(a)
Interpretation:
Whether distilled water is a compound, a homogenous mixture or a heterogeneous mixture is to be determined.
Concept introduction:
Compounds are formed by the combination of two or more different elements in a fixed ratio. Compounds are represented by using chemical formulas which contain the alphabetical
A mixture consists of a combination of two or more compounds, elements or compound and an element which are physically intermingled. The components of a mixture do not lose their individual identity. The components of a mixture are not
(b)
Interpretation:
Whether gasoline is a compound, a homogenous mixture or a heterogeneous mixture is to be determined.
Concept introduction:
Compounds are formed by the combination of two or more different elements in a fixed ratio. Compounds are represented by using chemical formulas which contain the alphabetical symbols representing the elements they are composed of and numbers which represent the total number of atoms of each element that they are made of.
A mixture consists of a combination of two or more compounds, elements or compound and an element which are physically intermingled. The components of a mixture do not lose their individual identity. The components of a mixture are not chemically bonded to each other. Therefore, the mixture components can be separated using the physical method.
(c)
Interpretation:
Whether beach sand is a compound, a homogenous mixture or a heterogeneous mixture is to be determined.
Concept introduction:
Compounds are formed by the combination of two or more different elements in a fixed ratio. Compounds are represented by using chemical formulas which contain the alphabetical symbols representing the elements they are composed of and numbers which represent the total number of atoms of each element that they are made of.
