<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.

Answer:
Lots of things here
Explanation:
Ammonia structure is written as NH3
carbon monoxide is CO
make bonds between O2, so there is 2 oxygen atoms per group,
anything with multiple elements bonded is a compound, thus your answer for carnon monoxide isnt correct, it should be CO for written and it is a compound. Fix your formula for ammonia and also max a bond between those two oxygens because it is O2 not O,
Your structure for SO2 is improper aswell, there are only 3 elements in this molecule, and usually the one out in front of the molecule is the central atom (except hydrogen). So it would go O-S-O for the structure, with only two bonding groups.
Answer:
True
Explanation:
Pure substances are made of the same material throughout and have the same properties throughout.

Examples of Gases
A gas does not have a defined shape or volume, so it can expand to fill any size or shape of a container. Particles in gases are widely separated, compared to those in liquids and solids.
