Answer: The given reaction is a double displacement reaction.
Explanation:
A chemical reaction in which two different compounds chemically react with each other by switching places of both positive and negative ions is known as a double displacement reaction.
For example, 
Here, both 
and 
ions switched places. Also, both 
and 
ions switched places.
Therefore, we can conclude that the given reaction is a double displacement reaction.
Answer:
H₂: 0.48, N₂: 0.43; Ar: 0.09
Explanation:
First of all, sum all the pressures to know the total pressure in the mixture.
434 Torr + 389.9 Torr + 77.9 Torr = 901.8 Torr
Mole fraction = Pressure gas / Total Pressure
Mole Fraction H₂: 434 Torr /901.8 Torr = 0.48
Mole Fraction N₂: 389.9 /901.8 Torr =0.43
Mole Fraction Ar: 77.9 /901.8 Torr = 0.09
Remember: <u>SUM OF MOLE FRACTION = 1</u>
I suppose because of the fact that the relative humidity is taking away your heat and making you feel cool, I think that you would feel cooler than someone who was dry.
An electron has a negative charge of one
An neutron has no charge (hence, neutral)
An proton has a positive charge of one

Answer:
The answer is
D. Main sequence
Explanation:
Main sequence stars can be between one thousand times dimmer and one million times brighter than the Sun.
What is main sequence stars?
A main sequence star is any star that is fusing hydrogen in its core and has a stable balance of outward pressure from core nuclear fusion and gravitational forces pushing inward.
