Which of the following are homogeneous solutions?

Answer : The homogeneous solutions are, sugar water, air, an unopened soft drink and cement.

Explanation :

Heterogeneous mixtures : It is a mixture that appears non-uniformly throughout the solution and the particle size or shapes are also different.

Homogeneous mixtures : It is a mixture that appears uniformly throughout the solution and the particle size or shapes are not different.

As per question,

Sugar water : It is a homogeneous mixture because its composition is the same throughout the solution.

Air : It is a homogeneous mixture of the gaseous substances of nitrogen, oxygen, and smaller amounts of other substances.

Peanuts and water : It is a heterogeneous mixture because its composition is different throughout the solution.

An unopened soft drink : It is a homogeneous mixture because its composition is the same throughout the solution.

Cement : It is a homogeneous mixture because it is a mixture of calcium compound.

Hence, the homogeneous solutions are, sugar water, air, an unopened soft drink and cement.

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

i do not get it   at all
