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: The mole fraction of neon in the final mixture is 0.6
Explanation:
According to Dalton's law, the total pressure is the sum of individual pressures.
Given : =total pressure of gases = 5.0 atm
= partial pressure of argon = 2.0 atm
= partial pressure of Neon = ? atm
According to Raoults law, the partial pressure of a gas is equal to its mole fraction mulitiplied by the total pressure.
= mole fraction of Neon
Thus mole fraction of neon in the final mixture is 0.6
