Question

Which statements describes h20(l) and h2o2(l)

A) both are mixtures that have different properties

B)both are mixtures that have the same properties

C)both are compounds that have different properties

D)both are compounds that have the same properties

Answer 1

Answer : The correct option is, (C) both are compounds that have different properties.

Explanation :

Molecule : It is the smallest particle in the chemical compound or chemical element that has the same chemical properties of that compound or element.

Compound : It is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass.

The constituents of compound can not be separated into simpler substances by physical methods. They can be separated by chemical methods.

Mixture : It is made up of two or more different substances that are physically combined.

H₂O (l) and H₂O₂ (l) are compounds because they are made from atoms of different elements (hydrogen and oxygen) combined together in a fixed ratio by mass.

Both have different properties.

H₂O (l) and H₂O₂ (l) both are compounds that have different properties.

Hence, the correct option is, (C)

Answer 2

Both H20(l) and H2O2(l) are compounds that have different properties

COMPOUND:

• A compound is any substance formed by the combination of two or more elements bonded together by chemical bonds.

• This suggests that water molecules (H2O) and hydrogen peroxide (H2O2) are both compounds since they are formed from the chemical combination of hydrogen and oxygen elements.

• However, water is made up of two hydrogen atoms and one oxygen atom while hydrogen peroxide is made up of two hydrogen and oxygen atoms.

• This means that the structural arrangement of atoms in both compounds will differ, hence, leading to the difference in properties of both compounds.

Therefore, both H20(l) and H2O2(l) are compounds that have different properties.
