Answer:

The radius of the atom Ta is 142pm

Explanation:

To solve this question we need to know that for a body-centered cubic lattice we have the equations:

X = 4/√3 R

<em>Where X is edge length and R is radius of the atom in the lattice.</em>

<em />

If adge length of unit cell is 328 pm:

328pm = 4/√3 R

328pm * √3 / 4 = R

142pm = R

The radius of the atom Ta is 142pm

Wine goes bad soon after opening because the ethanol ch3ch2oh in it reacts with oxygen gas o2 from the air to form water h2o and
lilavasa [31]
The balanced chemical equation of the reaction described above is,

                            C2H6O + O2 --> H2O  + C2H4O2

If we have 3.84 g of oxygen, we divide by its molar mass.
 
                               n = (3.54 g Oxygen gas) x (1 mole O2/ 32 g O2)
                                 n = 0.11 moles O2

Using ratio and proportion,

               number of moles of ethanol = (0.11 moles O2) x (1 mole C2H6)
                                                  = 0.11 moles C2H6

Then, we multiply the calculated value to its molar mass, 46 grams /mol.
                    mass of ethanol = (0.11 mol) x (46 grams / mol)
                                                = <em>5.06 grams</em>
