How can Baking soda are converted into Baking powder.c) What is the role of tartaric acid added to Baking soda? |
|
Answer» Answer: A)If only sodium hydrogen carbonate (baking soda) is used in making CAKE, then sodium carbonate formed from it by the action of heat (during baking)give a bitter taste to cake. ... (c) Tartaric acid NEUTRALISES the sodium carbonate formed during decomposition hence, making the cake tasty and not bitter in taste b) Baking soda is CONVERTED into baking powder by adding tartaric acid and starch to the baking soda. Baking soda is basic in nature and it is bitter in taste. On the other hand tartaric acid is a weak and mild acid. c) The ADVANTAGE of using baking powder is that tartaric acid present in baking powder reacts with sodium carbonate ( ) produced during decomposition of and neutralizes it. ... (c) Tartaric acid neutralises the sodium carbonate formed during decomposition hence, making the cake tasty and not bitter in taste. Hope it helps you Pls mark me brainliest Below cake made by me

What is molar mass of an gas if the weight of the gas is .22 g and volume is 112 ml |
|
Answer» it's molar MASS is 4,400g. EXPLANATION: molar mass of a GAS is the mass of the gas at STP or 22,400ml volume. given weight of the gas is 22g at 112 ml.so, 22g --------> at 112ml xg --------> at 22,400ml so,x=22,400*22/112 then, on SOLVING x will be equal to 4,400g. so, the molar mass of the gas is 4,400g |

Monomer and polymer definationwith example |
|
Answer» Answer: Monomers The word monomer comes from mono- (one) and -mer (part). Monomers are small molecules which may be joined together in a repeating fashion to form more complex molecules called polymers. Monomers form polymers by forming chemical bonds or binding supramolecularly through a process called polymerization. Sometimes polymers are made from bound groups of monomer subunits (up to a few dozen monomers) called oligomers. To qualify as an oligomer, the properties of the molecule need to change significantly if one or a few subunits are added or removed. Examples of oligomers include collagen and liquid paraffin. A related term is "monomeric protein," which is a protein that bonds to make a multiprotein complex. Monomers are not just building blocks of polymers, but are important molecules in their own right, which do not necessarily form polymers unless the conditions are right. Examples of MonomersExamples of monomers include vinyl chloride (which polymerizes into polyvinyl chloride or PVC), glucose (which polymerizes into STARCH, cellulose, laminarin, and glucans), and amino acids (which polymerize into PEPTIDES, polypeptides, and proteins). Glucose is the most abundant natural monomer, which polymerizes by forming GLYCOSIDIC bonds. PolymersThe word polymer comes from POLY- (many) and -mer (part). A polymer may be a natural or synthetic macromolecule comprised of repeating units of a SMALLER molecule (monomers). While many people use the term 'polymer' and 'plastic' interchangeably, polymers are a much larger class of molecules which includes plastics, plus many other materials, such as cellulose, amber, and natural rubber. Lower molecular weight compounds may be distinguished by the number of monomeric subunits they contain. The terms dimer, trimer, tetramer, pentamer, hexamer, heptamer, octamer, nonamer, decamer, dodecamer, eicosamer reflects molecules containing 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, and 20 monomer units. Examples of PolymersExamples of polymers include plastics such as polyethylene, silicones such as silly putty, biopolymers such as cellulose and DNA, natural polymers such as rubber and shellac, and many other important macromolecules.
