Hello Mate!Well, there are
many definitions and descriptions of isolated systems, and
here are some of them:
1.
It can be a physical system which is located very very far from all other systems, so there is absolutely no interaction between them, thus making it isolated.
2.
It can be a thermodynamic system with rigid walls, which prevents mass and energy to pass through.
I Hope my answer has come to your Help. Thank you for posting your question here in
We hope to answer more of your questions and inquiries soon.
Have a nice day ahead! :)

C = Carbon
If you look in a periodic table and see the mass number for carbon. Its estimated around 12.
I believe it's between 1-2 moles.
All you have to do is 13/12 which will give yoy the estimated answer which is around 1.08 mole.
Answer:
2.5 moles of N₂ and 7.5 moles of H₂ entered the reaction
Explanation:
In reaction:
N₂(g) + 3 H₂(g) → 2 NH₃(g)
You can see that the stoichiometry of the reaction (that is, the relationship between the amount of reagents and products in a chemical reaction) requires the following amounts of reagents and are produced:
- N₂: 1 mole
- H₂: 3 moles
- NH₃: 2 moles
The following three rules can apply:
- If 2 moles of NH₃ are produced from 1 mole of N₂ by stoichiometry of the reaction, 5 moles of NH₃ from how many moles of N₂ are produced?
moles of N₂= 2.5
- If 2 moles of NH₃ are produced from 3 moles of H₂ by stoichiometry of the reaction, 5 moles of NH₃ from how many moles of H₂ are produced?
moles of H₂= 7.5
<u><em>2.5 moles of N₂ and 7.5 moles of H₂ entered the reaction</em></u>
Electromagnet is a type of magnet which is produced by passing electric current through a magnetic material such as iron. Here electric energy is converted to magnetic energy. The magnetic material is coiled with wire through which electric current is passed. Increasing the number of coils and increasing the strength of the current increases the strength of the electromagnet. However, the electromagnet loses its magnetic properties when the current flow is switched off.
(Answer) (1) Increase the number of coils and increase the strength of the current.
