<span>What did you observe?
When the mixture of Jell-O is shined with the light you observe that the mixture becomes opaque or misty.
In the other two glasses the mixture remains clear
The Jell-O mixture dispereses the light while the other two glasses let the light pass through them.
What is the Tyndall effect?
The Tyndall effect is the dispersion of light by colloid particles. This happens becasue colloid particles present in the mixture are bigger than solvated particles.
Colloid particles are so small that they cannot be in the mixture, but are big enough to disperse the light.
Which glass displayed the Tyndall effect?
The glass with the Jell-O displayed the Tyndall effect.
What does that tell you about the substance in the glass?
The mixture of this glass is a colloid, because they are the only mixtures that may look clear but becomes misty when the light passes trhough them.
Which glass represents a pure substance?
Only the glass with pure water represents a pure substance, one of the glasses that did not disperse the light.
Which glass represents a solution?
The other glass that did not disperse the light is a solution.
Pure substances and solutions do not disperese water. Diluted coloids look clear but disperse light.

In the KLMN electronic configuration style of writing K denotes the first shell which can hold up to two electrons, L denotes the second shell which can hold up to eight (2 + 6) or 8 electrons, M denotes the third shell which can hold up to eight (2 + 6 + 10) or 18 electrons etc.
The KLMN style of writing only indicates the number of electrons in each principal quantum number, however the spdf electronic configuration style of writing subdivides each shell into its subshells.
For instance the 3rd principal quantum number has s,p and d subshells, wherein s, p and d orbitals can have a maximum of 2, 6 and 10 electrons respectively.
Answer:
B, C, and D
Explanation:
A is the only one in which two components are being combined. The point is to separate the mixture, so that is the only one that would not apply.
Answer:
The rapid movement of excess charge from one place to another is an <em>electric discharge.</em>
Explanation:
A material in which electrons <em>CANNOT</em> move easily from place to place is an insulator. A material in which electrons <em>CAN </em>move easily from place to place is a conductor.
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. This is referred to as interia . If an unbalanced force such as another vehilce hits another, than a persons air bag will then be active . Because when a car is in motion at a constant speed, that’s what will happen when an unbalanced force acts apon it .
