Answer:
Explanation:
Hello!
In this case, since the reaction may be assumed in chemical equilibrium, we can write up the rate law as shown below:
However, since the rate of reaction at equilibrium is zero, due to the fact that the concentrations remains the same, we can write:
Which can be also written as:
Then, we solve for the concentration of NO to obtain:
Best regards!
Answer:
<em> A solution </em><em>which </em><em>can dissolve no more solute at a given temperature </em>is called saturated solution.
Explanation:
Solutions can be classified as following on the basis of solubility of solutes.
(i) Unsaturated Solutions:
These are solutions which has the ability to dissolve more solute in given amount of solvent at given temperature. Hence, when solutes are added in such solutions they dissolve completely.
(ii) Saturated Solutions:
The solutions which when aded with solute fails to dissolve it are called saturated solutions. These solutions are already saturated with dissolved solutes and don't have the ability to dissolve more. Hence, when solutes are added to saturated solutions they settle down or precipitate out at the bottom.
(iii) Supersaturated Solutions:
These solutions are formed when the saturated solutions are heated. After heating the solubility of solute increases and hence, more solute can dissolve. And when supersaturated solutions are allowed to cool the extra dissolved solutes starts precipitating out.
Atoms form a new substance by bonding with different atoms.
For example, hydrogen atoms and oxygen atoms bond to form H2O as per this equation:
2H2 + O2 ---> 2 H2O
To understand how to hydrogen and oxygen atoms form water you can write that as:
2 H - H + O - O ---> 2 H - O - H
Each hypen represent a chemical bond.
What is happening is that the H - H atoms and the O - O separate and bond with different atoms: H bonds to O which in turn bonds to other H.
Also, you have to know that chemical bonds are the result of interaction between the electrons of the valence shell of electrons of each atom. This is, valence electrons from O interact with valence electrons of H to form the bond H - O.
The interaction may be in different ways depending on the properties of the atoms: the kind of bonds known are metallic, ionic and covalent.
