Both of you are overlooking a pretty big component of the question...the Group I cation isn't being dissociated into water. We're testing the solubility of the cation when mixed with HCl. And this IS a legitimate question, seeing as our lab manual is the one asking.
<span>By the way, the answer you're looking for is "Because Group I cations have insoluble chlorides". </span>
<span>"In order...to distinguish cation Group I, one adds HCl to a sample. If a Group I cation is present in the sample, a precipitate will form." </span>
This is called adaptation. An example would be a polar bear with white fur. They have this to be more efficent hunters, as they use it as a type of camouflage in order to sneak up on prey. Brown bear use this in the same way but their environment requires them to be brown in order to blend in beter with trees. So basicly adaptation
Answer:
The term temperature refers to the average amount of heat or the motion energy of particles in a substance. It measures the hotness and coldness of a substance. If an object has particles that move very fast, then it has a high temperature.
Temperature is different from the term thermal energy. Thermal energy is the total motion energy of particles in a substance. The movement of particles is always dependent on their number. If an object contains many particles, then it has greater thermal energy.
On the other hand, Heat is the energy that is involved in the movement of particles between objects that have different temperatures, particularly from an object with a high temperature to an object with a low temperature.
