Answer:
clf3
Explanation:
it occupied more than 8 valence electrons
Answer:
decomposition is the answer it helped also explanation of it is below this answer
Explanation:
In a decomposition reaction, one reactant breaks down into two or more products. This is the reverse of a synthesis reaction. Replacement reactions occur when elements switch places in compounds
Here is your answer:
Remember that potential energy is the energy a object has when it's NOT moving, and kinetic energy is when a object has energy when it IS moving. So examples of this kid of transformation would be kicking a soccer ball at first the soccer ball has potential energy because it's not moving but it has potential to move then when someone kicks the soccer ball it has kinetic energy because the ball is not moving.
Example one: when the video first begin "the ball had potential energy and when the ball swung and hit it that potential energy turned into kinetic energy."
Example two: As the video moves on and the two pillars crashed down it caused another ball to move, at first the "ball had potential energy because it was not moving then when the ramp went down it caused the ball to gain kinetic energy."
Example three: At the end of the video the ball push down a row of wooden blocks then lead to it hitting a "bowling ball across the finish line even though the ball moved slowly and not far it still came from potential energy into kinetic energy."
Hope this helps!
The answer is: To demonstrate that the liquid is a mixture, the scientist can perform the chromatography.
Mixture: They are formed when two elements or compounds are combined physically and not chemically.
What are the types of mixtures?
- Mixtures are divided into two categories :Homogeneous and heterogeneous.
- Homogeneous mixtures- They have the same composition throughout their mass and there are no visible boundaries between the components of the mixture. Example- Sugar solution, salt solution, alloys, alcohol dissolved in water.
- Heterogeneous mixture- They do not have the same composition throughout there are visible boundaries between the components of the mixture. Example- Milk, sand, and iron fillings, solution of , solution of .
- To demonstrate the the given liquid is a mixture, the scientist can perform Chromatography.
- Chromatography is based on the different rates of adsorption of components of a mixture on a suitable adsorbent.
- When a drop of a mixture of substances is put on a chromatogram paper and the paper is dipped in a solvent, the substance that is more soluble in the solvent rises faster compared to others. And due to this difference in adsorption of different substances, they are separated by the method of chromatography.
- If two spots are seen on a chromatogram that means the liquid is a mixture and if only one spot is visible, that suggests that liquid is a pure liquid.
