Why did the potassium permanent crystals in Figure 7.12 on page 197 start to dissolve in water without being stirred or shaken?
The potassium permanganate crystals started to dissolve in water without being stirred or shaken because of the process of diffusion. Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration. The crystals dissolved as their particles spread out and mixed with the water molecules.
Why does soda rise when shaken?
When soda is shaken, carbon dioxide gas in the liquid is released and forms bubbles. These bubbles rise to the surface, carrying the liquid with them and causing the soda to fizz and foam. This process is known as nucleation, where the gas is released rapidly due to the agitation.
Why is my water bottle bubbly?
Your water bottle may be bubbly due to carbonation or gas dissolved in the water, which creates bubbles when the bottle is opened or shaken.
What is the name of a mixture in which large particles may be distributed evenly after being shaken but eventually settle out?
heterogeneous mixture
What happens the particles in a suspension if they are allowed to stand?
Over time, the heavier particles settle to the bottom due to gravity, separating from the liquid phase. This process is known as sedimentation. The liquid above the settled particles is called the supernatant.
How does an insoluble substance form a suspension?
When an insoluble substance is mixed with a liquid, the particles of the substance do not dissolve but instead remain suspended throughout the liquid. The suspension is formed when the particles are small enough to disperse in the liquid but large enough that they do not dissolve. The particles may settle over time due to gravity, requiring the suspension to be shaken or stirred to redisperse them.
Is antibiotic homogenous or heterogenous before it is shaken?
antibiotic is considered as heterogenous because the particles of the antibiotic is scattered to the liquid and it has 2 or more phases, when it is already shaken, we can consider this as homogenous because it will form one phase.

What happens when sodium chloride is added to water or shaken?
Sodium chloride is easily dissolved.
What causes the formation of bubbles in soda?
The formation of bubbles in soda is caused by the release of carbon dioxide gas that is dissolved in the liquid. When the soda is opened or shaken, the pressure is released, causing the gas to escape and form bubbles.
What is a thixotropic liquid?
A thixotropic liquid is a substance that becomes less viscous under stress, such as being stirred or shaken, and returns to its original viscosity when left undisturbed. This property allows the liquid to flow more easily when agitated and then thicken back up once the agitation stops. One common example of a thixotropic liquid is paint.
Why does a flat sealed bottle of fizzy drink when shaken expand the bottle when no new air has got in?
All fizzy drinks contain carbon dioxide dissolved in water (some of it forming carbonic acid). When in this dissolved state the CO2 doesn't take up much space. Shaking the bottle will release the CO2 gas .and one it is no longer dissolved it will tend to take up more space.
Why does beer foam when opened, but not when shaken?
When beer is opened, carbon dioxide gas is released from the liquid, causing foam to form. When beer is shaken, the carbon dioxide gas is dispersed throughout the liquid, preventing foam from forming immediately upon opening.
What is the name of a mixture in which large particles may be distributed evenly after being shaken but evenually settle out?
a suspension

How would you compare an explosive eruption of opening a can of soda that has been shaken?
An explosive eruption is similar to opening a can of soda that has been shaken because, when a can of soda is shaken, the CO2 dissolved in the soda is released and pressure builds up. when the can is opened, the soda shoots out, just as lava shoots out of a volcano during an explosive eruption.
Why is my water bottle bubbly?
Your water bottle may be bubbly due to carbonation or gas dissolved in the water, which creates bubbles when the bottle is opened or shaken.
