Can you post the picture of the structure of pyrollium. because my teacher has taught us to determine if it is aromatic cyclic or conjugated by looking at the structure of the molecule.
Answer:
b. Iron forms complexes with molecular oxygen in proteins like hemoglobin and myoglobin
c. Iron rusts readily in moist air.
d. Iron powder dissolves in an acidic solution with the evolution of a gas.
Explanation:
The chemical properties of an element is the property of the element that is being noticed during or after a chemical reaction. The chemical properties can only be observed when the chemical composition of the compound is about to be changed or is changed. From the question the propeties that are chemical are:
Iron forms complexes with molecular oxygen in proteins like hemoglobin and myoglobin
Iron rusts readily in moist air.
Iron powder dissolves in an acidic solution with the evolution of a gas.
The remaining properties are physical properties (they can be measured and shows the physical state)
If organisms cannot adapt to the changes in their ecosystem, they may move to another location. If they will not move, the species may become threatened, endangered or extinct.
