Answer:
It’s basically molecular nitrogen.
Explanation:
The hypothesis would be that more green bugs would be found than bright red bugs because the green bugs are more camouflaged asunder the green plants than the bright red bugs.
Well, a magnet could DEFINITELY change if it gets exposed to heat, because you could melt the metal and change its shape.
If you hit it hard though, it wouldn't make much of a difference because the magnet is metal, so you'll probably just chip it or leave a dent.
Hope this helps ;)
Answer:
d = 0.9 g/L
Explanation:
Given data:
Number of moles = 1 mol
Volume = 24.2 L
Temperature = 298 K
Pressure = 101.3 Kpa (101.3/101 = 1 atm)
Density of sample = ?
Solution:
PV = nRT (1)
n = number of moles
number of moles = mass/molar mass
n = m/M
Now we will put the n= m/M in equation 1.
PV = m/M RT (2)
d = m/v
PM = m/v RT ( by rearranging the equation 2)
PM = dRT
d = PM/RT
The molar mass of neon is = 20.1798 g/mol
d = 1 atm × 20.1798 g/mol / 0.0821 atm. L/mol.K × 273K
d = 20.1798 g/22.413 L
d = 0.9 g/L
6.02 times 10 to the 23 power, which is Avogadros number
