Someone plz ans this question

 

Dear Student,

The baker had forgotten to add baking powder. Baking powder is basically a mixture composed of baking soda, tartaric acid and starch. It is used in making cakes, breads and other baked food items. While preparing the dough, baking powder is added to the flour. When baking powder mixes with water, then the sodium hydrogencarbonate reacts with tartaric acid to evolve carbon dioxide gas which gets trapped in the wet dough and bubbles out slowly making the cake to rise and hence 'soft and spongy'. This gas is also released when the dough is heated due to the decomposition of sodium hydrogencarbonate. The involved equations can be shown as follows:

NaHCO₃ + H⁺ →Na⁺ + CO₂ + H₂O
