Describe how to find calorie content in food

Chemistry
1 answer:
Fiesta28 [93]3 years ago
4 0

<u>To find the calorie content in food:</u>

Importantly, a calorie will not be considered as full or empty and not a thing too.  You cannot tie calories in a bottle. A calorie is a unit of measure of energy. We can also say that, it is the energy amount that is needed to rise the temperature of one ml of water by 1 degree Celsius.

Earlier, a calorimeter was used to measure the calorie content of food. That is, a certain amount of food in which water content has evaporated, and this food was put in a vessel surrounded by some water. The container was then sealed, oxygen was supplied in, and the food was ignited.

From the temperature increase of water, the calorie content of food was determined. Today, producers use the “At water indirect system” to find calorie content by adding the calories containing the energy nutrients: protein, carbohydrate, fat and alcohol.

The At water system makes use of the average values of 4 K cal/g for protein, 4 K cal/g for carbohydrate, 9 K cal/g for fat and  7 K cal/g for alcohol that were determined by burning these substances in a calorimeter.

Thus the label on a 45 gram Perk that contains 3 g of protein, 29 g of carbohydrate (22 grams of which are simple sugars) and 12 g of fat would read 230 Calories.

I believe the correct answer would be "It has no energy because it is just sitting there."

I hope this helps! :D

Compound A has molecular formula C5H11Br. When compound A is treated with bromine in the presence of UV light, the major product
damaskus [11]

The compound (A) is 2-bromo-pentane. See attached picture for the chemical diagram.

Explanation:

2-bromo-pentane (A) reacts with bromine (Br₂) under UV light to form 2,2-dibromopentane and HBr. Also 2-bromo-pentane (A) reacts with NaSH to from pentane-2-thiol, which have an asimetric carbon, and NaBr.

You may find the chemical reactions and diagrams of the compounds in the attached picture.

Which diagram shows electrons violating the Pauli exclusion principle?
Neporo4naja [7]
Correct Answer: Option C

Reason:
<span>The </span>Pauli Exclusion Principle<span> states as '<em>in an atom or molecule, no two electrons can have the same four electronic quantum numbers. Further, an orbital can contain a maximum of only two electrons, the two electrons must have opposing spins.</em>'
</span>
Thus, it can be seen that in option C, electrons in last 2 subshell have electrons with same spin, which is a violation of Pauli Exclusion Principle .
