MissTica3 years ago
5 0

Answer: Option B. 76.83L

Explanation:

1 mole of a gas occupy 22.4L at stp. This implies that 1mole of Radon also occupy 22.4L at stp.

If 1 mole of Radon = 22.4L

Therefore, 3.43 moles of Radon = 3.43 x 22.4 = 76.83L

The reaction of Pb+4 and O-2 produces the compound of
vovikov84 [41]

Answer:

Pb₂O₄

                               

Explanation:

The given species are:

        Pb⁴⁺               O²⁻  

Now, to solve this problem, we use the combining powers which corresponds to the number of electrons usually lost or gained or shared by atoms during the course of a chemical combination.

                                          Pb⁴⁺               O²⁻  

Combining power               4                    2

Exchange of valencies        2                    4

Now the molecular formula is  Pb₂O₄

For a reaction:
torisob [31]

Looking at the equation .look at the moles noted below

  • Ca(OH)_2=1mol
  • NH_2Cl=2mol.
  • CaCL_2=1mol
  • NH_2=2mol
  • H_20=2mol.

#a

There is 2 moles of NH2Cl.

  • Hence limiting reagent is Ca(OH)_2

#2

Moles at reactant=3

Moles at product=5

Moles left:-

\\ \sf\longmapsto 5-3=2mol

#d

\\ \sf\longmapsto pV=nRT

\\ \sf\longmapsto 1.5V=2(8.3)(27)

\\ \sf\longmapsto 1.5V=448.2

\\ \sf\longmapsto V=\dfrac{448.2}{1.5}

\\ \sf\longmapsto V=298.8mL
