Physical changes are changes affecting the form of a chemical substance, but not it's chemical composition.
The statement "According to Le Châtelier's principle, an increase in temperature will shift the equilibrium position toward the products in an endothermic reaction" is definitely true.
<h3>What is Le Châtelier's principle?</h3>
Le Châtelier's principle may be defined as transformations in the temperature, pressure, volume, or concentration of a system that will lead to observable and conflicting changes in the strategy in order to accomplish a refreshed equilibrium state.
According to Le Châtelier's principle, an increase in temperature generates the equilibrium to move in the direction of the product of the endothermic reaction, and the decrease in the temperature rationales the equilibrium to move in the direction of the product of the exothermic reaction.
Therefore, it is well described above.

Answer:
Let, X be the oxidation state of Cr in K
2
Cr
2
O
7
.
2(+1)+2X+7(−2)=0
2+2X−14=0
2X=12
X=+6
Hence, the oxidation state of Cr in K
2
Cr

is +6.
When the water level of a stream or river exceeds its natural banks, it has reached its D. FLOOD STAGE
Flood stage is an established gauge height for a given location above which a rise in water surface level begins to create a hazard to live, property, or commerce. The issuance of flood warnings are the result of flood stage.
