Answer:
Carbohydrates are energy-providing feed components composed of carbon, hydrogen, and oxygen. They should make up about 75 percent of an animal's diet. The energy they provide powers muscular movements. Carbohydrates also produce the body heat that helps keep the animal warm.
Answer: Ok so the MOLE (mol) is a unit of measurement representing the amount of a substance that contains the same number of atoms as there are molecules in exactly 12 grams of carbon-12 (i.e., 6022X1023).
Explanation: And that's how it goes, I hope you understood it well!

TABLE SALT IS A SUBSTANCE.
In chemistry, a substance refers to a matter which has specific composition and specific properties which do not change. A substance can be an element or a compound. A substance typically has a constant composition, which can not be separated by physical methods.
In the question given above, table salt is an example of a chemical substance because, it has a constant specific composition and its components can not be separated by physical methods.
Seawater and sand are not substances, because they have varied compositions and their components can be separated by physical methods.
Hey there!
We can tell from the information we are given that the sum of protons and neutrons is 13, there is 6 protons since it is a carbon atom, and there is no charge which means the number of protons is equal to the number of electrons.
6 + n = 13
n = 7
The number of protons is equal to the number of electrons, so there is 6 electrons.
The isotope 13C has 6 protons, 6 electrons, and 7 neutrons.
Hope this helps!
The balanced chemical reaction is as shown below,
N₂ + 3H₂ --> 2NH₃
The equation shows that every 3 moles of hydrogen, H2, there would be 2 moles of ammonia, NH3, that is going to be formed. Using this concept, we solve for the unknown in this item.
Since we are restricted only of the number of hydrogen, it becomes our limiting reactant.
(6 moles H2) x (2 moles NH3/3 moles H2) = <em>4 moles NH3</em>
Therefore, given enough amount of N2, the amount of NH3 that can be formed out of the 6 moles of H2 is equal to 4 moles.
