Answer:
: The conductivity of electrolyte solutions: (a) 0.1 M NaCl (b) 0.05 M NaCl (c) 0.1 M HgCl2. An electrolyte solution conducts electricity because of the movement of ions in the solution (see above). The larger the concentration of ions, the better the solutions conducts. Weak electrolytes, such as HgCl2, conduct badly because they produce few ions when dissolved (low concentration of ions) and exist mainly in the form of molecules.
Explanation:
Answer: It gets wasted in various forms.
Explanation: The most common way of this energy being wasted is called "waste heat".
Waste heat is the unused heat given to the surrounding environment (in the form of thermal energy) by a heat engine in a thermodynamic process (like a chemical reaction as you said) in which it converts heat to useful work.
Answer:
a
Explanation:
When you blow up the balloon, you are filling it with gas particles. The gas particles move freely within the balloon and may collide with one another, exerting pressure on the inside of the balloon.
Answer:
Saturated
Explanation:
If the sugar sits undissolved at the bottom even after vigorous stirring, the lemonade has dissolved all the sugar it can hold. The lemonade is saturated.
If the lemonade were <em>unsaturated</em>, it could hold more sugar and that at the bottom would continue to dissolve.
The lemonade cannot be <em>supersaturated </em>because, if it were, the solid at the bottom would serve as nuclei on which the excess sugar in the solution could form more crystals.
