Which of the following statements about a compound is/are TRUE?
Which of the following statements about a compound is/are TRUE?
The correct options are
A It is a pure substance.
B Its constituents are combined chemically.
C Its constituents do not retain their individual properties.
In a compound, the constituent substances are combined chemically in a fixed ratio and cannot be separated by physical methods. Irrespective of the source or origin, the ratio of the masses of the combining elements remain constant, for example, water sourced from tap or rain has the same chemical formula, H2O.
Pure substances are defined as substances that are made of only one type of atom or only one type of molecule (a group of atoms bonded together). We know compounds are the physical aggregation of one type of molecules, hence compounds are pure substances.
