Answer:
<em> The answer is </em><u><em>(D) Magnetism</em></u>
The methods separates a homogeneous solution by spinning the solution very fast is magnetism.
Answer:
D. mass has a greater effect than height on gravitational potential energy
Explanation:
The higher up an object is the greater its gravitational potential energy. The larger the distance something falls through the greater the amount of gravitational potential energy the object loses as it falls. ... This is because a tree has more mass, so it needs to be given more gravitational potential energy to reach the same height.More massive objects have greater gravitational potential energy.
I'm assuming you're asking how to test for a starch,
To do so you do this thing called the "Iodine Test"
The potassium iodide aqueous solution will form this complex with starch to form a purplish-blue color.
However, watch out for the pH as hydrolysis of starch could occur to prevent the test from working out-- and the temperature as the greater it is, the less intense the color is
