Answer:Vrms is 149.7266 m/sec
Explanation:The root means square velocity of a gas can be calculated as follows:
Vrms =

where:
R is the ideal gas constant = 8.3145
T is absolute temperature = -55 + 273 = 118 degrees kelvin
M is the molar mass of the gas = 131.293 grams = 0.131293 kg
Substituting with these givens in the above equation, we would find that the Vrms is 149.7266 m/sec
Hope this helps :)
Chemical bonds are broken to supply us with energy. Without bonds, and our ability to break them, the food we eat would not supply us with energy.
Answer:
Molality is 0.40 m
Explanation:
Molality is a sort of concentration that indicates the moles of solute dissolved in 1kg of solvent.
To determine molality we need the moles of solute, and the mass of solvent in kg so:
We convert the mass of solvent from g to kg:
740 g . 1kg/1000g = 0.740 kg
We know the moles, so we can determine molality
Molality (mol/kg) = 0.295 mol/ 0.740kg = 0.40 m
<span>I believe the answer is letter c. haf energy is carried by the electric field hand half is carried by a magnetic field. the movements are in travelling in a perpendicular movement, a kind of x and y axis that creates oscillation producing electric fields. The effect can make magnet out of electricity.</span>
Answer:
Yes
The simple answer is yes. Almost everything has atoms and molecules consisting in it. The answer is yes. Hope it helps!
