To determine:Match the following physical and chemical properties with potassium chloride, KCl, used in salt substitute, or butane, C4H10 used in lighters:
- Melts at -138 oC
- Burns vigorously in air
- Melts at 770oC
- Contains ionic bonds
- Is a gas at room temperature
Answer to Problem 11.39UTC
Solution:
- Melts at -138 oC:Physical property of butane
- Burns vigorously in air: Chemical property of butane
- Melts at 770 oC: Physical property of KCl
- Contains ionic bonds: Chemical property of KCl
- Is a gas at room temperature: Physical property of butane
Explanation of Solution
Physical property is the property that can be observed or measured without changing the element, like color, shape and volume. On the other hand, chemical properties are observed by changing the chemical identity of substance.
- Melts at -138 oC: Melting is change of state from solid to liquid. No chemical identity of the substance is changed.So, it is a physical property. Butane has a melting point -138 oC. So, this is a physical property of butane.
- Burns vigorously in air: Butane is a carbon containing compound, C4H10.When come in contact with air (O2), it burns to give CO2and H2O. Chemical identity of butane is changed. So, it is a chemical property.
- Melts at 770 oC: Melting is change of state from solid to liquid. At 770 oC, KCl melts. So, this is physical property of KCl.
- Contains ionic bonds: Ionic bonds are formed when a metal forming positive ion and nonmetal forming negative ion interact together. In case of KCl, potassium (K) is metal and Cl is nonmetal. So ionic bond will be form in KCl.Butane has carbon, hydrogen. Both are nonmetal, so ionic bond is not there.
- Is a gas at room temperature: Gas represents the physical state of a substance.At room temperature, butane is a gas and KCl is solid. So, this represents physical property of butane.
The properties are assigned physical and chemical on basis of their observable properties and where there is any change in the chemical identity of the substance. Melting is a physical property and -138 oC and 770 oC represent physical property of butane and KCl. Combustion and formation of ionic bonds are chemical properties.
