I believe the change of state shown in the model is deposition.
Deposition is a process in which gases change phase and turns directly in solids without passing through the liquid phase. It is the opposite of sublimation.
One of the major difference between gases and solids is the distance between molecules; in gases the inter molecular spaces are large, while in solid they are very small, making solids be the most dense, with closely packed molecules. This is evident in the diagram, the phase changed from gases to solids.
Answer:
The sum of the molar masses of each isotope of the element.
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
Answer:
And this expansion makes ice is less dense than liquid water, which means that ice floats! ... If you drop a piece of solid iron into liquid or molten iron, it will sink before it melts.
Explanation:
