In the following description of Fe, some of the properties are physical and some are chemical. Identify which of the properties are chemical. a. Iron has a density of 7.87 grams per cubic centimeter, melts at 1538 o C and boils at 2862 o C .
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.
e. Iron (Fe) is a lustrous silver gray metal.

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: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
