Answer:
The temperature of the molecule will be increased by a factor of 9
Explanation:
The relationship between the temperature and the rms speed of a gas is given by
Vrms=√(3RT/MM)
Where R = Universal gas constant
T = Absolute temperature of the gas in kelvin
MM = Molar mass of the gas
Since from the question, only the rms speed and the temperature are said to change, the term 3R/MM can be represented by a constant k. The relationship then becomes Vrms=√kT
At the intitial speed, temperature = T1
Vrms=√(kT1 ) (1)
When the speed is increased by a factor of 3, the relationship becomes
(3V)rms=√(kT2 ) (2)
Dividing equation (2) by equation (1)
(3V)rms/Vrms =√(kT2 )/√(kT1 )
3=√(T2/T1 )
T2/T1 =9
The temperature of the molecule will be increased by a factor of 9
The correct name for the N3- ion is a nitride ion.
If you look at the Periodic Table of Elements, all three of those qualities increase as you move from left to right and bottom to top, so that they are max at the top right corner.
In your question all three qualities are low, so the element is likely in the bottom left portion of the table.

Answer:
0.18 Moles
Explanation:
first you need to convert the 5.4g to moles using molar mass
)
once you have that done you can use the molarity equation to get the answer
now you need to round to the correct sig fig which will give you the correct answer of 0.18moles
