CuO (s) + CO (g) → Cu (s) + CO₂ (g)
Explanation:
The balanced chemical reaction between copper (II) oxide and carbon monoxide is producing cooper and carbon dioxide:
CuO (s) + CO (g) → Cu (s) + CO₂ (g)
where:
(s) - solid
(g) - gas
To balance the chemical equation the number of atoms of each element entering the reaction have to be equal to the number of atoms of each
element leaving the reaction, in order to conserve the mass.

Answer:
Mole fraction of solute is 0.0462
Explanation:
To solve this we use the colligative property of lowering vapor pressure.
First of all, we search for vapor pressure of pure water at 25°C = 23.8 Torr
Now, we convert the Torr to mmHg. Ratio is 1:1, so 23.8 Torr is 23.8 mmHg.
Formula for lowering vapor pressure is:
ΔP = P° . Xm
Where ΔP = P' (Vapor pressure of solution) - P° (Vapor pressure of pure solvent)
Xm = mole fraction
24.9 mmHg - 23.8 mmHg = 23mmHg . Xm
Xm = (24.9 mmHg - 23.8 mmHg) / 23mmHg
Xm = 0.0462
One difference is
humans and animals only carry genes(traits Ex; like blue eyes and red hair phenotype) and plants carry chromosomes(energy from the sun)
