The best answer here is B , i.e. the components of a homogenous mixture are evenly distributed
This means the constituents are mixed uniformly.
In a heterogeneous mixture, the constituents are not mixed uniformly.
Some good examples of a homogeneous mixture are:
1. Sugar solution
2. Soda
3. Water
5. soft drinks
6. Air
7. Vinegar
8. Brine
Some examples of a heterogeneous mixture are:
1. Blood
2. Milk
3.Water and oil
4. Water and sand
5. Soil
6. Hollandaise sauce
8. smog

Answer:
A chemical change is required to separate the elements present in it.
Explanation:
The only true statement from the choices given is that water as a pure substance requires a chemical change to separate the elements present in it.
Water is a molecule consist of two atoms of hydrogen and one atom of oxygen.
- The atoms are covalently bonded together.
- A chemical process, the electrolysis of water is often used to separate the atoms of a water.
- Physical changes cannot be used to separate the atoms of water.
- Water is a compound which consists of two elements.
Therefore, we see that only the first choice satisfies this problem.
