Any change in which the composition of material does not change that is it retains its identity but changes its state or form is known as a physical change.
The properties of metal to draw them into wires is known as ductility. When a copper is drawn into wire the only change that occurs is change in its shape and size no change will take place into its composition that is the wires are still possessing the properties of copper metal. Thus, a physical change takes place when copper is drawn into wire.
Answer : The correct option is, 13.7 mole
Solution : Given,
Moles of = 27.4 moles
The given balanced chemical reaction is,
From the balanced chemical reaction, we conclude that
As, 2 moles of react with 1 moles of
So, 27.4 moles of react with moles of
Therefore, the number of moles of oxygen required are, 13.7 moles
Lipids are in a class called fat or lipid solvents.
