Hm, this could be more than one option, but gaining electrons makes a negative charge, so
If atoms of a halogen nonmetal (Group 17) gains one electron, the atoms the have "a negative one charge".
Answer:
If you meant moles then 3.13144 x 10^24
5.2 mol times 6.022 x 10^23 atoms / mol
Explanation:
The complete question is:
To liquify a fixed amount of gas, one may 1. increase the temperature while decreasing the pressure. 2. increase the volume while increasing the pressure. 3. decrease the temperature while decreasing the pressure. 4. decrease the temperature while increasing the pressure. 5. decrease the volume while decreasing the pressure.
Answer:
4. decrease the temperature while increasing the pressure
Explanation:
The thermodynamics explains the sate of a substance (generally a gas or a liquid), which is its characteristics: temperature, pressure, volume, enthalpy, etc. When they changed, the state changes. Some of these changes may induce a physical change.
A gas has distant and agitated molecules, thus, the pressure is low and the temperature is higher, and a liquid has more close and less agitated molecules, so with higher pressure and low temperature.
Thus, to liquefy a fixed amount of has one may decrease the temperature while increasing the pressure.
the change in heat associated with a chemical reaction or process the stability of a substance over a wide range of temperatures
Explanation:
A calorimeter is a device used to monitor the change in heat associated with a chemical reaction. It is also used to process the stability of a substance over a wide range of temperatures.
- Calorimeters are specially designed devices that are used to track heat changes accompanying any form of reaction.
- The are designed no to lose any amount of heat to the environment.
- Heat loss by radiation, conduction and convection have factored into the designing of a calorimeter.
- Heat loss in a calorimeter is gained by another body inside of it with no loss to the surroundings.

Answer is: (4) The frequency of collisions between atoms increases.
The average kinetic energy of molecules depends on the temperature.
As temperature increases, molecules gain more energy from surrounding and move faster and have more collisions.
Kinetic energy (standard unit is the joule J) depends on speed of the molecule.
Charles' Law (The Temperature-Volume Law) - the volume of a given amount of gas held at constant pressure is directly proportional to the Kelvin temperature:
V₁/T₁ = V₂/T₂.
When temperature goes up, the volume also goes up.
