Answer:

Explanation:
Hello,
In this case, given that the same temperature and pressure is given for all the gases, we can notice that 16.0 mL are related with two moles of carbon monoxide by means of the Avogadro's law which allows us to understand the volume-moles relationship as a directly proportional relationship. In such a way, since in the chemical reaction:

We notice two moles of carbon monoxide yield two moles of carbon dioxide, therefore we have the relationship:

Thus, solving for the yielded volume of carbon dioxide we obtain:

Best regards.
The number of atoms that are in 0.32 g of copper are
3.01 x10^21 atoms
<u><em>calculation</em></u>
<u><em> </em></u>Step 1: find the number of moles of Copper
moles = mass/molar mass
= 0.32 g /63.5 g/mol=0.005 moles
Step 2: use the Avogadro's constant to determine the number of atom
in 0.005 moles of Cu
that is according to Avogadro's law 1 mole =6.02 x10^23 atoms
0.005 moles=? atoms
by cross multiplication
= (0.005 moles x 6.02 x10^23 atoms) / 1 mole= 3.01 x10 ^21 atoms
I don’t know if I’m right I’m taking a guess but isn’t it because energy comes from the sun and we can’t change the sun
Answer is: nucleus of Cd is 1.26 times greater.
The Nuclear radius formula or radius of nucleus formula: R = R₀ · ∛A.
R is nuclear radius.
R₀ is empirical constant, R₀ = 1.2 10⁻¹⁵ m.
A is number of nucleon.
R(Fe) = 1.2·10⁻¹⁵ m · ∛56.
R(Fe) = 4.59·10⁻¹⁵ m.
R(Cd) = 1.2·10⁻¹⁵ m · ∛112.
R(Cd) = 5.78·10⁻¹⁵ m.
R(Cd) / R(Fe) = 5.78·10⁻¹⁵ m / 4.59·10⁻¹⁵ m.
R(Cd) / R(Fe) = 1.26.
