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)
Answer:
Os óxidos são compostos binários formados pela reação do oxigênio com outros elementos. O oxigênio é altamente reativo por natureza. Eles reagem com metais e não metais para formar óxidos.
Os óxidos normalmente reagem com ácidos ou bases, às vezes ambos. ... Os metais tendem a formar óxidos básicos, os não metais tendem a formar óxidos ácidos e os óxidos anfotéricos são formados por elementos próximos à fronteira entre metais e não metais (metaloides).
