Answer:
What Structures??
Explanation:
Can you please explain the question more
Answer:
Hope this helps :)
Explanation:
1. A physical property is a characteristic of matter that is not associated with a change in its chemical composition.
2. Matter is everything around you. Atoms and compounds are all made of very small parts of matter.
3. Solid, liquid and, gas
4. False
5. Our weight on moon is less than it would be on Earth due to a difference of the strength of gravity on the moon.
6. Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula. Chemical changes are also known as chemical reactions.
Answer:
All of the above.
Explanation:
In positive deviation from Raoult's Law occur when the vapour pressure of components is greater than what is expected value in Raoult's law.
When a solution is non ideal then it shows positive or negative deviation.
Let two solutions A and B to form non- ideal solutions.let the vapour pressure of component A is
and vapour pressure of component B is
.
= Vapour pressure of component A in pure form
= Vapour pressure of component B in pure form
=Mole fraction of component A
=Mole fraction of component B
The interaction between A- B is less than the interaction A- A and B-B interaction.Therefore, the escaping tendency of liquid molecules in mixture is greater than the escaping tendency in pure form.Hence, the vapour pressure of a mixture is greater than the initial value of vapour pressure.
,
Therefore, 
Therefore, the enthalpy of mixing is greater than zero and change in volume is greater than zero.
Hence, option a,b,c and d are true.
Each of the Nitrogen atoms has 2 non bonded valence electrons, meaning that there are 4 pairs total.
