Why does baking bread require a constant input of heat from the oven?

Chemistry
1 answer:
vladimir2022 [97]3 years ago
3 0

<u>Answer:</u>

<em>Baking of bread is an endothermic process. </em>

<u>Explanation:</u>

In order to bake bread a constant supply of heat energy is required. Since absorption of heat takes place while bread gets baked this is an endothermic reaction. <em>The microbe used in bread making is yeast which helps in puffing up the bread. </em>

Puffing up of bread is caused by the release of carbon dioxide by yeast when it feeds on the sugars in the dough.  For yeast to become active it should come in contact with warm water. <em>Thus heat is an essential input in bread making process.  </em>

Please tell me an example of a protein structure that would give positive test with Molisch’s Reagent?
Andru [333]

Answer:

positive reaction for Molisch's test is given by almost all carbohydrates (exceptions include tetroses & trioses). It can be noted that even some glycoproteins and nucleic acids give positive results for this test (since they tend to undergo hydrolysis when exposed to strong mineral acids and form monosaccharides).

A 3.82 g piece of limestone contains 2.62 g of CaCO3
Kobotan [32]

Considering the definition of percentage by mass, the mass percentage of CaCO₃ is 68.59%.

<h3>What is mass percentage</h3>

The percentage by mass expresses the concentration and indicates the amount of mass of solute present in 100 grams of solution.

In other words, the percentage by mass of a component of the solution is defined as the ratio of the mass of the solute to the mass of the solution, expressed as a percentage.

The percentage by mass is calculated as the mass of the solute divided by the mass of the solution, the result of which is multiplied by 100 to give a percentage. This is:

mass percentage=\frac{mass of solute}{mass of solution}x100

<h3>Mass percentage of CaCO₃</h3>

In this case, you know:

  • mass of CaCO₃: 2.62 grams
  • mass of limestone: 3.82 grams

Replacing in the definition of mass percentage:

mass percentage=\frac{2.62 grams}{3.82 grams}x100

<u><em>mass percentage= 68.59 %</em></u>

Finally, the mass percentage of CaCO₃ is 68.59%.
