24.25 moles of NO can be produced using 97 moles of HNO3.
<h3>What is balanced chemical equation?</h3>
Equal numbers of atoms from various elements are present in both the reactants and the products in balanced chemical equations. Varied elements' atom counts in the reactants and products of unbalanced chemical equations are different.
3 Cu + 8HNO3 g → 3 Cu(NO3)2 + 2 NO + 4 H2O
The number of moles consumed can be calculated using comparing with coefficients in the balanced reaction .
So , from above eq we get that 8 moles of HNO3 are consumed to make 2 moles of NO.
⇒ 8 HNO3⇔2 NO
⇒ 1 HNO3⇔ 1/4 NO
This means that for each mole of HNO3 produces 1/4 moles of NO.
So , for 97 moles of HNO3 , 
moles of NO can be made,
So, total moles of NO made are 24.25 moles.

Answer:
a) (CH3)3N
b) 4-methylpyridine
Explanation:
Let us bear in mind that the basicity of amines depend on;
1) the availability of the lone pair
2) the stability of the conjugate acid of the amine.
In the gaseous phase, the basicity of the amine strictly depends on the availability of the lone pair. The tertiary amine is better able to accept a proton in the gaseous phase since it is surrounded by three methyl groups having an electron pushing effect thereby reinforcing the lone pair on the nitrogen. This order is reversed in solution due to solvation.
Here again, the electron donation to the nitrogen bearing the lone pair is important. The 4-methylpyridine is more basic than 2-methylpyridine to BMe3 due to steric hindrance that hinders the bonding of 2-methylpyridine to BMe3.
Answer:
<u>Homogeneous mixture:</u>
- These are called solutions.
- It has a uniform composition.
- It has only one phase.
- It cannot be separated physically.
- The particles appear smaller in size.
- These are pure substances.
- These are not visible easily visible to the naked eye and also through a microscope.
- Examples include milk, gasoline, sugar solution, corn oil, fog, etc.
<u>Heterogeneous mixture:</u>
- These are called suspensions/colloids.
- It has a non-uniform composition.
- There are two or more phases.
- It can be separated physically.
- The particles are either smaller or larger in size.
- These are not pure substances.
- These are easily visible to the naked eye and also through a microscope
- Examples are- a mixture of mud & water, beach sand, vinegar, air cloud, etc.
If the magnetic lines of force intersected each other, then that would violate the laws of physics.
If the lines intersected, then at the point of
intersections there would be two directions of magnetic field force, and this cannot defy the laws of physics, so therefore it does not happen.
A good example of this would be if you had a
compass and you tried to use it to view the field direction. If you had two lines of force
intersecting, then the compass would have to
point in both directions, and that can't happen both theoretically and through observation.
An event like that would generate a monopole, which is an impossible, theoretical magnetic event.
