Suggest 2 reasons why the noble gases become less ideal in their behaviour down the group from helium to xenon.
Elenna [48]
Reason1: electrons on farther layers become free easyer
2nd reason: volume of atoms grows (from Helium to Xeon) so instead  of boyle-mariot law equation (PV=vRT) is  more accurate to use van der walls equations that adds to the boyle-mariot equation the volume occupied by the atoms of the gas to the volume of the space between the atoms P(Vm-b)=vRT

Photosynthesis uses 660-nm light to convert co2 and h2o into glucose and o2. calculate the frequency of this light.
Allushta [10]
The unit expressed in 660 nm of light represents the wavelength of light. If you want to determine the frequency, you use the speed of light to relate the two. The formula is:

c = λν
where
λ is the wavelength
ν is the frequency
c is the speed of light = 3×10⁸ m


Apply SI units:
(3×10⁸ m) = (660×10⁻⁹ m)(ν)
Solving for ν,
<em>ν = 4.55×10¹⁴ s⁻¹</em>

The volume of a sample of <img src="https://tex.z-dn.net/?f=P_b" id="TexFormula1" title="P_b" alt="P_b" align="absmiddle" class=
murzikaleks [220]

Answer : The mass of sample is, 267.5 grams.

Explanation :

Density : It is defined as the mass of a substance contained per unit volume.

Formula used :

Density=\frac{Mass}{Volume}

Given:

Volume of Pb = 23.57cm^3

Density of Pb = 11.35g/cm^3

Now put all the given values in the above formula, we get the mass of Pb.

11.35g/cm^3=\frac{Mass}{23.57cm^3}

Mass=267.5195g=267.5g

Therefore, the mass of sample is, 267.5 grams.
