Answer :
The substance is in the gas phase only in region → 5
The substance is in both the liquid and the solid phase in region → 2
The substance is in only the liquid phase in region → 3
The melting point is the temperature at region → 2
The boiling point is the temperature at region → 4
Explanation :
Six phases of substance:
- Melting or fusion : In this process the phase changes from solid state to liquid state at constant temperature.
- Freezing : In this process the phase changes from liquid state to solid state at constant temperature.
- Evaporation : In this process the phase changes from liquid state to gaseous state at constant temperature.
- Condensation : In this process the phase changes from gaseous state to liquid state at constant temperature.
- Sublimation : In this process the phase changes from solid state to gaseous state without passing through the liquid state at constant temperature.
- Deposition : In this process the phase changes from gaseous state to solid state without passing through the liquid state at constant temperature.
Answer:
It provides the electrons that "make" electricity and it contains the electrons that are involved in molecular bond formation.
Answer : The volume of water added are, 15 mL
Explanation :
Formula used :
where,
are the initial molarity and volume of HCl.
are the final molarity and volume of water.
We are given:
Putting values in above equation, we get:
Hence, the volume of water added are, 15 mL
Answer:
Nitrogen and Arsenic
Explanation:
Since Phosphorous and Arsenic both are Nitrogen group elements i.e. Group(Va)
