xxTIMURxx [149]

Answer:

e.)  If exposure to cowpox gives immunity to smallpox in milkmaids, then milkmaids have a natural immunity and their blood should be used to develop a smallpox vaccine.

Explanation:

  • Milkmaids who suffered from cowpox did not suffer from smallpox i.e. they were immune to the disease.
  • If milkmaids did not suffer from smallpox then there must be some element of immunity that they received once they had recovered from cowpox, this would likely be found in their blood as antibodies.

Which of the following samples will have the greatest volume at STP?a. 22 g Neb. 22 g Hec. 22 g O2d. 22 g Cl2 e. All have the sa
sammy [17]

Answer:

22g of He

Explanation:

Volume of gas at STP is given as :

Volume occupied(dm³) = number of moles x 22.4dm³mol⁻¹

In order to solve this given problem, we would first find the number of moles from the different masses of atoms and molecules given.

Number of moles = \frac{mass }{Molar mass}

Now, let us obtain the molar mass of the given atoms and elements:

For Ne; molar mass is the atomic mass = 20gmol⁻¹

      He = 4gmol⁻¹

      O₂ = (16 x2)gmol⁻¹  = 32gmol⁻¹

      Cl₂ = (35.5x2)gmol⁻¹ = 71gmol⁻¹

Number of moles of Ne = \frac{22}{20} = 1.1mol

Volume occupied by Ne at STP = 1.1 x 22.4 = 24.64dm³

       

Number of moles of He = \frac{22}{4} = 5.5mol

Volume occupied by He at STP = 5.5 x 22.4 = 123.2dm³

Number of moles of O₂ = \frac{22}{32}  = 0.688mol

Volume occupied by O₂ at STP = 0.688 x 22.4 = 15.4mol

Number of moles of Cl₂ = \frac{22}{71} = 0.3099mol

Volume occupied by Cl₂ at STP = 0.3099 x 22.4 = 6.94dm³
