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.

If you had 2.50 moles of anything, how many of those things would you have?
Wittaler [7]

Answer:

1.51 x 10²⁴ things

Explanation:

According to Avogadro's Constant.

1 mole of any substance, constains 6.02×10²³ particles of that subtance.

From the question,

If we have 2.50 moles of anything,

1 mole of anything ⇒ 6.02×10²³ things

2.50 moles of anything ⇒ y things

solving for y

y = (2.50× 6.02×10²³)/1

y = 15.05×10²³

y = 1.505×10²⁴

y ≈ 1.51×10²⁴

_AI + _HCI —&gt; _H2 + _AlCl3
SOVA2 [1]

Hey there!

Al + HCl → H₂ + AlCl₃

Balance Cl.

1 on the left, 3 on the right. Add a coefficient of 3 in front of HCl.

Al + 3HCl → H₂ + AlCl₃

Balance H.

3 on the left, 2 on the right. We have to start by multiplying everything else by 2.

2Al + 3HCl → 2H₂ + 2AlCl₃

Now we have 2 on the right and 4 on the left. Change the coefficient in front of HCl from 3 to 4.

2Al + 4HCl → 2H₂ + 2AlCl₃

Now, for Cl, we have 4 on the left and 6 on the right. Change the coefficient in front of HCl again from 4 to 6.

2Al + 6HCl → 2H₂ + 2AlCl₃

Now, our H is unbalanced again. 6 on the left, 4 on the right. Change the coefficient in front of H₂ from 2 to 3.

2Al + 6HCl → 3H₂ + 2AlCl₃  

Balance Al.

2 on the left, 2 on the right. Already balanced.

Here is our final balanced equation:

2Al + 6HCl → 3H₂ + 2AlCl₃  

Hope this helps!

marusya05 [52]

Answer: A. Gamma Ray

Explanation:

X-ray scans can diagnose possibly life-threatening conditions such as blocked blood vessels, bone cancer, and infections. However, x-rays produce ionizing radiation—a form of radiation that has the potential to harm living tissue. However, the risk of developing cancer from radiation exposure is generally small.
