<span>Like dissolves like and unlike repels like. This applies to the polarity of the solutions. Polar dissolves polar and non-polar does not mix with polar solutions. In this case, the polar substance that can mix with water. Sugar and salt can be dissolved through agitation. Oil which is nonpolar is immiscible in water. Hence answer is D. </span>
Answer: Many elements produce colors in the flame when heated.
Explanation:
The origin of this phenomenon lies in the arrangement, or “configuration” of the electrons in the atoms of the different elements In the flame test, if this energy has the form of visible light, the flame will produce a color characteristic of the element.
Answer:
A
Explanation:
is most likely to be formed.
Answer:
<u>Homogeneous mixture:</u>
- These are called solutions.
- It has a uniform composition.
- It has only one phase.
- It cannot be separated physically.
- The particles appear smaller in size.
- These are pure substances.
- These are not visible easily visible to the naked eye and also through a microscope.
- Examples include milk, gasoline, sugar solution, corn oil, fog, etc.
<u>Heterogeneous mixture:</u>
- These are called suspensions/colloids.
- It has a non-uniform composition.
- There are two or more phases.
- It can be separated physically.
- The particles are either smaller or larger in size.
- These are not pure substances.
- These are easily visible to the naked eye and also through a microscope
- Examples are- a mixture of mud & water, beach sand, vinegar, air cloud, etc.
