The given equation is is
this is not balanced
The balanced equation will be:
Now as per it if we are using eight moles of HNO3 we are getting two moles of NO
so for each mole of NO we have to take four moles of HNO3
Hence the mole ratio of NO produced to HNO3 reacted will be = 1:4

Answer:
In classical theories of gravitation, the changes in a gravitational field propagate. A change in the distribution of energy and momentum of matter results in subsequent alteration, at a distance, of the gravitational field which it produces.
Explanation:
Hey there!:
the chemical reaction between 2-iodoctane and sodium nitrite is as follows:
Answer:
Bonds are broken and new bonds are formed during chemical reactions only.
Explanation:
- A physical change in a substance doesn't change what the substance is.
- In a chemical change where there is a chemical reaction, a new substance is formed and energy is either given off or absorbed.
- Physical changes can be reversed, chemical changes cannot be reversed with the substance changed back without extraordinary means, if at all. For example, a cup of water can be frozen when cooled and then can be returned to a liquid form when heated.
So, the right choice is:
Bonds are broken and new bonds are formed during chemical reactions only.
