<h2>Mass preservation.</h2>
Explanation:
- Mass of the system must remain the same over time, as the system's mass cannot alter according to the law of preservation of mass for any closed system.
Landolt Experiment -
- Landolt was German chemist, He demonstrated the law of preservation of mass experimentally by utilizing H- glass tube filled with silver nitrate in appendage A and HCl corrosive in appendage B.
- The reactants were blended and a white accelerate of Silver chloride was shaped alongside nitric corrosive. The tube is weighed once more.
Uno:
El dióxido de Carson (CO2)
Answer:
Explanation:
to put this plainly after putting strong electrolytes in water they dissolve to nothing but ions they give you an example and definition of a strong electrolyte I suggest you read those and see if you come up with what I gave you they also tell you that not all strong electrolytes dissolve as strongly as others that are in the example.
Answer:
Semiconductors are poor conductors at low temperatures, but their resistance decreases with increasing temperature.
Explanation:
A semiconductor can be defined as a crystalline solid substance that has its conductivity lying between that of a metal and an insulator, due to the effects of temperature or an addition of an impurity. Semiconductors are classified into two main categories;
1. Extrinsic semiconductor.
2. Intrinsic semiconductor.
The statement which best describes the electrical conductivity of metals and semiconductors is that semiconductors are poor conductors at low temperatures, but their resistance decreases with increasing temperature.
This ultimately implies that, semiconductors are typically an insulator (poor conductor) at low temperatures and a good conductor at high temperatures.
Additionally, conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction.
