The organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.

<h3>What are organs?</h3>

Organs are a collection of tissues that are closely related and which perform a related function.

The role and function of the organs of the digestive system are as follows:

  • Pancreas - produces pancreatic juice which contain digestive enzymes
  • Liver - produces bile for the emulsification of fat
  • Stomach - serves as a temporary store of food and produces digestive juices
  • Small intestine - functions in food digestion
  • Large Intestine - helps to remove undigested food from the body

Therefore, the organs of the digestive system such as the pancreas, liver, stomach, small intestine, and large intestine help in the digestion of food.

What is the value of 100cm^3 in dm^3​
attashe74 [19]

Answer:

0.1 dm³.

Explanation:

To obtain the value of 100 cm³ in dm³, do the following:

Recall:

1 cm³ = 0.001 dm³

Therefore,

100 cm³ = 100 cm³ × 0.001 dm³ / 1 cm³

100 cm³ = 0.1 dm³

Thus, 100 cm³ is equivalent to 0.1 dm³.

Classify the reactions as endothermic or exothermic.
solong [7]

A - Endothermic. This is because it absorbs heat rather than releases it.

B - Exothermic. It's releasing heat which in turn makes the beaker hot.

C - Endothermic. The Ammonium Chloride is absorbing the heat away from the beaker.

D - Exothermic. To produce nuclear energy, it needs to release heat.

E - Endothermic. The hydrogen and oxygen atoms are absorbing the heat given off from the electric current.

F - Exothermic. It is producing heat or releasing heat.

Exothermic is the losing, release, or production of heat. Endothermic is the exact opposite; it is the storing of heat.

Hope this helps!

How many molecules are in 9.45 moles ? ( NaNO3)
Rzqust [24]

Answer:

There are 5.69*10²⁴ molecules in 9.45 moles.

Explanation:

The mole is defined as the amount of matter that particles have, that is, atoms and elementary entities.

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole and represents a quantity without an associated physical dimension. Avogadro's number applies to any substance.

Then the following rule of three can be applied: if 1 mole contains 6.023 * 10²³ molecules, 9.45 moles, how many molecules will it have?

amount of molecules=\frac{9.45 moles*6.023*10^{23}molecules }{1 mole}

Solving:

amount of molecules= 5.69*10²⁴⁴ molecules

<u><em>There are 5.69*10²⁴ molecules in 9.45 moles.</em></u>

Which of the following is a part of the Kinetic Molecular
GarryVolchara [31]

The Kinetic Molecular Theory exposes, qualitatively and quantitatively, all the laws that the gas field occupies, which explains that molecules in a gas move rapidly.

The Kinetic Molecular Theory describes the behavior of a gas mass, starting from the behavior of the individual molecules.

  • It proposes that the molecules of a gas are in a rapid continuous random movement, which is only altered by the collisions that take place with each other or with the walls of the container.

  • All the collisions produced are elastic, that is, the kinetic energy is not modified or altered by said collision.

Therefore, we can conclude that the Kinetic Molecular Theory describes the behavior of gases, and proposes that gas molecules are in constant chaotic motion, colliding elastically with each other rapidly.
