Air has about 21% oxygen
Exhaled air has about 16% oxygen
The gas produced from decomposition of H₂O₂ is pure oxygen
The gas produced from decomposition of NaHCO₃ is pure carbon dioxide
Thus, the order is:
1) Gas produced from decomposition of H₂O₂
2) Air
3) Exhaled air
4) Gas produced from decomposition of NaHCO₃

When the nuclide uranium-234 undergoes alpha decay: the name of the product nuclide is . the symbol for the product nuclide is?
Schach [20]
Answer is: <span>name of the product nuclide is thorium-230.
</span>

<span>Alpha particle is nucleus of a helium-4 atom, which is made of two protons and two neutrons.
²³</span>⁴U → ²³⁰Th + α (alpha particle).

Alpha decay is radioactive decay in which an atomic nucleus emits an alpha particle (helium nucleus) and transforms into an atom with an atomic number that is reduced by two and mass number that is reduced by four.

Molarity, is the concentration of a solution expressed in terms of moles solute per liter of solution. What is the molarity of a
pishuonlain [190]

molarity of the CuSO₄ solution = 0.68 moles/L

Explanation:

The formula for molar concentration is:

molar concentration (molarity) = number of moles / solution volume (L)

number of moles = mass / molecular weight

number of moles of CuSO₄ = 12.304 / 159.6

number of moles of CuSO₄ = 0.07709 moles

molar concentration of the CuSO₄ solution = 0.07709 / 0.1127

molar concentration of the CuSO₄ solution = 0.68 moles/L
